Making Math Count in the New Year!



Making Math Count in the New Year!

“Math is a language of logic.  It is a disciplined, organized way of thinking.  There is a right answer; there are rules that must be followed.  More than any other subject, math is rigor distilled.  Mastering the language of logic help to embed higher-order habits in kids’ minds: the ability to reason, for example, to detect patterns and to make informed guesses.  Those kinds of skills had rising value in a world in which information was cheap and messy.”  Esther Cepeda, Daliy News, 2/23/14.

This excerpt is from an article “Why math? Why not?” from the Daily News and it makes a very important point: math teaches your child much more than just how to add and subtract, math teaches your child how to be a logical adult with strong reasoning skills.  Math is an intricate part of our everyday life.  Think about your daily routine and how many times you have had to problem solve a difficult situation or make reasonable deductions.

Here is a problem for all ages from Bed Time Math - http://bedtimemath.org/   if you haven't had a chance to check this website out I would highly recommend it.  There are many quick "thinker" problems that you can add to your bedtime routine.

Here's your nightly math! Just 5 quick minutes of number fun for kids and parents at home. Read a cool fun fact, followed by math riddles at different levels so everyone can jump in. Your kids will love you for it.

KING OF THE GARBAGE CAN


December 12, 2016
You probably know that it isn’t a great idea to eat out of the garbage. But for animals like rats, goats, and cockroaches, it’s a yummy treat. The smartest of these guys may be the raccoon. Raccoons, known for their funny black masks and poofy ringed tails, love breaking into people’s garbage cans and flinging leftovers everywhere as they snack. And they’re really clever about it, as we’ve seen here ourselves: the neighborhood raccoon always finds a way to undo the latch, tip the can over, and pop off the top.  In fact, studies have found that raccoons are smart enough to open 11 out of 13 different complex locks, and can also remember tricks 3 years after learning them. We hope we can do that, too!
Wee ones: A raccoon has 5 claws on its front paw. Is that more than, less than, or the same as the fingers on your hand? Count to check!
Little kids: If a raccoon starts breaking into your garbage at 8 pm and succeeds 2 hours later, when does he get in there? Bonus: If you put 13 locks on your garbage can and the raccoon can open 11 of them, how many locks are still stopping him?
Big kids: If a raccoon opens the 12th lock in a giant row, then the 16th, then the 20th, what lock does he open next to keep the pattern?  Bonus: If there are 42 houses on your street and the raccoons break into half of them, how many people’s garbage cans do they invade?
Wishing you a Happy Math Year!
Victoria Saldana
Math Specialist/Instructional Coach
  
Answers:
Wee ones: The same number as your 5 fingers.
Little kids: At 10 pm.  Bonus: 2 locks.
Big kids: The 24th lock.  Bonus: 21 houses.

Turkey Math



It is hard to believe that December is just around the corner but first let's talk Turkey, turkey math of course.  Think about all the math you have to do to put a meal together.  Involve your kids in these types of decisions.

  1. How big of a turkey to get to serve all the guests, how many pounds of potatoes you need to make 8 servings of mash?   
  2. For the younger ones, ask them to figure out how many place setting, spoons, forks and so forth are needed for all the guests.  
  3. You can also estimate how many oz or gallons of beverages will be consumed and then see if you were close after the holiday. 

Here are some fun facts to impress your family and friends -


  • According to the National Turkey Federation, 88 percent of Americans have turkey on Thanksgiving. So if our math is correct, that leaves 12 percent of people who don't eat turkey on the holiday.
  • A lot of cranberries are needed to accompany all that turkey on Thanksgiving. In all, 768 million lbs. (350 million kilograms) of cranberries were produced in the United States last year. Two states — Wisconsin and Massachusetts — were responsible for most of the production, producing 450 million and 210 million lbs. (200 million and 95 million kg) of cranberries, respectively.
  • Turkey was the first meal enjoyed by Neil Armstrong and Buzz Aldrin when they were on the moon. Now you can be the talk of your dinner table this holiday — a perfect turkey tidbit to impress holiday dinner guests.
                                                             -from http://www.livescience.com/41506-surprising-thanksgiving-facts.html

Happy Thanksgiving!

Jefferson Problem Solving Board is in full swing!


Jefferson Problem Solving Board

I am very excited to see so many students at my board every morning this week.  I already had to empty my basket twice because it was filled with returned work.  New problems will be posted Monday, November 14 (about every 2 weeks).

A notice was sent home last week via your child's backpack, in case you missed it below is a description of how this program works.  If you have any questions please call or email me: saldanav@

What is the Jefferson Problem Solving Board? - This program gives students extra practice with critical thinking skills in grades 1-5.  Who should participate? Everyone! Due to the fact that this program is leveled by grade level cluster and the problems themselves are leveled, students of all math abilities can participate.  This set up allows for remediation and enrichment.

How does this work?
1. Student selects a problem set from their grade cluster.
2.  The problems themselves are leveled.  Each problem has a star next to it.
     1 star is easy - 4 stars is difficult.
3.  The student completes these problems on their own time, no deadline.          
     He/she doesn't have to complete all the problems, if the 4 star problems are  
      too challenging for example, then they can be skipped.
4. Once the student completes the problems, then he/she can bring the  
     problems back to the math specialist to be corrected.

For every twenty five stars that the students earn (25, 50, 75 and 100) they get their name on the Math Super Star board, their name is announce in the morning announcement, and they get a special prize from the math specialist.

What kind of problems will the kids get to work on? The problems are a mixture of word problems, math puzzles, basic number operation reviews and most importantly they are fun to do.

Welcome Back!


Great to be back, I am looking forward to my second year at Jefferson Elementary. Over the summer the teachers in the district added some wonderful math lessons and projects to our curriculum that promote critical thinking and strengthen problem solving skills.  We are looking forward to a lot of great math learning. 

The Problem Solving Board is slated to start this year in late October.  I will talk more about this during our curriculum night on September 15th.

I am including a link to some "must have math apps" for you and your child to try out:

Wishing everyone a great start to the school year

Summer Math and Fun Ways to Avoid Summer Brain Drain!




Fun Ways to Avoid Summer Brain Drain!

During the fun summer months children tend to forget some of the academic skills learned during the school year.  Helping your child avoid the summer “brain drain” can be easy and lots of fun. Math games are a great way not only to occupy your child but also to keep their skills sharp in the summer. Read on for ideas!

Resources for you Going Home with Report Cards: Every student will get a calendar where they color in a sun for every problem that they complete over the summer.  We are asking that students complete at least 15 problems each month (July and August).  The problems cover most of the skills that they learned this year.  We will be collecting the calendars (and reading logs) in September.  
Fluency: You will also receive a fluency letter from me (blue paper) with tips and fun resources on how to support this skill over the summer. Your child's latest results will also be attached to give you a starting point.  Teachers have been working all year to build up fluency and we would like to ask you to help continue this practice to ensure that the kids retain what they learned and practice facts that they are still working through. 

District link to the summer math and reading logs if you need to replace a copy:

Recommended Daily Math Activity Time
Students entering Pre K, K and grade 1 = minimum 5 minutes
Students entering grade 2 = minimum 10 minutes

Providing Enriching Math Opportunities for Your Child - Resources provided


Math enrichment gives your child opportunities to think like a true mathematician and extend what they learn in a standard classroom to the real world.  This develops the critical thinking section of their brains which we all know is like a muscle so the more it is used the more proficient it becomes.

Giving your child a chance to struggle through a problem that is at their level this which means  instead giving your 2nd grader multiplication and division problems, rather dive deep into what they have learned already.  Question their thinking, have your child justify their answer to you.  If they are working on a number puzzle, ask them if the rule they identify applies to all situations.

Good questions to ask:
"is this always true?"
"can you find an example to make this not true?"
"how can you prove that your answer is correct?"
"is there another way you could solve this?"

Below are some resources that are great to use for these type of activities.  Include some of the questions mentioned above when your child works the problems out.  And remember to give them that very important opportunity to struggle through a problem.  Real mathematicians get problems wrong repeatedly but they keep on trying until they persevere though them.

Fun fact: the longest math problems took 365 years to solve.  Google Fermat's Last Theorem.

Story Time? How about Bed Time Math

One of the biggest topics in mathematical education is the integration of math concepts into “real world” scenarios.  When children see how we as adults use mathematics in our daily life it makes learning the subject relevant for them.
  
Recently, I came across a very interesting article in Time magazine entitled “Beyond Counting Sheep.  Why math is the hot new bedtime reading”, by Bonnie Rochman.  This article is about an astrophysicist turned stay at home mom whose mission is to “change the way parents put their kids to bed”.  The mom, Laura Bilodeau Overdeck, is the founder of a great web-site called Bedtime Math  (Bedtimemath.org).  This web-site offers interesting “real world” problems that are fun for every age group and center on current events, holidays, and home life.  Her vision is to have parents problem solve with their children as part of their nightly routine; as you would read your child a story, you would also solve a problem together.  Solutions to each problem can also be found on this web-site.
I hope you have an opportunity to try this web-site and approach out. 

In the meantime here are some sample problems from Bedtimemath.org:

Skydiving has been a favorite topic here, because there are few things in life as dramatic as hurling yourself out of a plane from thousands of feet above the ground. Well, this group of 100 skydivers took it to a new level: they all jumped out of planes at the same time, then used their wingsuits to steer themselves into a nice neat square formation of people in the sky. It set the record for the number of people in one skydive formation – well, okay, that’s because it’s the first formation anyone has turned in for the record. But given that it took 100 people from 21 countries jumping out of 5 planes, they obviously earned the honor.

Wee ones: If you were one of the divers and you were on the 1st of the 5 airplanes to take off, how many planes took off after you?
Little kids: The skydivers jumped from 13,000 feet. If they didn’t pull their parachutes until they were 6,000 feet above the ground, for how many thousands of feet did they fall first? Bonus: If the 100 skydivers were divided evenly among the 5 planes, how many people jumped out of each one?

Big kids: The 100 divers spread out in an almost perfect square in the sky. If it had been a perfect square, how many people wide would that square have to be? Bonus: To skydive wearing a wingsuit, you need to do at least 200 dives before that. At least how many dives must the group of 100 have done in total before this? (Hint: to multiply a number by 100, tack 2 zeroes on to the end of it.)

The Collaborative for Student Success has recently published a brief article called "Falling Back in Love with Math."  They paraphrase an interview the Washington Post conducted of parents and their view of the Common Core.  During the interview the parents stated that they saw a significant impact on their children understanding of math concept that the revised curriculum under the Common Core has had on their children.
The article is below:

Falling back in love with math

valentines-blogParents around the country have expressed trepidation about new math instruction they don’t recognize and rightful concern that they are unable to help their children with their homework. But, some parents have come to the realization that they want their children to be better and more confident at math than they were as students. And the more they learn, the more parents are starting to appreciate the math concepts promoted in the Common Core State Standards.
Here’s what some parents recently told Washington Post’s Jay Mathews when asked their thoughts on Common Core math:
“Like many parents in the early years, we were confused by the math in particular and not very supportive…[But now my twin daughters] understand math concepts so completely after learning ‘that crazy way’ in elementary school that I am a huge believer. They reason and understand. They do not memorize and move on.” – Maryland parent, Marianne Sullivan
“My first reaction to a Common Core worksheet was repulsion. It’s ugly math. It doesn’t look pretty or easy… [But] I set that aside and learned how to do what he was doing. And something magical happened: I started doing math better in my head.” – Washington State parent and tutor, Hadley Danielson
Certainly, not all material should be new to parents. Common Core State Standards still require students to know basic procedures and traditional problem-solving methods.Zimba explains in a piece this month, but the standards also encourage having kids learn multiple approaches to solving math problems so that they can choose the approach that works best for them, and so that they develop a full understanding of the concepts before they move on to more challenging levels.
This Facebook post from an Idaho teacher demonstrates exactly how that complete understanding translates to making more complex math concepts easier for students to grasp:
“We whipped through this in a day because they were able to conceptually understand the idea of splitting the area of a rectangle into easier to compute pieces, and then finding the sum of the pieces. Is this method the most efficient for multiplying simple two digit numbers? Probably not. But is there a PURPOSE for exposing students to this kind of thinking early on? Totally! … I just love seeing Common Core working!”

Making Math "Count" in the New Year!

“Math is a language of logic.  It is a disciplined, organized way of thinking.  There is a right answer; there are rules that must be followed.  More than any other subject, math is rigor distilled.  Mastering the language of logic help to embed higher-order habits in kids’ minds: the ability to reason, for example, to detect patterns and to make informed guesses.  Those kinds of skills had rising value in a world in which information was cheap and messy.”  Esther Cepeda, Daliy News, 2/23/14.
This excerpt is from an article “Why math? Why not?” from the Daily News and it makes a very important point: math teaches your child much more than just how to add and subtract, math teaches your child how to be a logical adult with strong reasoning skills.  Math is an intricate part of our everyday life.  Think about your daily routine and how many times you have had to problem solve a difficult situation or make reasonable deductions.

As parents/guardians we can make a big impact in our children’s mathematical development by incorporating small habits into our routines. Below are three “must do’s” for our elementary aged children:

1. Count with your child – this simple activity develops strong number sense and gives your child a significant advantage over peers who come to school not being able to count.
Ø  Pre K and K aged students – count to 100 by 1’s forward and backwards.  Count to 100 by tens   (10, 20, 30 …). 

Ø  Grades 1 and 2 – count to 1,000 and above.  Count by 5’s (0, 5, 10, 15…); 10’s; 100’s (100, 200, 300 …).  Count within 100’s by 10’s forward and backwards (210, 200, 190, 180…)

Ø  Grades 3 and 4 – count with high numbers (1million, 2 million, 3 million… 100,000, 200,000, 300,000).  Count fractions (1 ½; 2; 2 ½; 3; 3 ½; 4…. OR ¼; 2/3; ¾; 1; 1 ¼; 1 2/4; 1 ¾; 2…)
2.  Play “I am thinking of a number” game - this type of activity develops your child’s understanding how our number system is ordered.
For example:
Ø  Pre K and K aged students – “I am thinking of a number that comes before 5”; “I am thinking of a number that comes after 10”; “I am thinking of a number that comes in between 14 and 16”. 

Ø  Grades 1 and 2 – “I am thinking of a number that comes before 105 but after 102”; “I am thinking of a number that is ten less than 50”; “I am thinking of a number that is greater than 150 but less than 154”.

                  Ø  Grades 3 and 4 – Break the numbers down by place value (see diagram below) “I am                            thinking of a number that has 2 thousands, 3 hundreds, 2 tens and 4 ones – what is my                          number?” (2,324).  “I am thinking of a number that has 3 ones and 4 tenths” (decimal                          place value – 3.4)



3. Practicing math facts - Parents play a vital role in supporting this at home. Practicing 10 minutes a day will really improve math fact fluency. Try practicing math facts in the car, when shopping, while practicing sports (basketball/soccer - around the world with math facts) or while cooking. There are also many fun math websites, math apps, and math games that can help your child.


Wishing you a Happy Math Year!
