**Math Help**

Here you will find what your child is working on in math. It will help you understand what your child is learning and enable you to help them with these skills! Here is a link to several FREE Math Apps that you can download to practice skills at home. www.mathlearningcenter.org/resources/apps

**Math Rack**

You may hear your child talk about using a tool in class called a "Math Rack". While the ones we use in class are hand-made and smaller, they have two rows of red and white beads, and the teachers have large demonstration ones, just like the ones in this video. If it reminds you of a small abacus--you're not alone. This video helps explain some of the ways it can be used to help children develop strategies for addition and subtraction facts.

**Bridge to 10 Strategy**

Bridging to 10 basically means that students can use what they know about making tens to help them learn facts when the numbers you are adding or subtracting together are close to ten.

For example: to solve 9+5, someone can think that 9 is one away from 10.

If you take 1 from the 5, and give it to the 9, then instead of 9+5, you can solve for 10+4. Both equal 14.

9 + 5 = 14

__+1__

__-1__

10 + 4 = 14

We want students to get comfortable using this strategy with small numbers, so that as we transition into larger numbers, the same strategy can help them. For example:

49 + 35

__+ 1__

__- 1__

50 + 34

Then we would probably split the 34 into 30+4, and add 50+30=80. Then 80+4=84.

49+35=84, just as 50+34=84.

Watch the video below for more of an explanation.

**Doubles Strategy**

This strategy includes facts that double numbers. Doubles facts are important not only for addition, but they are also used as the basis for learning multiplication facts [x2 "Double", x4 "Double Double", and x8 "Double Double Double"] in the future.

We also use our doubles facts to relate them to facts with addends just one or two more than a double fact:

**Doubles +1**

6+6=12

so we know that: 6+

**6+1**=13 which is equal to 6+

**7**=13

and its turnaround fact 7+6=13

**Doubles +2**

5+5=10

so we know that: 5+

**5+2**=11 which is equal to 5+

**7**=12

and its turnaround fact 7+5=12

**Count On Strategy**

The Count On strategy is basically, "Don't start again...count ON."

For example, if you have 5 of something, and want to add 2 more, there is

**no need to start from 1 and count all of the objects over again as a larger group.**

Just start with 5, and count up 2 more [6, 7] up to 7.

5 + 2 = 7

**Place Value: Number of the Day**

This week we are discussing place value. We are reading, writing, creating, and understanding the value of each place of number up to 1,200. Here are different ways to look at this number:
