### Math

MATH NEWS

Your child is responsible for practicing math facts regularly during the week as part of their homework.  You may also practice using other ways!

1. Play cards (i.e. Use a deck to make addition and subtraction games; there are also -addition/subtraction WAR decks available).

2. Many board games require the children to count money or other items. Nice family time as well. :-)

3. Math web sites.

4. Fact cards.

5. Target/Dollar Store white boards or dry-erase math fact placemats for practice.

6. Counting items from the kitchen...adding/subtracting groups of items in the household.

7. Counting change.

Addition and Subtraction Tools and Strategies We Use:

Manipulatives:

These are hands-on materals we use in class for math.

Hundred Chart:

A chart of 1-100 that many students like to use for adding and subtracting. They are better able to visualize the pattern of adding or subtracting tens. You can find a 100 chart to print out on-line at (apples4theteacher.com)

Base Ten Blocks:

These are used to build numbers and solve problems. Students also draw base ten blocks to show their thinking when solving a problem. Base ten blocks help students decompose (or take apart) numbers to show 100's, 10's, and 1's.

Number Lines:

Number lines are created to solve problems. Students may use increments of ones, or use more efficient increments of tens. For example, in the problem 68 + 15, students would begin the number line at 68 and hop ten 68 + 10 = 78 then hop 5 +5 for final sum of 83

Drawing Pictures

This is a useful strategy for solving story problems. This is the best tool for visualization and understanding of a problem. After a drawing, the student will then be asked to write a number sentence that tells about it.

Showing Work

It is important to show your work and thinking. Students are required to show their work in pictures, numbers, words, or a combination of these things so I know how they arrived at their answer(s).

Strategies:

1. Use a 100 chart

2. Use number lines

3. Use doubles (Example: 7+8, say 7+7 = 14, so 7+8 = 15)

4. Use addition to solve subtraction (Example: 13-9, 9+4 = 13, so 13-9 = 4)

5. Counting on

6. Counting back
