### MATH MAT AND TEN FRAME

Math mats are a “hands on” way to give children concrete experiences with addition and subtraction. Trim a file folder to make a 12” square. Draw a line down the middle of the square as shown. Draw a line down the middle of the top section. Explain that the line in the middle is like the equal sign in an equation. What is on the top has to equal (be the same as) what is on the bottom.

Note! Poker chips, small toys, natural items, small erasers, and other objects can be used with the math mat. You can also make smaller math mats from an 8" square.

Demonstrate how to use counters to make a set in the top left section and a set in the top right section. Count. Pull down the objects into the bottom section and count how many altogether.

Subtraction
Use counters to demonstrate subtraction.

”If I have 3 and I want 8, how many more do I need? Let’s put 8 in the bottom. Now, move 3 to the top. How many more do you think I’ll need?” Continue to let children move the counters to solve similar problems.

TEN FRAME

A ten frame will give children another "hands-on" way to explore math concepts.
Note!  Five, ten, and twenty frames are available to download on the internet.

Building Sets
Call out a number and demonstrate how to place the counters in the frame starting on the left. Remind them to always start with the first frame on the left.
*Turn the frame vertically to make sets.
*Can you place the counters in a different way?
*Have children count forwards and backwards on their frames.
