Stop, look, and think,
Before you add or subtract.
Pay attention to the signs
When you do your math!
Plus sign, plus sign,
What do you say?
Put them together.
Join sets, I say!
Minus sign, minus sign,
What do you say?
Subtract a set.
Take it away!
Equal sign, equal sign,
What is your game?
The amount on either side
Is always the same.
Look at the signs before you begin,
And your answer will always win!
Hint! Here is a tool that can help children solve word problems. Fold a sheet of paper into fourths. Open and fold in half. Cut half way up one creased line as shown. Make a “+” on the right and a “-“ on the left. Lift flaps and write key words for adding and subtracting. For example:
Subtraction: less, minus, left, take away, fewer, difference
MATH FACTS Musical Chairs
Place chairs in a circle and PUT A MATH FLASHCARD ON EACH CHAIR.. Play some music for the children to march around. When the music stops they have to identify the ANSWER TO THE EQUATION where they are standing.
*Make the game more difficult by putting several coins for the children to count.
MATH MATS
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.
Addition
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.
