Add: How many
colored balls? __ + __ = 10
Subtract:
Cover
the colored balls. 10 − __ = __ |
Add:
__ + __ = 7 Subtract: Cover the colored balls.
7 − __ = __ |
1. Make an addition sentence and a subtraction sentence from the same picture.
|
__ + __ = __ 7 − __ = __ |
__ + __ = __ 6 − __ = __ |
|
__ + __ = __ __ − __ = __ |
__ + __ = __ __ − __ = __ |
2. In each problem, draw some white and some colored balls to fit the
addition sentence. Then cover the COLORED balls and make a
subtraction sentence.
|
Add: 7 + 1 = __ Subtract: __ − __ = __ |
Add: 6 + 3 = __ Subtract: __ − __ = __ |
|
Add: 9 + 1 = __ Subtract: __ − __ = __ |
Add: 7 + 2 = __ Subtract: __ − __ = __ |
3. Cover colored balls/squares/stars, and write a subtraction sentence to fit
the picture.
|
__ − __ = __ |
__ − __ = __ |
|
__ − __ = __ |
__ − __ = __ |
4. Lastly, draw the balls or squares yourself to fit the subtraction sentence. And, write an addition sentence too.
|
9 − 4 = __ __ + __ = __ |
10 − 5 = __ __ + __ = __ |
14 − 3 = __ __ + __ = __ |
