Instructions: Work through the activities in order. You may use your fingers or draw little marks to help you count. Read each number sentence carefully, and write one answer in every box.

Read and Complete Number Sentences

The plus sign means add, and the minus sign means take away. The equals sign means that both sides have the same value. Work out each number sentence and write the missing number in the box.

1. 4 + 3 =

2. 9 - 5 =

3. 6 + 0 =

4. 12 - 2 =

Number Bonds and Take-Away Facts

A number bond shows two parts that make a whole. Find the missing part in each sentence. For the take-away facts, think about how addition can help you check your answer.

1. 6 + = 10

2. 8 + = 10

3. 7 + = 12

4. 15 - 6 =

5. 18 - 10 =

Add and Subtract to 20

Solve each calculation. You can count on to add or count back to subtract. Remember that adding zero does not change the number.

1. 8 + 5 =

2. 14 - 3 =

3. 10 + 7 =

4. 19 - 6 =

5. 3 + 0 =

Find the Missing Number

The missing number is shown by a question mark. Work out what number makes each sentence true. Read carefully: the missing number may come before or after the equals sign.

1. 7 = - 9

2. + 4 = 11

3. 16 - = 10

4. 5 + = 13

Picture Problems

Count the pictures, then use the number sentence to solve each problem. Write the answer in the box. The pictures are there to help you imagine the objects in the story.
