Present Families: Christmas Addition and Subtraction Fact Families to 20

Student Task

• Draw a present with 4, 6 and 10 on it. Ask: "Which number sentences can you make with only these numbers?"
• Do activities 1 and 2 together, writing all four facts.
• Children complete activities 3 to 6. Answers are in the answer key.

Classroom Use

• Present families: children write three numbers on a paper present and the four facts inside.
• Fact family houses: four children each hold one fact and stand in the same house.
• Missing number bells: say 8 + ___ = 13; children ring a pretend bell and say the answer.

Differentiation

Support: use counters and start with families to 10. Challenge: children find all the fact families with the whole 12 and explain why 6, 6, 12 has only two facts.

Answer Key & Assessment

Activities 1 to 5 check fact families, missing numbers and story problems (answer key included). Activity 6 shows whether children can make their own fact family.

Learning Objectives

• Write the four facts in a fact family with numbers to 20.
• Use a known addition fact to find a missing number or solve a subtraction.
• Solve simple addition and subtraction story problems.

Teacher Tips

In a fact family, the biggest number (the whole) comes first in a subtraction and last in an addition. Show this with counters: 10 presents split into 6 and 4 can be put together (add) or taken apart (subtract).
