At medium difficulty, first graders work with fact families through the teen numbers without scaffolded equation frames. Part A gives nine fill-in-the-blank equations where children write all four members of each family, such as 5 + 9, 9 + 5, 14 - 5, and 14 - 9. Part B introduces a matching activity that pairs addition equations with their subtraction partners, training children to spot related facts quickly across different number combinations.

Fact Families: Addition & Subtraction
Part A: Complete the Fact Family
Write the missing number to complete each equation.
1. 5 + 9 = 14
2. 9 + 5 = 14
3. 14 - 5 = 9
4. 14 - 9 = 5
5. 7 + 8 = 15
6. 8 + 7 = 15
7. 15 - 7 = 8
8. 15 - 8 = 7
9. If 6 + 8 = 14, then 14 - 6 = 8.
Part B: Match the Fact Family Partners
Draw a line from each addition fact to its subtraction partner.
1. Match each addition fact to its subtraction partner.
4 + 9 = 13
→ 13 - 9 = 4
12 - 5 = 7
6 + 8 = 14
→ 14 - 8 = 6
13 - 9 = 4
7 + 5 = 12
→ 12 - 5 = 7
12 - 9 = 3
3 + 9 = 12
→ 12 - 9 = 3
14 - 8 = 6
Fact Families: Addition & Subtraction
★ Part A: Complete the Fact Family
Write the missing number to complete each equation.
1) 5 + 9 = 14
2) 9 + 5 = 14
3) 14 - 5 = 9
4) 14 - 9 = 5
5) 7 + 8 = 15
6) 8 + 7 = 15
7) 15 - 7 = 8
8) 15 - 8 = 7
9) If 6 + 8 = 14, then 14 - 6 = 8.
★ Part B: Match the Fact Family Partners
Draw a line from each addition fact to its subtraction partner.
1) Match each addition fact to its subtraction partner.
4 + 9 = 13
→ 13 - 9 = 4
12 - 5 = 7
6 + 8 = 14
→ 14 - 8 = 6
13 - 9 = 4
7 + 5 = 12
→ 12 - 5 = 7
12 - 9 = 3
3 + 9 = 12
→ 12 - 9 = 3
14 - 8 = 6
