Building on easy-1, this sheet stretches fact family practice into numbers up to 15 while staying gentle for early first graders. Part A asks children to complete equations for three new families, and Part B presents missing-number fills like 5 + 8 = 13, then 13 - 8 = ___. Part C uses true-or-false questions that test whether three given numbers actually form a family, reinforcing the rule that two parts must equal the whole.

Part B: Fill in the Missing Number
Read each sentence. Write the missing number on the line.
1. If 5 + 8 = 13, then 13 - 8 = 5.
2. The numbers 6, 9, and 15 form a fact family.
3. If 9 + 6 = 15, then 15 - 9 = 6.
4. 8 + 5 = 13, so 13 - 5 = 8.
5. The fact family for 5, 8, and 13 has 4 equations.
Part C: True or False
Read each statement. Write True or False.
1. 5 + 8 = 13 and 13 - 5 = 8 are in the same fact family.
True False
2. The numbers 6, 8, and 15 form a fact family.
True False
3. If you know 9 + 6 = 15, you also know 15 - 9 = 6.
True False

★ Part B: Fill in the Missing Number
Read each sentence. Write the missing number on the line.
1) If 5 + 8 = 13, then 13 - 8 = 5.
2) The numbers 6, 9, and 15 form a fact family.
3) If 9 + 6 = 15, then 15 - 9 = 6.
4) 8 + 5 = 13, so 13 - 5 = 8.
5) The fact family for 5, 8, and 13 has 4 equations.
★ Part C: True or False
Read each statement. Write True or False.
1) 5 + 8 = 13 and 13 - 5 = 8 are in the same fact family.
True
False
2) The numbers 6, 8, and 15 form a fact family.
True
False
3) If you know 9 + 6 = 15, you also know 15 - 9 = 6.
