This easy worksheet revisits the same building blocks with fresh numbers, giving early first graders a second pass without raising the difficulty. Part A traces parts, minus, fact, sum, add, and family to lock in vocabulary. Part B steps through the 6-8-14 family in full: 6 + 8 = 14, 8 + 6 = 14, 14 - 6 = 8, and 14 - 8 = 6, showing how one related set of numbers makes four equations.
Part C tests judgment with statements like '2 + 9 = 11 paired with 11 - 2 = 9' (true) and a deliberate trap pairing 7 + 5 = 12 with 12 - 6 = 6 (false). Catching that mismatch is exactly the reasoning skill that prevents fact family errors later.
Style:
Fact Families (Addition & Subtraction to 20)
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. parts
2. minus
3. fact
4. sum
5. add
6. family
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 6 + 8 = 14
2. 8 + 6 = 14
3. 14 - 6 = 8
4. 14 - 8 = 6
Part C: True or False?
Read each statement. Circle True or False.
1. 2 + 9 = 11 is in the same fact family as 11 - 2 = 9.
True False
2. 7 + 5 = 12 is in the same fact family as 12 - 6 = 6.
True False
3. 8 + 4 = 12 is in the same fact family as 12 - 4 = 8.
