This Grade 4 worksheet builds skill with input/output tables for CCSS 4.OA.5. Students determine rules like multiply by 4 or add 7 from given input/output pairs, complete missing values, and match Grade 4 input plus rule combinations with their correct outputs in a focused matching task. Students study input-output tables and detect single-step rules like multiply by 4 or add 7 in this Grade 4 reasoning worksheet for mastery.

Patterns and Input/Output Tables
Part A: Fill in the Blank
Write the missing word or number on each line.
1. If input 2 gives output 8 and input 3 gives output 12, the Grade 4 rule is multiply by 4.
2. For inputs 1, 2, 3 the outputs are 8, 9, 10, so the Grade 4 rule is add 7.
3. If input 5 maps to output 25 and input 6 maps to output 30, the rule is multiply by 5.
4. For input 10 with output 2 and input 20 with output 4, the Grade 4 rule is divide by 5.
5. Inputs 4, 5, 6 give outputs 12, 15, 18, so the Grade 4 rule is multiply by 3.
6. If input 7 gives output 14 and input 9 gives output 18, the Grade 4 rule is multiply by 2.
7. When input 12 gives output 6 and input 18 gives output 9, the rule is divide by 2.
8. For inputs 0, 1, 2 with outputs 6, 7, 8, the Grade 4 rule is add 6.
9. Inputs 3, 4, 5 produce outputs 21, 28, 35, so the Grade 4 rule is multiply by 7.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
