This Grade 4 patterns and input/output tables worksheet focuses on shrinking number sequences using subtraction rules. Students examine sequences like 50, 45, 40, 35 and 100, 90, 80, 70 to find missing terms and name the function rule. Through sentence corrections, fill-in-the-blank prompts, and short answers, learners practice subtracting constant amounts and explaining the relationship between consecutive terms in a clear, accessible Grade 4 format that supports fluency and reasoning steadily.

Patterns and Input/Output Tables
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The Grade 4 sequence 50, 45, 40, 35 increases by 5 each time.
Rewrite: The Grade 4 sequence 50, 45, 40, 35 decreases by 5 each time.
2. Fix the sentence:
In the Grade 4 sequence 100, 90, 80, 70, the next term is 65.
Rewrite: In the Grade 4 sequence 100, 90, 80, 70, the next term is 60.
3. Fix the sentence:
The Grade 4 rule for 24, 21, 18, 15 is subtract 2 each time.
Rewrite: The Grade 4 rule for 24, 21, 18, 15 is subtract 3 each time.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The Grade 4 sequence 50, 45, 40, 35 has the rule subtract 5 each time.
2. In the Grade 4 sequence 80, 70, 60, 50, the next term is fifty.
3. If a Grade 4 sequence starts at 36 and the rule is subtract 4, the second term is 32.
4. The Grade 4 sequence 90, 81, 72, 63 has a function rule of subtract 9 each step.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Write the next two terms in the Grade 4 sequence 64, 56, 48, 40 and name the rule.
The rule subtracts 8, so the next two terms in this Grade 4 sequence are 32 and 24.
2. Explain how to find the missing term in the Grade 4 sequence 75, 70, ___, 60, 55.
The rule subtracts 5, so the missing term in this Grade 4 sequence is 65.
