# Worksheet: Two-Step Input–Output Patterns

In this worksheet, we will practice finding the missing number and identifying patterns in input–output tables using two-step rules.

**Q2: **

The rule for this input-output table is **multiply by 6**.

The input numbers follow the pattern **add 1**.

What number is ?

The output numbers will also follow a pattern. Describe this pattern.

- AAdd 7
- BMultiply by 6
- CAdd 6

We can use the numbers in the table to calculate in two ways. What are they?

- A and
- B and
- C and

**Q3: **

The rule for this input-output table is **multiply by 4**.

Jacob has shown that the pattern for the input numbers is **subtract 3**.

Describe the pattern that the output numbers will follow.

- Amultiply by 4
- Bsubtract 12
- Csubtract 3

**Q5: **

Michael followed addition and subtraction rules to make a group of addition sentences.

What do you notice about the sums?

- AThey are all the same.
- BThe sums follow a pattern of adding 1.
- CThe sums are different and have no pattern.

Fill in the Blank: In an addition expression, if I add a number to one addend and the other addend, the sum stays the same.

- Aadd it to
- Bsubtract it from

**Q6: **

Complete the rule for the pattern: **Multiply by****, then add 2**.

- A2
- B4
- C5
- D6
- E3

**Q7: **

Complete the rule for the pattern: **Divide by****, then add 3**.

- A5
- B4
- C2
- D6
- E3

**Q9: **

The rule for this input-output table is **divide by 6**.

Benjamin has shown that the pattern for the input numbers is **add 12**.

Describe the pattern that the output numbers will follow.

- Amultiply by 6
- Bdivide by 6
- Cadd 2
