## Warm-up Notice and Wonder: Four Number Lines

What do you notice? What do you wonder?

## Activity 1 Hidden Whole Numbers

## Problem 1

On each number line, circle the fractions that are equivalent to whole numbers. Explain how you know.

## Problem 2

We can write

Write 5 other equations that show fractions that are equivalent to whole numbers. Use the number lines if they are helpful.

## Problem 3

Decide if each fraction is equivalent to a whole number. Use number lines if they are helpful.

## Activity 2 Write Them as Fractions

Work with your group to complete the table. In each column, write fractions that are equivalent to the whole number in the top row.

Step 1: Write two fractions that are equivalent to each whole number (six fractions in all). Pass your paper to your right.

Step 2: When you receive your neighbor’s paper, write a new fraction that is equivalent to a whole number.

Repeat Step 2 until the table is complete.
