# Lesson 3 Specific Side Lengths

• Let’s find and draw shapes with specific side lengths.

## Warm-up Which One Doesn’t Belong: Different Shapes

Which one doesn’t belong?

## Problem 1

Diego drew a shape that has fewer than 5 sides. Two sides are 3 centimeters long. Circle shapes that could be Diego’s shape.

## Problem 2

Tyler drew a shape that has 4 sides. Each side is 2 inches long.

1. Circle shapes that could be Tyler’s shape.

2. Draw another shape that could be Tyler’s shape.

3. Priya drew a shape that has more sides than Tyler’s shape. Only one side of her shape is 2 inches long. Draw two shapes that could be Priya’s shape.

## Problem 1

1. Choose your own attributes. Circle an attribute from each row.

## Problem 4

Cover your attribute table and trade papers with your partner. Guess which attributes they used to draw their shape.

## Problem 5

If you have time… Are there any attributes that are impossible to put together to make a shape? Show or explain.

## Problem 1

1. Draw a quadrilateral that has 3 sides that are 2 inches long.

2. Draw a different quadrilateral that has 3 sides that are 2 inches long.
