Reisha plays in three basketball games. She scores 12 points in Game 1, 8 points in Game 2, and 16 points in Game 3. Each basket that she made was worth 2 points. She uses tape diagrams with a unit size of 2 to represent the points she scored in each game.

How many total units of 2 will it take to represent the points she scored in all three games?

Lesson 2 Concept Development

Problem 1: Rotate tape diagrams to make vertical tape diagrams with units of 2.

Problem 2: Draw vertical tape diagrams with units of 4.

1. Adi surveys third-graders to find out what their favorite fruits are. The results are in the table below.
