Learning Objectives

Students will be able to use tape diagrams to create equivalent expressions involving whole numbers, fractions, and multiplication.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

Introduction

(5 minutes)
  • In front of your class, draw a rectangle divided horizontally in half. The upper half should be divided into two equal parts and the lower half into six equal parts.
  • Have students think, pair, and share a possible math expression the illustration might represent. Share out student ideas to the whole class.
  • Tell your students the illustration can serve as a powerful math tool called a tape diagram, a diagram that expresses equality between a lower level amount, and an upper level amount.

Beginning

  • Allow students to use their home language (L1) or new language (L2) in their discussions.
  • Provide visuals and definitions in their L1 and L2 of all the new vocabulary terms.

Intermediate

  • Write the academic language students can use throughout the lesson on the board as you introduce the language.
  • Have them share ways they've used tape diagrams in the past.
