Compare two different ways to use tape diagrams! This lesson discusses fractions and multiplication within tape diagrams. Use this lesson as support for the lesson Illustrating Fractions and Whole Number Products with Tape Models.
Students will be able to use tape diagrams to create equivalent expressions involving whole numbers, fractions, and multiplication.
Students will be able to compare tape diagrams that have whole numbers and fractions using group discussions and visuals.
Draw a tape diagram for 3/4 with 3 rectangles filled and one clear and ask students tell their partner the number the tape diagram represents. Choose a student to share aloud the answer.
Write the student-friendly language objective on the board and have students choral read it with you: "I can compare tape diagrams that have whole numbers and fractions using group discussions and visuals." Challenge students to raise their hand when they hear a vocabulary term they would like to define (e.g., "tape diagrams," "whole numbers," "visuals," "fractions").
Distribute the vocabulary cards and ask students to help you define the terms from the language objective. Draw visuals on their cards to represent each of the terms.
Tell students that today they will compare tape diagrams that show different information visually.
