Illustrating Fraction and Whole Number Products with Tape Models
Need extra help for EL students? Try the Comparing Tape Diagrams pre-lesson.
Students will be able to use tape diagrams to create equivalent expressions involving whole numbers, fractions, and multiplication.
- 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.
- 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.
- 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.
