The purpose of this lesson is for students to connect situations involving equal groups to tape diagrams.
This lesson introduces tape diagrams as a way to represent equal groups and multiplication, building on students' work with scaled picture graphs and discrete drawings of equal groups. Students deepen their understanding of multiplication as they connect tape diagrams to situations that involve equal groups. They are then introduced to multiplication expressions as a way to represent the quantities and situations encountered in the lesson. This happens at the end to allow students to work with other representations of multiplication before they learn about abstract symbols that represent multiplication.
Activity 2: Card Sort: Equal Groups
- Interpret a situation involving equal groups and represent it with a diagram.
- Make sense of tape diagrams that represent multiplication.
- Let’s represent equal groups.
