Unit 1, Lesson 10
Situaciones, dibujos, y diagramas, ¡oh, vaya!
Grado 3
Preparation
Lesson Narrative
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 of the lesson, so students work with other representations of multiplication before they learn about abstract symbols that represent multiplication.
- Engagement
- MLR8
- Comprehend the term “multiplication” (in spoken language) refers to a way to represent the total number of objects when you have a certain number of equal groups.
- Interpret a situation with equal groups and represent it with a drawing or diagram.
- Match (orally and in writing) situations, tape diagrams, and drawings that represent the same equal groups.
Required Preparation
- Create a set of cards from the blackline master for each group of 2.
Teacher Reflection Questions
How did connecting different representations of multiplication during the card sort support students in developing their understanding of multiplication?
