Lesson Purpose
The purpose of this lesson is for students to practice working with data and adding and subtracting within 10.
Lesson Narrative
Students learn Stage 1 of the Sort and Display center. Students sort 10–20 objects into two or three categories and represent how they sorted. Students show their representation to a partner and ask questions that can be answered about their collection of objects. Students then choose from other centers introduced in a previous section. This lesson provides the opportunity to formatively assess how students add and subtract within 10.
- Represent a collection of sorted shapes. Ask (orally) questions that can be answered about the quantities in the representation.
- Trabajemos con datos y practiquemos sumar y restar.
