Kindergarten Mathematics Module 2, Topic B

children reading

The lessons of Topic B reiterate those of Topic A but with solid shapes. Lesson 6 begins with students finding solid shapes in their environment. They might find bottles of paint, tissue boxes, balls, or crayons, and describe their object to their neighbor using informal language. “My ball is round and it bounces!” “This tissue box has a lot of pointy corners.” Some students might even use the flat shape vocabulary they learned in Topic A to describe their solid shape. “There are a lot of rectangles on my tissue box, too.” Lesson 7 continues with learning the names of the solid shapes and focusing on their attributes. Students are asked to explain their thinking as they classify the solid shapes into categories. “I’m putting all the cubes and rectangular prisms together because they all have six sides.” “The spheres and the cylinders roll, they should go together.” Lesson 8 guides the students to use their new solid shape lexicon to communicate the position of solid shapes to each other. In this lesson, the students identify, name, and position shapes relative to each other.
