Unit 1, Lesson 7
Sort Math Tools
Grade 1
Preparation
Lesson Narrative
In kindergarten, students sorted objects into given categories. In this lesson, students choose categories to sort math tools that they have used in previous lessons (pattern blocks, two-color counters, and inch tiles). Students explain how they sorted and how many are in each category.
Although math tools are suggested and described throughout the lesson, any small objects may be used that students can sort into two or more categories.
In Activity 3, students choose from center activities introduced in previous lessons, to practice counting up to 20 objects or adding and subtracting within 10.

NoneTeacher Reflection Questions
In kindergarten, students compared two- and three-dimensional shapes and used informal language to describe how they were alike and different. What informal language did students use to describe shapes today? How did the Collect and Display routine help students develop more language to describe objects?
