Lesson 12

Count Images (Part 2)

The purpose of this lesson is for students to count to answer “how many” questions about groups of up to 20 images and keep track of images that have been counted.

In previous lessons, students counted groups of up to 20 objects and groups of up to 19 images arranged in lines, arrays, and on 10-frames. In this lesson, students count groups of up to 20 images arranged in lines, arrays, circles, and on 10-frames. Students use methods of keeping track of images that they have developed in previous lessons and units and may develop new methods, especially when counting images in circles. Students practice writing numbers 11–20 to represent quantities.

As you finish up this unit, reflect on the norms and activities that have supported each student in learning math. List ways you have seen each student grow as a young mathematician throughout this work. List ways you have seen yourself grow as a teacher. What will you continue to do and what will you improve upon in the next unit?
