Raindrops are falling in this weather-themed math lesson! Students will manipulate raindrops and discover that raindrops can be counted in the same order, even when they are arranged in different ways.

Introduce place value to your emerging mathematicians while focusing on the numbers 11–20. In this lesson, students will practice separating teen numbers into 10 ones and some additional ones using unifix cubes and ten frames.

Students will get plenty of practice composing tens with ten frames to add to 20! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Scavenger Hunt Addition lesson.
