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.

With this lesson, your students will see how the order of the factors does not affect the product in a multiplication expression. Use this on its own or alongside You're On a Roll! Practicing Multiplication Facts.

Why make things harder on ourselves? Teach your students to decompose numbers to make math easier! Use this as a stand alone lesson or a pre-lesson for Decompose to Multiply: 6, 7, 8, and 9.
