Use this lesson to introduce composing and decomposing as part of your students’ addition and subtraction toolkits.

Number facts are related, just like families! Help students learn all about fact families while they make fact family trees!

Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

In this lesson, your students will learn how to buy items and use money to purchase items in the real world. You will set up a store for the students to learn about money.

Roll some dice to introduce the early concepts of associative and commutative properties in addition by composing and decomposing 10. Worksheets and a quiz are included!

Help your students use rulers in the classroom with this lesson! Encourage them to measure items around them using centimeters to understand shapes and sizes.

In this lesson, your students will measure the lengths of items and then make a line plot to show the measurement data. They will get hands-on by measuring and surveying the class.

Students will get to explore three-digit numbers through base-ten blocks and written form. Students will get plenty of practice identifying the place values of a number both individually and with the class.

Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.
