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.

This Halloween-themed hundreds chart game has plenty of tricks and treats! Students will roll two dice to move up and down the chart to be the first to 100. Players will also recognize important number patterns as they move their marker.

In this lesson, students use cubes to build arrays to represent factor pairs of numbers within 100. They use this understanding to identify multiples as well.

Do you feel like your students are on a merry-go-round when it comes to rounding? This lesson will give your student control of the “ride” and give them tools to use when rounding.

Pop into place! This lessons builds your students' knowledge of numbers, their place value, and how to write them correctly.

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.
