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

Your students will “hop their way” into understanding place value with this fun and active game! In this lesson, they will learn that changing the order of the digits in a number changes its value.

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.

What does it feel like to take 120 steps? In this lesson, students practice counting and completing word problems up to 120.

This lesson helps students review rounding to the nearest hundred. Your students will practice rounding using manipulatives.

Build familiarity with numbers from 1 to 120 with this fun game. This lesson can be used alone or with the lesson plan Then Came One.

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.
