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.

Students put their understanding of one and 10 more to work as they write word problems for classmates to solve. This lesson plan can be used alone or with Picture Addition.

Students will learn how to find the actual value of three-digit numbers with this activity that has them use manipulatives to create the expanded form of a number.

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

Make multiplying by powers of ten more accessible to your students by focusing on patterns in the number of zeros!

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

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.

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.

Students will get plenty of practice counting and writing numbers to 30 as they compete to win this fun game! Use this scaffolded EL Support Lesson alone, or alongside the lesson plan I Spy Counting Practice.

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.

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.

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

Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.
