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.

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.

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.

Use this hands-on lesson to encourage collaboration amongst students as they review base-ten numerals, number names, and expanded form. This lesson can be used as a pre-lesson to Base Ten Block Party or as a stand-alone activity.

Expose your students to numerical sequencing and patterns with an interactive lesson that focuses on identifying, writing, and ordering numbers from 1-100. This lesson can be used alone or with the lesson plan Popping Numbers.

Use this lesson to support students in understanding the symbols used to record numbers. This lesson can be used alongside Comparing Three-Digit Numbers or as a standalone, scaffolded EL support lesson.

Get your little mathematicians excited with this fun lesson about comparing decimals. It features helpful review activities and a game that's sure to keep students engaged.

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.

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.

Use this lesson to support students in learning how to write three-digit numbers as number names. This scaffolded EL lesson can be used alone or as a pre-lesson for All About Three-Digit Numbers.

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.
