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.

Extend your students' understanding of data by asking them to consider real-world problems about data collection and graphs.

Dive deep into word problems with this lesson that teaches students to sketch base-ten blocks to add multiples of 10 and two-digit numbers. Use alone or with the lesson plan Let's Build It! Two-Digit Addition.

Keep students engaged and help them practice their counting fluency with this fun, game-based lesson. Students count and work with each other to create the classroom’s longest number snake. Who will be the winner?

This nifty lesson helps kinesthetic learners reinforce their knowledge of the commutative property. Students will love the challenge of matching equations with their fact families.

It's about time to learn about time! Your students will interact with a class made clock and roll the dice to 'make up' a time. But they better know their hour and minute hands apart to find success in this lesson!

Double dominoes! Get your students excited to add with dominoes and playing cards. This lesson is a fun way to help your students continue to learn to add.

In this engaging, hands-on lesson, students solidify their understanding of place value by adding and regrouping two-digit numbers using M&Ms.

Students will get plenty of practice composing tens with ten frames to add to 20! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Scavenger Hunt Addition lesson.
