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.

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.

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

Use this scaffolded EL lesson to teach students about money and the bills we use to pay for things. Use alongside Base Ten Money: Hundreds, Tens, and Ones or alone as an independent lesson.
