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.

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.
