Dive deep into using base-ten blocks to solve two-digit subtraction problems with regrouping. This lesson can be used independently or in conjuction with the lesson Double Trouble: Subtraction 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.

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.

Help students gain a better understanding of three-digit numbers by providing students with opportunities to compare sets of three-digit numbers. Use as a stand-alone activity or alongside the lesson Building My Math Fluency.

Numbers are blooming! In this flower-themed lesson, students will create a piece of math artwork that will help them practice recognition of numbers through ten.
