Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.

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.

Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

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.

Geometry meets data in this fun lesson! Students will build a design using pattern blocks and then graph the number of each shape used. This scaffolded EL lesson can be used alone or alongside Graphing Colored Counters.

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.

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

Students will learn how to find the actual value of three-digit numbers with this activity that has them use manipulatives to create the expanded form of a number.

This lesson helps students develop an ability to compare and contrast as they explore two strategies to solve three-digit addition problems. This EL Math lesson can be used alone or alongside Three-Digit Addition Strategies Review.

Students will explore geometric shapes by creating a painting of a trapezoid.
