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.

Activate your students' observational skills by having them analyze a chart of the powers of ten! Use this lesson on its own or as support to the lesson Powers of 10.

Teach your students to recognize patterns of zeros when multiplying by powers of 10 with exponents.

Build on students' understanding of the power of ten within multiplication to understand its effect within division. Use this as a standalone lesson or as support to the lesson Dividing Decimals by Powers of 10.

Make multiplying by powers of ten more accessible to your students by focusing on patterns in the number of zeros!

Roll some dice to introduce the early concepts of associative and commutative properties in addition by composing and decomposing 10. Worksheets and a quiz are included!

Help students use two strategies that will help them figure out which three-digit number is greater than, less than, or equal to another three-digit number. Use on its own or with Let's Compare! Place Value Disks & Three-Digit Numbers.

Use this lesson to familiarize students with the place value of each digit within a three-digit number, along with practicing the written form of three-digit numbers. Use prior to teaching Place Value Hop or as a stand alone activity.

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.

Your students will be able to divide decimal numbers by powers of 10 and explain decimal placement patterns in the quotient.

Students put their understanding of one and 10 more to work as they write word problems for classmates to solve. This lesson plan can be used alone or with Picture Addition.

Support your students' understanding of word problems as they invent strategies to add three addends in any order. Use this scaffolded EL lesson plan alone or with How'd You Get that Many?

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.

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.

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.

Do your students understand the power of 10? This lesson will allow your students to see the utility of the power of 10 in mathematics and come to a concrete conclusion of how 10 impacts the value of mathematical equations.

With this pastry themed lesson, your students will apply addition strategies to solve two-step, three-digit addition word problems. Finding the solutions will be sweet!

Get your students comfortable with discussing multiple strategies to solve subtraction problems with this lesson on two- and three-digit subtraction. It may be taught independently or as support for the lesson Subtraction with Regrouping.
