Showing Results for two digit and regrouping

Guide students to use base ten blocks to solve two-digit by one-digit addition problems with regrouping. This lesson can be used independently or paired with the lesson Adding it All Up. 

Using Regrouping to Add

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.

Regrouping with Base-Ten Blocks

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.

Let's Build It! Two-Digit Addition

Do your students ever want to just hurry and finish their homework? Your students can use the number line jumping strategy to quickly add two-digit numbers and show their understanding of place value and expanded form in the process.

Let's Jump to Add Two-Digit Numbers

Who doesn’t like to spend money and plan parties? Students will subtract two-digit numbers as they calculate the remaining money for their party supplies. They will subtract in multiples of ten and focus on place value. 

Show Me the Money! Two-Digit Subtraction

What does it mean to expand a number? Use this lesson plan to help your students understand how to write the expanded form of two-digit numbers.

Let's Stretch the Values! Writing Two-Digit Numbers in Expanded Form

Can you break a ten? An everyday exchange of money can help students think about regrouping to subtract. Students will use bundled popsicle sticks to see how values grouped into tens can be regrouped into ones to allow us to subtract. 



Regrouping with Popsicle Sticks: Double-Digit Subtraction

In this lesson, students will learn how to add a one-digit number to a two-digit number. This will help students build upon the skills needed for regrouping larger numbers.

Adding it All Up

In this engaging, hands-on lesson, students solidify their understanding of place value by adding and regrouping two-digit numbers using M&Ms.

M&M Math

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.

Comparing Strategies for Three-Digit Addition

Make addition with regrouping easy with this lesson plan that makes the task a visual learning experience.

Addition with Regrouping Center

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. 

Thinking About Three-Digit Numbers

Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

Three-Digit Addition Strategies Review

Help your students subtract with confidence by sharing two different strategies. Use this lesson to build on students’ understanding of subtraction and to evaluate this key skill.

Subtraction with Regrouping

Double-digit trouble? No problem! Your students will practice their decomposing and regrouping skills in this lesson.

Double Trouble: Subtraction Practice

In this lesson, students will add three-digit numbers using expanded form addition and standard algorithm addition. They'll explain their answers and highlight the steps for each of the strategies.

Addition with Regrouping

Use this lesson to support students in learning how to write three-digit numbers as number names. This scaffolded EL lesson can be used alone or as a pre-lesson for All About Three-Digit Numbers.

Writing Three-Digit Number Names

Teach your students to confidently follow the steps of regrouping in subtraction problems. Use this as a stand alone lesson or alongside *Regrouping with Popsicle Sticks: Double-Digit Subtraction*.

Get Together to Regroup

Give your students a conceptual understanding of three-digit addition with this lesson focused on base-ten blocks and drawings. 

Three-Digit Addition with Base-Ten Models

Students will get a chance to use multiple methods to compare three-digit numbers. They will also get practice using greater than and less than symbols to show their answers. 

Comparing Three-Digit Numbers

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.

All About Three-Digit Numbers

Let students stretch their problem solving skills in this lesson that teaches them how to solve problems where one-digit numbers are multiplied by multiples of 10.

Multiplying One-Digit Numbers By 10

Teach your students to use an area model to solve multiplication problems with a two-digit factor.

Multiplication with Area Models

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.**

Base-Ten Block Sketches

Teach your students to use number lines as a strategy to multiply two single-digit factors.

Number Line Multiplication

Name that hero! In this lesson, your students will practice adding two digit numbers together. They will get more comfortable adding bigger numbers together, making it easier to add three digit numbers later on.

Math Heroes

Teach your students to use skip counting as a strategy to multiply two single-digit factors.

Skip Counting to Understand Multiplication

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.

Comparing Values

Help your students make sense of the greater than, less than and equal to in this interactive lesson! Your students will have opportunities to compare either two-digit or three-digit numbers.

Greater Than, Less Than, Equal To Game

Master rounding and estimating skills by having students challenge their classmates in the Make a Big Difference game. Roll three dice two times to arrive at two three-digit numbers. The largest difference wins!
