Regrouping with Popsicle Sticks: Double-Digit Subtraction

What exactly does the number 97 mean? How about 454? In this lesson, students explore how two-digit numbers are made up of tens and ones. Then they use this understanding to subtract numbers within 1000.

Break It Down

How are quadrilaterals connected? In this lesson, your students will learn about the relationship between quadrilaterals by drawing, defining, and labeling different ones.

Are You Connected to Me?

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

Dive into understanding place value by using place value disks to represent and compare numbers. 

Let’s Compare! Place Value Disks & Three-Digit Numbers

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

Are your students hungry for math? In this lesson, students pretend to order their favorite takeout foods with their classmates all while practicing rounding decimals so that they know what to expect when the bill comes!

Menu Math: Rounding Decimals

Help your students practice place value with this fun, hands-on base-ten block game. Neighborhood block teams compete to win points as they work together to show expanded numbers.

Base-Ten Block Party

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

Three-Digit Addition Strategies Review

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 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

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

Double Trouble: Subtraction Practice

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

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

Picture Addition

Students will gain fluency with adding multiples of ten in this hands-on lesson that builds number sense.

Ten Time

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

Your students will “hop their way” into understanding place value with this fun and active game! In this lesson, they will learn that changing the order of the digits in a number changes its value.

Place Value Hop

Teach your students to draw an array using base ten notation to solve multiplication problems with two two-digit factors.

Base Ten Arrays for Multi-Digit Multiplication

Use this lesson to introduce composing and decomposing as part of your students’ addition and subtraction toolkits.

Composing and Decomposing

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

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

This lesson will help students build an understanding of multiples as they learn how to subtract from multiples of 100!

Subtracting from Multiples of 100

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

Students will learn to convert metric units by applying concepts in word problems. Exercises and worksheets incorporate length (meters), and optional practice offers more instructions on mass (grams) and volume (liters).

Converting Metric Measurement in Word Problems

Every student can be a magician after this lesson in mentally adding and subtracting by 10. No previous magic training required!

Math Mind Magic

Fractions can be tricky, but looking at them visually can help your students understand them. This lesson will help students with equivalent fractions, number lines, and making real world connections.

Let's Play Equivalent Fractions!

Teach your students to ask and differentiate between recall questions and inferential questions. This lesson will help build a classroom culture around asking deep, inferential questions.
