Your students will become junior math detectives as they hunt down the missing side of a rectangle by applying the area formula for rectangles. The only clues they have are the rectangle's area and the measure of one side.

Let your students explore different strategies to figure out the missing number in an equation. Use this lesson on its own or as a support lesson for Missing Numbers: Math Review.

In this lesson, students must become detectives to solve for the missing number in each subtraction problem. They will develop and use their powers of mathematical reasoning using number bonds to find differences.

Help your students fill in the missing links! With a focus on transitional words and conjunctions, your students will discover the links that will help them combine ideas in their writing.

Make math colorful! Teach your students to find the factors of a number using the factor rainbow strategy.

Let's solve multi-digit division problems! Students will feel more confident with their division than ever with this lesson that helps them practice dividing multi-digit numbers.

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.

Take your understanding of factors one step further! Use this lesson to classify factors as prime and composite numbers while creating factor trees.

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.

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

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.

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

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

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.

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

Help your students understand place values with this lesson that catches their interest using a story book. Students will go one to play a riddle game both in a group and individually.

Help students use a 100 chart while discovering patterns of one more. This fun lesson will help students find connects between numbers and gain fluency with numbers within 100.

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.

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.

In math, mistakes are welcome! This lesson helps your students identify and fix errors made while comparing three- to four-digit numbers. Teach the lesson on its own or as support to the lesson Let's Compare Whole Numbers!

Many students cringe when they see a subtraction problem with multiple zeros. The “Subtract One” strategy in this lesson involves reducing the top number by one to turn the 0 digits into 9’s and then adding the one back in at the end.

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.

Will one be left out? Students will practice creative problem solving as they strive to answer this question and determine whether a group is even or odd.

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.

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.
