In this lesson, your students will use visual and hands-on strategies to divide whole numbers with remainders.

Your fourth graders will not only have fun creating and playing an equivalent fractions memory game in this interactive lesson, they will also become much stronger mathemeticians in the process.

Word problems present an additional challenge for English learners. This division lesson gives them a concrete strategy to decipher word problems. Teach it on its own or prior to teaching Division Word Problems.

Teach your students to subtract mixed numbers with like denominators using the strategy of decomposition. This strategy helps students to manipulate and break down numbers to help them solve tricky subtraction problems.

Sometimes authors choose to describe their setting for readers to imagine, but don't actually tell them where the story is set! In this lesson, students will learn to deduce settings from context.

This lesson helps your students become confident mathematicians when it comes to representing fractions visually in a variety of ways. Use this lesson as a pre-lesson to Fraction Hunt or teach it independently.

Which number doesn't belong? This lesson requires students to think critically as they determine which number is not a factor of a particular number. Teach it on its own or as support for the lesson Factors Over the Rainbow.

Empower students to think like mathematicians by having them create word problems related to subtracting mixed numbers. Use this lesson on its own or as support to the lesson Subtracting Mixed Numbers Using the Decomposition Strategy.

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.

Teach your students to add and subtract fractions with like denominators using a strategy that works for both operations: converting mixed numbers into improper fractions and back again!

Teach your students to find the perimeter of polygons using real world examples. They will make polygon pictures using tangrams and practice finding the perimeters of the polygons in their masterpieces.
