Freshen up on your understanding of division word problems with long division and one-digit divisors! Use this lesson to help students identify key division terms and solve word problems.

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.

Let’s get reading and writing! In this lesson, students learn to form and recognize regular plural nouns. But the fun doesn’t stop there. Students will work with counting collections to write sentences about the objects they count.

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.

Get your students excited about money! Have them make connections between their prior knowledge of base-ten numerals and one, ten, and hundred dollar bills.

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

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

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

Start your students on subtracting three-digit numbers with this lesson that breaks the problems down by place values!

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.

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.
