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.

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.

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.

Your students will go bonkers for bingo as they play this baffling multiplication game! Who will get five in a row first?

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

It’s time to learn a new strategy! Teach your students to use the partial quotients strategy to solve long division problems with one-digit divisors and no remainder.

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

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.

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.

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

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.

Teach your students to create equivalent fractions by multiplying by different fraction forms of 1 whole like 2/2 or 4/4. This lesson also includes drafts of area models.

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

In this lesson, your students will compare numbers to one thousand using place value charts and symbols. Your students will love practicing with numbers!

Students will have fun learning the Read, Draw, Write (RDW) strategy on two-step, mixed operation problems. First they will learn RDW, and then they will practice it in a game called Four in a Row.

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.

All fictional stories have story elements but they sure can differ between stories. In this lesson, students will compare and contrast the story elements of two fictional stories and document their findings in a graphic organizer.
