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 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 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.

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

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.

Pop into place! This lessons builds your students' knowledge of numbers, their place value, and how to write them correctly.

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

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

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.

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.

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.

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.

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.

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.

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.
