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

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.

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.

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.

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.

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.

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.

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.

Shape up your students' understanding of geometrical attributes with this hands-on math lesson. Students will gain a better understanding of how to describe a shape by the number of edges and vertices it has, rather than by its name.

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