In this lesson, students write and evaluate algebraic expressions at specific values. They will also use variables to represent numbers and write expressions when solving a real-world or mathematical problem.

In this interactive math game, students will learn division facts while brushing the teeth of crocodiles. Students can choose from two different levels, easy and super. Then within each level they can choose from six different fact levels to play. Once they complete the game they can play again.

Students will learn how to use tricks to master multiplication facts. Students will be introduced to only 15 facts they must know to master multiplication facts through 9X11 with the prerequisite that they know the 0's,2's,5's,10's, and 11's.

In this lesson, students will estimate capacity and the relationship between several unusally shaped containers. They will verify relationships, express the relationship using variables, and apply the expressions to determine equivalent portions for each standard unit.

Interactive Resource allows the student to practice and learn division step by step using this long division activity.

This single player game helps students develop an understanding of the partial quotient strategy for division. It can also help students develop and understanding of division with and without remainders.

These Tasks are from Tools4NCTeachers. These Tasks align to 4.NBT.6. They are remixable.

These two lessons are from Tools4NCTeachers. In these lessons, students model and discuss the reasoning behind the partial quotients method of division. This is remixable.

In this lesson, students encounter a situation in which they must solve for the value of a variable. The equations are in the form of p = qx, in which q, x, and p are all whole number values. This CYBERCHASE activity is motivated by an episode in which the CyberSquad plays a game against Hacker to catch enough "gleamers" to power up the Cyberspace ship. If they win, they get the Encryptor Chip. But first, they must figure out the relationship between gleamers and power glows.
