## Lesson Plans

Understanding the Equal Sign:

This lesson helps students to understand the meaning of the equal sign and to realize that one side of an equation must equal (balance) the other side of the equation.

Type: Lesson Plan

Skip Count by 5s:

Help the Third Little Pig skip count to 1,000 bricks in groups of 5. (Note students are not expected to count from 0-1,000 by 5s, but this activity allows them to experience counting within a variety of contexts between 0 and 1,000.)

Type: Lesson Plan

Bears Odd Bears Even:

In this lesson, "students use counters and cubes to classify and model numbers as even or odd." (from Beacon Learning Center).

## Virtual Manipulative

Pan Balance - Numbers:

This tool helps students better understand that equality is a relationship and not an operational command to "find the answer." The applet features a pan balance that allows the student to input each half of an equation in the pans, which responds to the numerical expression's value by raising, lowering or balancing.
