Help your students create a basis for future math classes with this lesson that teaches children about math expressions and how they can interpret them.

In this lesson, students explore absolute value with and without a number line, compare the absolute values of two numbers, and apply their understanding of absolute value to real-world contexts.

In this lesson, your students will measure the lengths of items and then make a line plot to show the measurement data. They will get hands-on by measuring and surveying the class.
