Adding and Subtracting Rational Expressions
There's a fine line between a numerator and a denominator! Learners find common denominators in order to add and subtract rational expressions. Examples include addition, subtraction, and complex fractions.

Multiplying and Dividing Rational Expressions
Five out of four people have trouble with fractions! After comparing simplifying fractions to simplifying rational expressions, pupils use the same principles to multiply and divide rational expressions.

One Size Fits All, Part 1
Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Cross Section and Slope
Students draw cross sections of given contour maps. In this math lesson, students interpret the different symbols used in the map. They determine slope and steepness through direct measurement.

How Do You Measure Up?
Students measure their body. In this measurement lesson plan, students use a string to measure their height and the circumference of their head. They record this information on the worksheet provided and answer questions as a group.

Finding Patterns in Fractals
Students discover patterns and sequences. They use a website to explore patterns and fractals. Students share their discovery of fractals and their patterns with the class. They develop a list of patterns used in everyday life.
