Investigate exponential growth and decay. A set of six activities has pupils collecting and researching data in a variety of situations involving exponential relationships. They model these situations with exponential functions and solve...

Cut-and-paste a great activity into your lesson plans. Scholars analyze real-world problems involving proportions. To change things up a bit they cut-and-paste quantities to create a proportion on their way to solving the problems.

Three activities make up an introductory lesson designed to create a strong foundation in comparing fractions to decimals and exploring and building decimal models. Pupils brainstorm and complete a Venn diagram to show how decimals and...

Investigate the properties of three-dimensional figures with this Arctic-themed math lesson plan. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-activity series supports children with learning how to measure the area of squares, rectangles, and...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry lesson. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden...

Using census data, the class finds the percentages of three diversity categories for four states and compare them. With the assistance of a 10 X 10 grid, pupils create visual representations of a comparison between two states on one...

Ready to field questions about slope fields? An article on AP® Calculus teaching methods describes how to teach about slope fields to solve differential equations. It gives some sample problems to consider with the class and how to...

Scholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson plan of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids....
