Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

Prepare to accelerate your Android. Pupils prep for the upcoming activity in this third installment of a four-part series. The lesson plan progresses nicely by first introducing different types of acceleration to the class. The teacher...

The bounce of a golf ball changes the result in golf, mini golf—and a great math activity. Scholars graph the height of golf ball bounces before finding a line of best fit. They analyze their own data and the results of others to better...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

What's the best way to pay for a car? Should I buy used or new? Can I realistically afford a car? Pupils discover the ins and outs of buying a car, from how to shop for car insurance to the advantages and...

This is great go-to activity for those spring or fall days when the weather beckons your geometry class outside. Learners start with a small tree, devising strategies to accurately estimate the leaf count. They must then tackle the...

The slider feature on Desmos excellently shows how graphs change based on different variable values. Learners look at two similar rational functions and compare and discuss what happens when the numbers go from positive to zero to...

First angle measures, now segment lengths. High schoolers first measure segments formed by secants that intersect interior to a circle, secants that intersect exterior to a circle, and a secant and a tangent that intersect exterior to a...

The Pythagorean Theorem makes an appearance yet again in this lesson on polynomial identities. Learners prove a method for finding Pythagorean triples by applying the difference of squares identity. 

Show how exponential growth can look linear. Pupils come to understand the importance of looking at the entire picture as they compare the US population to the world population. Initially, the populations look linear with the same rate...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

The 19th installment in a 25-part series builds upon the sampling from the previous unit and takes a larger sample. Pupils compare the dot plots of sample means using two different sample sizes to find which one has the better variability.

Your pupils may believe that you and their parents are the oldest things in the universe, but surprise! There are elements of the universe that are even older. Elementary scientists create a class timeline to demonstrate the...

Put those numbers to work by completing a statistical study! Pupils finish the last two steps in a statistical study by summarizing data with displays and numerical summaries. Individuals use the summaries to answer the statistical...

An interactive lesson helps individuals learn to graph inequalities in two variables. Scholars can adjust the interactive to present the inequalities in standard or slope-intercept form.

What a big job for such a small particle. Young scientists learn about the role of nanoparticles in catalytic converters for cars. They conduct an experiment to create alginate-MnO2 catalytic spheres. 

Learners identify the mean and variance. In this statistics lesson, students calculate the population variance using the N as a divisor. They draw the relationship of dividing by N and N-1.

Students identify, describe, count, tally, and graph life found in one square foot of land.

Students investigate the Sierpinski triangle and calculate the ratio and area of the triangle. In this fractals lesson plan, students calculate parts of a Sierpincki triangle. They use Google Earth to help them construct the different...

Young scholars investigate pH levels in bodies of water and experiment with acid/base reactions. In this water and pH lesson plan, students observe changes in pH levels of a sample solution and observe a Bronsted-Lowry reaction. Young...

Learners find the volume under a curve using the washer method. In this calculus instructional activity, students investigate solids and calculate the volume of an object rotation using the washer method. They investigate solids...

Students investigate the economics of starting a business in this series of lessons. They role play parts of a business organization that sells paper airplanes making decisions based on calculations to make the most profitable organization.

Students brainstorm reasons to save money, investigate impact of saving regularly using interactive, on-line calculators, explain how compounding interest affects savings, explore different strategies for saving money, and write personal...

Pupils investigate the formulas for volumes of various solids using the Ti-89 calculator. The instructional activity focuses on the keying sequences necessary to embed the required volume formula in a program which is then used in the...
