Examine the consequences of varying speed.  An engaging set of five problem sets challenges young mathematicians by targeting a different grade level from K-12. In the initial lesson, scholars make conclusions about the time it...

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.

Seven tens, plus five ones, equals 75. Five ones, plus seven tens, also equals 75. These are the types of equations learners are asked to make true in a worksheet with 11 unfinished equations.

Ride to success in understanding systems of equations. Scholars graph a system of equations on the cost of a subway and a taxi using an interactive. Using this graph allows users to answer some questions about the situation.  

Challenge your classes to design and market a new product. Collaborative groups use geometry skills to create packaging for their products. Finally, they plan a marketing strategy to present to a marketing specialist.

Solving a murder is like isolating a variable. Using a video on a murder mystery, the narrator introduces the idea of solving a literal equation for one variable. After solving several equations, the class comes up with a set of...

Bank on geometry to line up the shot. The resource asks the class to determine the location to bank a cue ball in a game of billiards. Using their knowledge, class members determine where to hit the bumper to make a shot and discuss...

All work and no play makes for a boring classroom! Bring back memories by analyzing the patterns of a tether ball. Given the dimensions of the ball, pole, and rope, young scholars must determine how many times the ball will wrap around...

Wearable devices have become more the norm than the exception. Learners analyze data from a sample device with a regression analysis in a helpful hands-on lesson. Their focus is to determine if there is a connection between temperature...

Learners won't have to dig themselves out of a hole thanks to an insightful video. Using the movie Holes as inspiration, individuals must determine the difference in the number of holes dug when digging with a shorter shovel. Because the...

You would probably do anything for your Nana, including fixing her mistakes! Nana provided the wrong ratio to mix red and white paint, and she didn't realize it until after she mixed the paint. Your class now needs to figure out how to...

You are what you eat, or so they say! After surveying family and friends on a week of eating habits, learners analyze the data for patterns. They compare different variables such as fats and cost, fats and calories, or fats and LDLs.
