I Have aFriend Who
In this secondary mathematics worksheet, high schoolers determine the solution to a riddle involving words. The solution requires a non-traditional mathematics solution. The one page worksheet contains one problem with the solution.
Curated OER
Art Class, Variation 1
Student statisticians calculate ratios to determine how many shades of green were mixed by Ms. Baca's art class. They graph the number of blue parts against the number of yellow parts for each combination and discover that some produce...

How Does Water Cool?
How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.
