Drawing Straws
Fourth graders examine the Triangle Inequality Theorem by investigating possible lengths of the sides of a triangle.
Curated OER
Technology vs. Nontechnology
Fourth graders determine the range, mean, median and mode using a computer spreadsheet. An identical set of calculations is done without using a computer. The results of each method are compared. They calculate the mode, median and range...

More Volume Please! Don't Be Dense!
Fifth graders determine volume and density through their knowledge of mass, volume and density.
Curated OER
Making Hypotheses
Fourth graders practice making hypotheses about what they believe occur as they perform an osmosis experiment in class. This experiment is designed to illustrate how important it is to make an accurate hypothesis.
Curated OER
The Water Detectives
Students collect water samples from designated sampling stations, and discuss water pollution. They analyze the water samples, record the data on a spreadsheet, and present the environmental water quality data to the class.
Curated OER
Hey! What Is Your Angle?
Fifth graders create and classify straight, right, acute and obtuse angles. In this clever lesson, 5th graders utilize pretzel sticks to form different types of angles. Best of all, they get to eat them at the end!

Speeding By The Numbers
Students determine speed by running or walking a given distance and dividing the distance by the time it took them to do so. They record their average speed and compare it with the speeds of other moving objects.
Curated OER
Arithmetic Artistry
Learners create a classroom quilt that illustrates the many unique ways that students use math skills.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
Curated OER
Dealing With Data
Students collect, organize, and display data using a bar graph, line graph, pie graph, or picture graph. They write a summary describing the data represented and compare the graph to another graph in the class.
Curated OER
The Proof Is in the Picture
Students select a geometric figure and find an example of the figure in their surroundings. They photograph the figure and write a proof to accompany it. They match photos to proofs.

Slicing Up Food Fractions
Second graders categorize, cut, and sort food items to explore fractions.
Curated OER
Toboggan Science
Students conduct toboggan time trials to investigate the variables that have the greatest effect on toboggan speed. In small groups, they develop a hypothesis to test and perform three trials on the toboggan run for each variable.
Curated OER
Lyrics Statistics
Students describe, analyze and generalize relationships, patterns, functions using words. symbols, variables, tables and graphs.
