Curated OER
Rep Tiles
Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
Curated OER
That's So Square
Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.
Curated OER
Perimeter
Students examine the concept of perimeter. Students calculate the perimeter of a random shape on a grid. Students develop a better understanding of the concept of perimeter. Students calculate the perimeter of shapes.
Curated OER
Saving Money Through Mathematics
Third graders discuss light sources and collect data about energy sources. They compare data and create a multiple line graph showing energy used by light sources for each student in the group. They present their graphs and write a...
Curated OER
Car Maze competition
Students use graphs to calibrate an RCX car. They must then program the car to traverse a maze using their calibrations
Curated OER
The Home Stretch
Students read the novel Stone Fox by John Reynold Gardiner. Using Lego RCX units, students build and program sleds to re-enact the "home stretch" of the National Dog Sled Race.
