Minnesota-China Connections:What Time Is It?
Students calculate the time difference between Beijing, China and their local community. They discuss how time difference affects intercultural communication.
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
One Size Fits All?
Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

Car Maze competition
Pupils 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.
Curated OER
Finding Your Stride Length
Students participate in an estimation activity to determine the length of a hallway or to estimate how many people can fit in the school stadium or gym.
Curated OER
RCX Car Line Graph
Students develop a line graph based on distances that an RCX car drives in specified amounts of time. They then are given a specific amount of time for the car to drive and be asked to extrapolate the car's distance from the graph.
Curated OER
The Price is Right, So Let's Make Change
Students estimate, calculate, and count back the amount of change needed from purchases made during small group activities.
Curated OER
Paper Planes
In this unit, 3rd graders investigate one variable to see if they can make a paper plane fly farther. They use scatter plots to establish a possible relationship between variables then use what they have found to make a paper plane to...

Guess My Piece -working with Legos
Students participate in guessing their partners' hidden Lego pieces from their verbal clues. They work in partners to accomplish their goals. They are meeting a variety of math standards by completing this lesson.
Curated OER
Estimation Lesson Plan
Students use four different computer estimation applets with several classroom estimation activities.

Houses
Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...
Curated OER
Worms and more
Students have early length experiences must develop an awareness of what length is, and of the range of words that can be used to discuss length. Young children usually begin by describing the size of objects as big and small. They...
