Calculating the Shortest Distance Between Two Points
Ninth graders calculate the distance between two points.
Curated OER
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
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Bill's Badge
Learners explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on learners.
Curated OER
Fun Ideas for Getting A-Round in Math CIRCLES
Students see circles in real life and have fun with them
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...
Curated OER
Make Your Own Shape Puzzles
Students create their own shape puzzles. They practice putting puzzle pieces together so they fit correctly. They classify and sort the different shapes as they finish the puzzle.
