Reflections
Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson in a seven-part series.
Technical Sketching
Introduction — Surfaces and Edges
How different can 3-D and 2-D really be? An engineering resource provides an explanation about the importance of two-dimensional technical drawings. Several samples show how to create multi-view drawings from pictorials and...

Colour by Numbers–Image Representation
How do computers store and send images? Here's an activity that explains one way a computer can compress image information. Pupils decode run-length coding to produce a black and white image. Pairs then work together to code and...

Negative Scale Factor
Class members investigate the effect of a negative scale factor dilation on coordinate shapes as they watch a short video that shows an example of a geometric figure undergoing a dilation with a negative scale factor. Learners then try a...

Who Sends the Most Text Messages?
The way you use statistics can tell different stories about the same set of data. Here, learners use sets of data to determine which person sends the most text messages. They use random sampling to collect their data and calculate a...

Linking Algebra to Temperature
Learners convert between two units as they calculate the temperature. In this algebra lesson, students collect data on seasonal climate and create a graph. They make conjectures based on their data collection.

Linear Equations and Cell Phone Plans
Young scholars calculate the amount of minutes they get charged for each month. For this algebra lesson, students relate linear equations to talking on the phone and the cost to do so. They create graph to plot the cost and usage of the...

How Far Will It Roll?
Students construct a car with the longest roll using a ramp. They construct Lego cars, modify the wheel sizes and car configurations to evaluate which car design rolls the longest distance, develop a graph, and complete a worksheet.
