Understanding Probability
Young scholars investigate probability. They will define probability as the likelihood of an event occurring. Then, they determine the probability of sitting in a particular seat on a plane. They also set up ratios of various seating...

Translations
Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.
National Arts Centre
Scavenger Hunt
Young theatre artists engage in a scavenger hunt to acquaint themselves with set design. The challenge is to search the site and match a separate maquette with each of the 24 clues.

Properties of Area
What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Problem Solving Using Pattern Blocks
Students use pattern blocks to create a figure that is described to them and establish a pattern based on the description of the geometric figure. In this pattern blocks lesson plan, students fill out shape and fraction worksheets.

Why Does SSS Work?
While it may seem incredibly obvious to the geometry student that congruent sides make congruent triangles, the proving of this by definition actually takes a bit of work. This exercise steps the class through this kind of proof by...

Target Earth
Space scientists use water displacement to determine the mass of a cubic centimeter mini meteorite, and then use it as a small-scale representative of an asteroid. They figure out the orbital velocity of an asteroid. Then they use a...

Polygons
In this polygons worksheet, 10th graders identify and define both a polygon and a convex polygon and then, they apply two theorems that involve the interior and exterior angles of a convex polygon. First, they find the sum of the...
Curated OER
Reflection
In this math activity, students practice their skills in constructing reflections of shapes that are on a grid. This activity has 13 problems for the students to solve, and includes an answer sheet.
Curated OER
Dilations and Similarity
For this dilations and similarity worksheet, pupils solve 10 different problems that include various dilations. First, they determine the scale factor of dilations found in the illustrated graphs. Then, everyone determines the...

Shoelace Algorithm
In this shoelace algorithm learning exercise, students determine the area of a triangle when given the coordinates of the vertices. They determine the area of a quadrilateral. Students find the average of the x and y coordinates.
Curated OER
Simple Machines
Students investigate simple machines. In this simple machines lesson, students explore how tools increase productivity and make life easier. Students experiment with simple tools and discover the parts of each tool.

What Shape Am I?
First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...
Curated OER
Transformations: Translations
Learners perform transformations and translations using polygons. In this geometry instructional activity, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
Curated OER
Graphing Data
Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They calculate the volume, area and perimeters of the shapes created on a coordinate plane.
Curated OER
Transformations: Reflections
Young scholars perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.
