Math Essentials 11 Desmos Activity Collection - A collection of online student Desmos activities organized by unit.
D1 demonstrate an understanding of the concept of perimeter and area
D2 calculate perimeter and area
D3 estimate perimeter and area using estimation strategies
D4 use perimeter and area to solve a variety of real world problems
D5 demonstrate an understanding of volume and surface area
D6 calculate surface area and volume of rectangular prisms and cylinders
D7 use surface area and volume to solve real world problems
D8 estimate the volume and surface area using estimation strategies
D9 calculate scale factors in 2-D scale diagrams and 3-D scale models; understand the relationship among the scale factor and the related change in area or volume
E1 understand the meaning and use of square root numbers when determining the dimensions (sides) of a square
E2 understand and apply the Pythagorean Theorem
E3 find the missing side measure in a right angle triangle
E4 create 2-D scale diagrams and 3-D scale models

Course materials from eLearningOntario - These materials have been shared to support students.
Area of 2D Shapes - Some great activities for finding the area of 2D shapes.
R2D2 Post-its 3 Act Task - Post it notes are placed on a bulletin board in the shape of R2D2. Ask students to estimate and then calculate the surface area of the bulletin board to find the total number of post-it notes used.
Coin Carpet 3 Act Task - If you were going to carpet the room with a single kind of Canadian coin, which would be the cheapest option? If you could use any coin currently in circulation in the world, what would you use? Some extra questions: Design a pattern using 2 or 3 different coins to carpet the floor in the classroom and determine the cost. Would coins make a good floor material?
Design a Flag - Read the article from Wired about Redesign SF's suck-tastic Flag. Or watch Roman Mars' TED talk about flag design. Have students design their own flag for your school. Perhaps someone at the school could actually sew up the best flag for the school. You could scale it up from the drawing to actual size. How much would the material cost to create the real flag?
File Cabinet l - How many post-it notes will it take to completely cover a tall file cabinet?
Going Round in Circles - Compare the height of a water bottle to its circumference. Most students will say the circumference is shorter than the height of the water bottle.
CEMC Courseware Lesson 1: Areas of Parallelograms, Triangles, and Trapezoids - The Centre for Education in Mathematics and Computing (CEMC) has developed online mathematics courseware.
CEMC Courseware Lesson 1: The Pythagorean Theorem - The Centre for Education in Mathematics and Computing (CEMC) has developed online mathematics courseware.
Marcellus the Giant Desmos Activity - This activity will help your students understand the definition of a proportional relationship. They'll create a giant and then make sure all of his features are proportional. They'll see the representation of his proportions on a graph and manipulate the graph to see the giant change dynamically.
Taco Truck Desmos Activity - In this activity, students use the Pythagorean theorem as a tool to solve problems involving diagonal distances. In a quick prelude, students reason with the Pythagorean theorem and with rates in a situation that they may encounter in their daily lives: taking a shortcut to save time. Students then determine the best path to a taco truck from a spot on the beach. The activity culminates in a class-wide race!
