Math: Find Area and Perimeter

Activity idea: Use the camera to identify triangles around your school. Then students will use the drawing tool to show lengths of the sides of triangles and add to find the perimeter. They can take another photo to draw the formula for area and use the microphone tool to narrate their reasoning.

Tip for Teachers/Students: Get creative with your triangles as they can be found all around your school. Try the gym, playground and areas around your classroom for student inspiration to complete their task of finding and explaining triangles. It will help as a teacher to first find a few triangles yourself that you can model whole group. Teachers can also use stock images so the whole class has the same image to describe as you first model the lesson before sending out your students.

Supports Common Core: CCSS.MATH.CONTENT.3.MD.C.6: Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units). CCSS.MATH.CONTENT.4.MD.A.3: Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor
