Grade Three Mathematics
Students will develop an understanding of three general units: Numbers, Patterns and Relations, Shape and Space: Measurement & 3-D Shapes and 2-D objects.
Children’s early experiences shape what they imagine to be possible. Study after study has shown the value of exposing children with positive role models. Representation, including in the hours spent consuming media within the classroom, shape what they imagine to be possible for people who look like them, live where they live, or come from where they came from. Simply put, kids determine what they can be based on the examples around them. Therefore, we highly recommend you take 2-5 minutes everyday in your math class to introduce mathematicians of colour. We've made this easy for you by creating a presentation that you can use with a slide a day to showcase a new mathematician of diverse background. You could do this on a daily, weekly, bi-weekly or during a certain month. You could also make your own presentation and encourage this representation.
