## Grade Four Mathematics

Students will develop an understanding of four general units: Numbers, Patterns and Relations, Shape and Space; Measurement and 3-D/2-D objects, Statistics and Probability.

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.

- 3a. Demonstrate an understanding of addition of numbers with answers to 10 000 and their corresponding subtractions by using personal strategies/ problem solving context**Suggested use:**- Use to inform teaching on the abacus and different number systems

**PATTERNS AND RELATIONSHIPS**

____**Common Core and Islamic Art**

Document that lays out a lesson plan about the mathematics involved in Islamic design. The document makes a good connection to math. Originally, the document is linked to US math curriculum, but does intersect with lessons on geometry and pattern design in the Alberta curriculum.

**Curriculum connection:**- 1b. Identify and describe patterns found in tables and charts

- 2b. Translate among different representations of a pattern such as a table or a chart or concrete materials**Suggested use:**- Math to art curricular connection; use as a resource to have students incorporate Islamic design into a design project, such as creating a tile design

**SHAPE AND SPACE: 2D SHAPES AND 3D OBJECTS**

____**The complex geometry of Islamic design**

Video explaining the geometric principles behind the Islamic designs seen around the world.

**Curriculum connection:**- 3d. Demonstrate an understanding of area of regular and irregular 2-D shapes

- 2f. Demonstrate an understanding of line symmetry by: identifying symmetrical 2-D shapes/ creating symmetrical 2-D shapes/ drawing one or more lines of symmetry in a 2-D shape**Suggested use:**- Use to identify how each pattern can be translated, reflected and rotated to create different patterns**Accessibility:**- Closed captioning available on video
