Outcomes

7.C1.1

Identify and compare a variety of repeating, growing, and shrinking patterns, including patterns found in real-life contexts, and compare linear growing patterns on the basis of their constant rates and initial values.

7.C1.2

Create and translate repeating, growing, and shrinking patterns involving whole numbers and decimal numbers using various representations, including algebraic expressions and equations for linear growing patterns.

7.C1.3

Determine pattern rules and use them to extend patterns, make and justify predictions, and identify missing elements in repeating, growing, and shrinking patterns involving whole numbers and decimal numbers, and use algebraic representations of the pattern rules to solve for unknown values in linear growing patterns.

7.C1.4

Create and describe patterns to illustrate relationships among integers.

7.C4

Apply the process of mathematical modelling to represent, analyse, make predictions, and provide insight into real-life situations.
