⭐️ Essential Key Concept ⭐️
C2.1 identify when symbols are being used as variables, and describe how they are being used
C2.2 determine what needs to be added to or subtracted from addition and subtraction expressions to make them equivalent
C2.3 identify and use equivalent relationships for whole numbers up to 100, in various contexts
F1 demonstrate an understanding of the value of Canadian currency
F1.1 identify different ways of representing the same amount of money up to Canadian 200¢ using various combinations of coins, and up to $200 using various combinations of $1 and $2 coins and $5, $10, $20, $50, and $100 bills
Mathematical Modelling is a key process expectation that connects across multiple strands. Opportunities to engage students in modelling may arise naturally within rich, real-world contexts — for example, in financial literacy (e.g., creating a budget), measurement (e.g., designing a garden space), or data (e.g., interpreting results from a student survey).
We recommend using open-ended tasks where students define problems, make decisions, and justify their thinking — even in informal ways — as early steps toward developing modelling skills.
See our Mathematical Modelling page for more information.

During this topic, pay attention to the students' ability to maintain positive motivation and perseverance.
Do students have strategies when they are stuck? (e.g. attempt or test out different approaches, use resources in the room, ask for help from a friend)
Are students open to learning from mistakes?
Do students recognize what is working well for them, and what might need to be changed?
