o equations:
number of tiles = 2 × (position number) + 3 or
T = 2p + 3
or
NumTiles = 2*PosNum + 3
Instructional Tips
Teachers can:
• ground the learning for this expectation in real-life examples and contexts that are relevant to students;
• provide students with opportunities to use concrete materials (e.g., colour tiles, interlocking cubes, cups, pine cones, beads), digital tools, and coding to represent linear relations;
• support students in developing ways to determine the rate of change and the initial value in each of the various representations;
• provide students with opportunities to make connections between representations by providing them with one or two representations and supporting them in generating the others;
• facilitate a discussion about which representations are most helpful for various purposes, including making and reflecting on both near and far predictions;
