Indicators for this outcome
| The following indicators may be used to determine whether students have met the corresponding outcome. | |
| (a) |
Model a multiplication problem (concretely or symbolically) using the distributive property (e.g., 8 × 365 = (8 × 300) + (8 × 60) + (8 × 5)). |
| (b) |
Use concrete materials, such as base ten blocks or their pictorial representations, to represent multiplication and record the process symbolically. |
| (c) |
Create and solve a multiplication problem that is limited to a 2- or 3-digit number times a 1-digit number. |
| (d) |
Estimate a product using a personal strategy (e.g., 2 × 243 is close to or a little more than 2 × 200, or close to or a little less than 2 × 250). |
| (e) |
Model and solve a multiplication problem using an array, and record the process. |
| (f) |
Solve a multiplication problem and explain the strategies or processes used. |
