Small-group support
A coefficient multiplies the whole grouped value.
Evaluate 4(x + 3) when x = 2.
Parentheses group a sum into one value. The coefficient multiplies that whole value, not only the variable.
Problem 1 of 4. A short entry task, a model, guided examples, then a new independent try. Frames are optional.
Evaluate 4(x + 3) when x = 2.
Support frame: (2 + 3) × 4
