A student has copied the numbers from this problem but has not decided what to find: "A sequence starts at 40 and decreases by 6 each step. Which term number has a value of 10?" Which support prompt is most helpful?
A
Say, "Write down a starting value of 40, a decrease of 6 each step, and a target value of 10, then calculate first; the unit can be added later."
B
Before choosing an operation, ask the student to define the unknown, note the known quantities, and name the unit.
C
Prompt, "Should the variable stand for the amount of decrease because that detail is already mentioned?"
D
Ask, "Can we use term number as the answer without deciding which quantity is missing?"
