An estimate is a check, not a receipt
Choose and explain rounding or bounds, then recognise when an exact calculation is needed near a budget limit.
Choose one job
A
Four pretend kits cost $18 each, plus one $7 fee. The budget is $80.
B
Six pretend sets cost $17 each, plus one $9 fee. The budget is $110.
C
Eight pretend packs cost $23 each, plus one $12 fee. The budget is $200. Explain why rounding down to $170 is not enough to decide.
Make your own plan
Make/draw, talk/sign/point/dictate, type or use paper. Label what each quantity counts. Check your work and make a useful message for the organiser. Try one instruction at a time, a quiet place, a pause or larger pieces. A/B/C are choices, not labels for people.
