Q1.
A factory has ordered 58 wheels for the small tempos that they make. Each tempo has 3 wheels. In how many tempos can they fix the wheels? Discuss your thinking in each step. Number of tempos is 58 ÷ 3. 30 wheels are needed for 10 tempos. _______ wheels are left. 15 wheels are needed for _______ tempos. _______ wheels are left. 9 wheels are needed for _______ tempos. _______ wheels are left. _______ wheels are needed for _______ tempos. _______ wheels are left. Can we make another tempo? How many total tempos can the factory make using the 58 wheels? ______
Answer
The 58 wheels, taken away in groups of 30, 15, 9 and 3.
The factory can make 19 tempos, and 1 wheel is left.
30 wheels are needed for 10 tempos. 28 wheels are left. 15 wheels are needed for 5 tempos. 13 wheels are left. 9 wheels are needed for 3 tempos. 4 wheels are left. 3 wheels are needed for 1 tempo. 1 wheel is left.
Total tempos = 10 + 5 + 3 + 1 = 19

Each step takes away a group of whole tempos.
Can we make another tempo? No. Only 1 wheel is left and a tempo needs 3.
Why it happens: Dividing 58 by 3 means asking how many groups of 3 fit inside 58. We pull out easy groups — 10 tempos, then 5, then 3, then 1 — and add them up.
