Learning objective
What this activity builds
Use the fixed center factor to find products and recover missing factors from known products.
Worked example
The center is 6. One sector shows a product of 42 with its inner factor missing. What belongs there?
7
Find the number of groups of 6 in 42: 42 ÷ 6 = 7, so 6 × 7 = 42.
Teaching notes
Make the practice count
- Have learners point back to the center before solving each sector.
- Pair a missing-product sector with a missing-factor sector from the same fact family.
