## Stage 1: Factors 1, 2, 5, and 10

### Narrative

Students generate factors with a number cube and a spinner with the numbers 1, 2, 5, and 10. Students use a $$10 \times 10$$ grid.

Each group of students need a paperclip, a number cube and two different color writing utensils.

## Stage 2: Factors 1–5

### Narrative

Students generate factors with a number cube and a spinner with the numbers 1–5. Students use a $$15 \times 15$$ grid.

Each group of students need a paper clip, a number cube, and two different color writing utensils.

## Stage 3: Factors 1–10

### Narrative

Students generate factors with two spinners, one that shows 1–5 and one that shows 6–10. Students use a $$20 \times 20$$ grid.

Each group of students need two paper clips and two different color writing utensils.

## Stage 4: Whole Number and Fraction Factors

### Narrative

Students generate factors with a number cube and a spinner with fractions with denominators of 3, 6, or 12. Students use a $$24 \times 24$$ grid that represents 16 square units.

Students generate factors with a number cube and a spinner with the numbers $$\frac{1}{2}$$, $$\frac{1}{4}$$, $$\frac {1}{5}$$, $$\frac{1}{10}$$, $$\frac{1}{20}$$, and wild, where students can choose their own number. They find the products and fill a $$20 \times 20$$ grid that represents 1 square unit.
