- 3. Let’sTry it! How many cubes are in the rectangle? What are factors of 16? Can you make another rectangle with 16 cubes?
- 4. Explore Create as many rectangles for the numbers 2 to 20. Create aT-chart and fill in all the factors
- 5. Connect Number Factors 2 1,2 3 1,3 4 1,2,4 5 6 7 8 9 10
- 6. Connect How do you know you have found all the rectangles for each number? What are the factors of 5? How do you know? (Make a rectangle with 5 tiles) How many rectangles do you think you will be able to make with 11 tiles?
- 7. Connect Suppose you have 23 tiles.You can only make one rectangle because factors of 23 are only 1 and 23. A number that has only two factors: 1 and itself is called a PRIME NUMBER. Suppose you have 24 tiles.You can make more than on rectangle because the factors of 24 are 1,2,3,4,6,8,12, and 24. A number that has more than two factors is called a COMPOSITE NUMBER.
