….or another way to look at factor pairs
Suppose you want to rent a space that is 12 square yards. Use 12 square tiles to represent the 12 square yards. Find all the possible ways that the renter can arrange the squares. Copy each rectangle into your spiral or on your grid paper.
1 x 12
2 x 6
3 x 4
Find all of the dimensions for rectangles that would provide the new area. Draw these in your spiral or on your grid paper.
1 x 16
2 x 8
4 x 4
Which numbers have the most rectangles? What kind of numbers?
Which numbers have the least rectangles? What kind of numbers are these?
What numbers have squares on their posters?
If you know the rectangles you can make for a number, how can you use this information to list the factors of the number?
Write a description, with examples, of numbers that have the given factors:
I am thinking of a number…..It is larger than 12 and smaller than 40 and has exactly three factors.
What is my number?
