Tile Activity . Where in your figure do you see the numbers in the math sentence? 1 2 3 4 5 6 7 8 3 9 10 11 12 4
Tile Activity . Where in your figure do you see the numbers in the math sentence? 1 2 3 4 We say that the numbers 3 and 4 are factors of 12. the number 12 is a multiple of 3 and a multiple of 4. 5 6 7 8 3 9 10 11 12 4
Tile Activity • Can you write a division sentence about your rectangle? • Where are the factors and multiples in your number sentence?
Tile Activity • What other rectangle can you make with 12 tiles? • What factors and multiples does your new rectangle illustrate?
Tile Activity • Using your 12 tiles make a rectangle with a length of 7. • Does it work? • Is 7 a factor of 12? • Is 12 a multiple of 7? • Try use your 12 tiles to make a rectangle with a length of 5. Do you think it will work? Why?
Tile Activity • What are ALL the rectangles you can make with 12 tiles? • What are ALL the factors of 12?
Tile Activity • On another day, do a similar activity with 20 tiles, 24, 30, 36, 48. Try the same activity with 13 tiles.
