1. Quick Images: 15 min *Show image for a 1-5 seconds. *Dots are arranged in a way to help you determine how many there are. *Pay attention to how the dots are arranged.

3. How many total number of dots were there in all? Explain how you figured it out. How can we record your statements as equations ?

4. How were the dots arranged? How many dots were there in all? Sketch your mental picture of the arrangement & talk with your neighbor about what you saw. Then I will show you the picture again so that you can check.

5. Think about what FACTORS you see in the arrangement and to write equations that represent your thinking on paper.

8. Building Arrays !!! What are two factors I could use to build an ARRAY with 24 tiles?

9. When would you NOT USE an array and instead use a "bland" rectangle, called an unmarked array ?

10. What are the DIMENSIONS of each rectangular array ?

11. Work with a partner to find other arrays that have 24 tiles and draw the array in your spiral notebook, labeling the dimensions .

14. Have we found all possible arrays for 24? How do we know? What are the factors of 24?

15. When you label the dimensions of an array, you are naming MULTIPLICATION COMBINATIONS for the number. What are some other multiplication combinations you found for rectangles made with 24 tiles?

16. Who can list the factors of 24 in order from least to greatest? What are some multiples of 24? These are often confused! What are ways we can remember which are factors and which are multiples?

17. Number Puzzles: 1 Clue This number of tiles will make a rectangle that is 10 tiles wide. Work w/ a partner to think of a number that works and draw the rectangle and label the dimensions in your spiral notebook.

18. Draw student arrays and label the dimensions How many numbers are there that are multiples of 10?

19. S.A.B. pages 1 & 2 Yo u will work with a partner on pages 1 & 2, however, each student will complete your own pages. Unit 1 Table of Contents & S.A.B. pages 1 & 2 must stay in your binder behind your math spiral notebook. You may use centimeter grid paper and colored tiles, if needed.
