Slide Content
1. ### Slide 1 - Parcc math example

• 3rd grade art teacher’s rectangular array
2. ### Slide 2 - Part a

• An art teacher will tile a section of the wall with painted tiles made by students in three art classes.

• An art teacher will tile a section of the wall with painted tiles made by students in three art classes.
• Class A made 18 tiles
• Class B made 14 tiles.
• Class C made 16 tiles.
• What is the total number of tiles that are to be used?
5. ### Slide 5 - Part b

• The grid shows how much wall space the art teacher can use. Use the grid to create a rectangular array showing how the art teacher might arrange the tiles on the wall.
• Each tile should be shown by one shaded box.
6. ### Slide 6 - Part c

• Andy created a rectangular array showing how he would place 56 small tiles on the wall. He placed 7 tiles in each row. He wrote a multiplication equation using R to stand for the number of rows he used.
• Write an equation using R that Andy could have written.
