TOOTHPICKS AND TILES Cruz, Sophia, and Savanna are using toothpicks and tiles to describe the attributes of the shapes below. Cruz made a pattern and told the girls the number of tiles he used. Then Sophia and Savanna each tried to be the first to see who could call out how many toothpicks, or units of length, were on the outside. a. Cruz made the tile pattern shown at right and said, "There are six tiles." Savanna quickly said, "There are ten toothpicks." Copy the tile pattern on your paper and show where Savanna counted the 10 toothpicks. Justify your answer with words, numbers, or pictures.

b. Cruz made up a new pattern, shown at right, but he ran out of toothpicks. How would you describe this shape using toothpicks and tiles?

c. Get a set of tiles from your teacher and work with your team to: Make a pattern so that there are four more toothpicks than tiles. Draw your tile pattern on your paper. Label the number of toothpicks and tiles on your drawing. Is there more than one answer?​
