The activity today is based on the book, Spaghetti and Meatballs for All by Marilyn Burns. The book presents several situations that require students to create expressions to determine how to arrange seating for a growing group of people. The book is lively and we will stop at different places to discuss the arrangement and how the expressions change. Students will get to think about and discuss the differences in the expressions they create. When we finish the story, the goal is that students will see that the original arrangement was the best way to seat everybody. That will become obvious as they move through the story.
We will stop to create an expression and discuss the arrangement at the following places in the story:
- Page 7 (each table has 4 place settings)
- Page 8 (two tables are pushed together)
- Page 9 (push two more tables together)
- Page 11 (push two more tables together for a total of 6)
- Page 12 (push two more table together for a total of 8)
- Page 15 (two groups of four tables)
- Page 19 (push 8 tables together to form one long line)
- Page 22 (divide the one long line into two equal lines)
- Page 23 (make the two long lines into 4 pairs of tables)
- Page 29 (divide the four pairs of tables into 8 single tables)

To end the class today, students will respond to a prompt that has them apply what we did in class today to a new problem situation.
PROMPT: Create an arrangement to seat 30 kids in our class if we want students in groups of four. Write an expression that represents this arrangement.
