These are revelations I had at the beginning of the year when I first started the Math Intensive with 6th graders.
You cannot combine unlike categories
Apples plus oranges can be fruit
Apples plus oranges cannot be applanges
You cannot add money + people

Today (Nov 4) I gave students a problem about students and buses and tickets to a play.
(3 busloads of students; 23 students and 3 adults per bus --- how many tickets are needed?)
Two students attempted to add buses + students to get to the number of tickets.
To think about:
What does "per" mean as a math operation?
