Can everybody have a partner?

Figure out how many people are here today as a class. (Think about who is not here and work backwards from 20. Double-check by counting all. Perhaps put children in groups of ten and extras to be sure.) Have them solve if everyone can have a partner on paper.



Return to share: solve the problem on the rug per a student's suggestion of how. (For example have students partner up to see if they all have a partner, or use cubes). Talk about how any students there are, how many //pairs// of students there are (go over the word //pair// and talk about things that come in pairs), and whether these are equal groups.
