Person with fewest letters in last name keeps score. No whining and no writing on the sheet!

Partner Relay (One person is L(x) and the Other is R(x)Human Number Line (not on handout)Have the students arrange the cards (or themselves) from smallest to largestExample

Students can do this with groups creating three problemsProject Ideas (go to website for details)Dodecahedron Collage Graphing ProjectWater FountainModel Home
