This I have, who has game includes a 25 card set, plus 3 blank cards to print and extend the game as much as desired.
Units covered include ounces, pounds, and tons.
I've also included a bonus set of custom made mustache pencil toppers! I like to have the kids write a "cheat sheet" on the back of the mustaches. They love to "wear" them while they play.
This game can be played whole class or in small groups. Instructions included!
This game can also be found bundled with my Customary Unit - Length and Capacity games!
