Here's a card game that'll help your students bone up on their skeletal system knowledge. (Someone slap me.) BONEYARD includes a total of 60 cards: 30 term cards and 30 definition/diagram cards. Players take turns flipping over two cards to see if they match. The player with the most pairs at the end of the game wins!
I designed this game for my multi-age elementary classroom, but it's appropriate for middle/high school students, too. Minimal prep work required: just print, cut, and go. It would make a great center or small group activity, and you won't even have to work your fingers to the bone to plan it. (I'm done, I'm done, I promise.)
