3rd grade "Mister Troll" activity

This week 3rd graders learned the song "Mister Troll" from One, Two, Three, Echo Me. Half the class plays various parts on instruments, and half the class waits for "Mister Troll" to say a color. If the students waiting are wearing that color they get to cross the troll's bridge. Once everyone has crossed the bridge the two groups switch and now those that were playing the instruments get to try and cross the troll's bridge.
