TWISTERTWISTER
TWISTERTWISTER Directions: 1)Each student picks a circle with a color (red, blue, green, yellow) from a bag. 2)The teacher spins the spinner (either on Smartboard or homemade) and a color is revealed. 3)The teacher reads the first word of that color (yellow 1). Each yellow student has two minutes to write a definition of that word. 4)The teacher collects the definitions and reads them aloud without saying the student’s name. 5)The rest of the class votes on the best definition. The students get a point for each vote they get. 6)The students with the most votes after all words have been read is the winner.
