Matching cards work great to randomly group your students. Eliminate the problems of students choosing partners and groups. Now your students can quickly get into cooperative groups for work groups, games and activities.
Decide in advance how many groups of 2, 3 or 4 you will need and select those cards for grouping. Students choose cards and then wait for directions on how they will be grouped by graphics, letters, or numbers.
Cards come in both color and b/w. 53 pages
