Since working with food items is frowned upon, we use this as a small group snack activity, so that the children can nom up their M&Ms right after they’re done.
Sanitize your work surface as well, before and after each child!
At the link on the bottom of the page from www.makinglearningfun.com, there are two types of organizational charts available for M&M sorting. I print 3 of each because I like to have materials available for varying abilities. Also some children just need a visual to organize the M&Ms before they graph them, while others are just working on sorting, and others still can work on graphing and charting and discuss number patterns.
Print and laminate for shared use (we don’t use work sheets or printables at our center either…so they’ll just use it for discussion and share).
It’s up to the teacher to facilitate much of this discussion and is largely up to you how much the children take from it! So ask lots of questions and keep them interested and engaged before they nosh on their chocolates!
