I love this activity to introduce our division unit each year! We use the text The Doorbell Rang by Pat Hutchins to discover division concepts like 'sharing,' 'equal groups,' and 'holders.'
This resource has everything you need to create a meaningful math activity...you just need the text!
lesson plan detailing the activity
activity sheet for students using academic vocabulary
printable 'plates' for activity
All you'll need is the cookie cereal!
