My students just love playing a game that I call "Eggs in the Basket". This is a super fun way to practice decomposing during spring.
Using a ziplock bag with a basket drawn on it, or a simple cup, students manipulate a set number of jelly beans (eggs) to discover all of the addition combinations of that number. Some eggs go inside the basket, and the rest go outside of the basket. Students then record their number sentence on the printable.
Enjoy! ~ bren in room 10
