Snowball fight in the classroom! Students can work in groups or with a partner on this game by rolling and adding. This is a great game for winter math stations.
Log in to see state-specific standards (only available in the US).
Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
Apply properties of operations as strategies to add and subtract. If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
