Counting and cardinality are key to building basic number sense in young mathematicians. Beginning with writing numbers to 10, the collection is organized so that each resource directly relates to, or builds upon, the previous one. Learners are able to count and write numbers all the way to 120 before learning how to skip count by 2s, 3s, 5s, and 10s. These skills all help build basic number sense in order to add and subtract. The collection includes helpful math tools, such as ten frames, hundred charts, and dot cards, that prove valuable in reinforcing these skills.

Looking for all things third grade Common Core math? Here is the collection you've been waiting for! Third grade math curriculum is rigorous and opens up the doors to bigger algebra concepts that learners will use their entire lives. From multiplying and dividing to identifying polygons to telling time to naming parts of a whole, this collection can serve as a baseline for third grade math instruction. Each resource in the collection is designed to meet one or more of all 37 Common Core State Standards in third grade mathematics.
