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