Help your students with number sense by warming up each Math Lesson with 5-10 of these Subitizing Cards.
Subitizing means "the ability to look at a given quantity and understand how many without the use of one-to-one counting."
Students grades K-6 with stronger subitizing skills demonstrate higher scores on standardized math tests. Number sense is THE KEY component to getting all learners to understand Math.
Utilize the red/yellow for memorizing support and the 10 frame structure to group quantities faster!
