Preschool Number Sense Routine Perfect for Transitions

Moving from one activity to another just got a lot more mathematical with this simple routine that builds early number sense with preschoolers. This dot card transition requires only index cards with 1 to 4 dots in various arrangements. Putting them on a ring makes this a handy and quick routine for those in-between times.

In this video you can see how the teacher asks children to show the same amount of fingers as dots on a given card. Much more powerful than traditional numeral flashcards, dot cards focus children on the cardinal amount of a set of dots, while connecting the number word to its quantity. Having to produce a similar-sized set of fingers requires children to translate from one representation (dots) to another representation (fingers) of the same quantity.

Notice that the dot cards are flashed for just a short time. This routine builds children’s ability to subitize — that is, to see small quantities and instantly know how many in the set without counting. Therefore, while this routine can deepen over time, the dot cards remain small quantities up through 4 (or maybe 5) that children can perceive without needing to count.
