Preschoolers were shown a split screen that flashed blue dots on one side and yellow dots on the other. They were asked to identify the side with more dots.
. . . kids who participated in the dots activity performed better in a follow-up test of more discrete math skills assessed with questions like: ”Count backward starting from 10.” Or ”Joey has 1 block and gets 2 more; how many does he have altogether?”
Researchers also assessed the children’s ability to say which of two numbers is bigger and to read and write numerals.
“Among the children who practiced with the dots, those who practiced with easier dot problems first and then progressed to harder ones did even better than kids who did the problems in a random order,” writes Lilian Mongeau in Education Week.
