This activity came from 1 + 1 + 1 = 1 . Right now I am focusing on cards 1-5 with Abby. However, we practice using all of them and, of course, she enjoys putting pom-poms on every single circle. I haven’t attached velcro to the pom-poms or cards as suggested, but I plan on getting that done soon. Without it, they roll around too much and it can be difficult for tiny fingers to make them stay put.
You can print off your own set of number cards at the site listed above. Then, you simply cut them out, laminate and attach velcro. This uses the really tiny pom-poms, which you can typically find at dollar stores.
