How do you prepare kids ages 4+ for preschool? With Hot Dots! This prep set of flash cards for toddlers was developed by teachers to help kids learn essential reading and math skills for preschool. What makes this set better than regular 123 and ABC flash cards? Hot Dots are interactive so kids can learn at their own pace, self-correct, and build confidence with the interactive pen. How does the pen work? When you press it to an answer dot, the pen lights up; green for correct answers, red for incorrect. The pen can also play sounds or be muted; the pen does not talk. Make learning interactive with Hot Dots! At Educational Insights we've been helping kids learn through play for 60 years. We work with experts in distinct fields to ensure that our products are the very best they can be.
