Are the rest of the pages also this easy?** A: I believe this product is typical of other educational tools for pre K. Starts out simple and progressively gets difficult. My grandson enjoyed it pre K, now in Kindergarten does not play with it. I now purchase grade 1 - 2 educational tools. I’m guessing you’re 2 yr old will enjoy this, toy itself corrects and congratulates, sometimes more fun than than parent. **Q: are the Hot Dots books reusable?** A: Yes. They are. **Q: is this book used to count to 10 or 100?** A: Hi, this set is mainly focused on Preschool skills, it does have a challenge to count to 100 at the end of book 2 but is not focused on that. Hope that helps. **Q: Can they actually trace the number with the pen?** A: Yes they can with the math program. I bought 3 diffrent programs and xtra pens ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for reinforcements *by T***M on December 1, 2025* My students love these. They are easy to use and fun for the kids!
