I've bought over 20 Pre-K books (my son loves them) and this is definitely a good buy. PROS: 1. 34 pages - plenty of room to practice.2. It gradually becomes more complicated - first we draw 1-5, then 1-8, then 1-10.3. The price is quite cheap so you won't lose too much even if your kid doesn't like it. The only negative I can see is that it only has tracking exercises so it can get boring pretty quickly. I gave my son a few pages every day so he was very happy about it. Definitely a great way…
