My daughter is 4 and has started in JK at school but I took her out to homeschool because she wasnt learning anything in school. I started with apps, and this is my daughters favourite! She has learned so much already and is climbing farther into levels! She plays this for hours every day and loves it! I recommend this to kids in preschool as a fun, interactive learning at home!
