This CD has been my saving grace. My daughter is 2.. almost 3. Been having a hard time potty training and I know most pre-schools need them potty trained before they can enroll. My daughter is very bright and knows her colors and ABCs and can count to 50 already. She learns a lot from the iPad and reading with me. I wanted something for her that I could do at home as either as supplement to pre school or home school for pre school if needed. This CD had 10 months worth of lesson plans and around 900 pages of printable material. I think this curriculum can be purchased as a book as well, but I chose the CD. The printables go along with the lesson plans and I could not be happier. reinforcing her knowledge on paper is what I wanted and is exactly what I got with this CD. All my friends tell me to do ABCmouse.com, but I want my little one to learn how to write and actually do the work on paper and not learn how to write her name with a mouse and screen. I am beyond happy and love that my daughter can learn at home…even if she is too stubborn to pee in the potty!
