Last year my sister-in-law told the family about a little program she had enrolled her daughter in, it's a free, at-home "preschool" developed by the Waterford Institute. It's to help kids get a jump on learning before entering kindergarten. Upon her recommendation, three more of the Westra grandkids (Colton being one) were accepted into the program (there are a limited number of spaces, so you do want to register early). After an orientation, we were sent home with an external hard drive and then Colton was to work with Rusty and Rosie Raccoon for 15 minutes, at least five days a week.
Some days he was really good at doing his computer preschool. Other days I had to push (and bribe) him. We just finished up and are returning our equipment. Between his regular preschool, Rusty and Rosie, and just being a smart little fellow, I think Colton is more than ready for kindergarten!
If you have a preschool age child and wanted to look into Rusty and Rosie for yourself ... here's the link to Utah Upstart.
