I love the ability to "do school" anywhere. We had about a 45 minute drive home from a playdate the other day. Just a few minutes into the drive, Nugget started figuring out and talking about various addition facts (up to 5). So I picked the thread up and we chatted about those for a while. Then we moved on to the 5+x facts that RightStart Math emphasizes. We made a little game out of both. Then we reviewed odds and evens, then Nugget decided to count to 100. THREE TIMES. By the time she'd finished that, we were almost home -- and math was done for the day!
