My son is 2 1/2. He has been counting for over a year. We had been doing daily "homeschool lessons" for about a month, but went out of town for a long weekend. Last night, we got in from out of town he said he wanted to do some school work. So I got out some worksheets and sat down with him. We've been working on very simple things. Writng a J (the first letter of his name), recognizing shapes (He can sort them and point out the shape when I say the name, but has been having trouble saying he names on his own) and drawing circles (he has the concept down, but the execution is still rough).
Anyway, I asked him to count the points on a star and he says "1, 4... what's next?" He knows how to count. So I just told him it wasn't right and to try again. He starts whining and throwing a tantrum, which he never does. Today, he said he didn't want to do any school work, so I figured I would just give him a break. I don't know what it is about being back home, but he's acting like he doesn't know anything anymore. We spent the weekend with my fiance, and the whole time, we would do little things to practice the things he's working on, just no structured sit down lessons.
