My preschooler really wants to be like her big siblings and do school. Some days when she asks, I have time to sit and do an activity with her. But sometimes she asks during a math lesson with one of the big kids. She does like the occasional worksheet as it reminders her of her siblings' school work, so I'm looking for worksheets that she can do while sitting next to me, but without my guiding her step by step. I can take the time to explain the worksheet ("start the maze here, exit here" or "circle all the letter a's").
She can recognize her digits 0-9 and is learning her letters. Fine motor skills are OK for her age, but not advanced enough for things like independent handwriting worksheets or anything. I'd prefer black and white, because we don't have a color printer. I'm willing to pay a small amount for very well done worksheets, but I'm not really looking for a full "curriculum" of worksheets as I only do school when she asks at this age.
