My kindergartner LOVED homework in preschool (I was opposed to it and complained to the school but once she saw it she was obsessed and I couldn't stop her). There is no homework in her kindergarten, but she has started asking for me to make up homework for her. She has the Highlights kindergarten workbook, but is almost done with it. She's particularly asking for more math problems. Are there any workbooks you've used that you would recommend?
