We put each page into plastic page protectors so we can use dry erase markers. I create notebooks for each of the kids with about 20 pages of plastic-protected activities. I switch them out every so often so they have something new and challenging.
This notebook idea works best with younger children since their workbook pages focus on tracing, writing coordination, drawing, and writing their first letters and numbers. It may not be as helpful for older children whose workbook pages would require detailed work, such as writing or math, since its difficult to write details with a dry erase marker.
Our favorite workbooks are the Kumon Workbooks. They are simple, cute, and fun! I also usually include pages with their name or the alphabet written in big letters, so they can practice tracing their name. Once you have your preschooler’s workbook put together you can keep it on a low shelf so they can reach it themselves and work anytime they feel so inclined.
