Preparatory Writing Exercises - With stickers. In this exercise book, your preschooler can practice writing the letters of the alphabet to their heart's content: first, your child can follow the dotted lines, then they can try to write the letters themselves. And everything is only complete when your preschooler has also placed the stickers in the correct spots. There are almost a hundred of them! There is also an exercise book with writing exercises for children in their first year of primary school.
