What you can do to make working on printable worksheets more enjoyable for your child may often depend on the age and interests of the child. For example, older children may have to read a poem which is on the sheet and then write their own poem in the same sort of style.
A young child may not be able to write or read more than a few words. Worksheets should be created keeping these factors in mind. When you buy worksheets for your children, look for how the concept is explained. Is it pictorial or is it just a collection of words? A pictorial worksheet will hold the attention of a child more than just a combination of words.
