One great idea is the activity sheets based on the Disney characters and story behind Disney_Pixar's full length animated film Cars. Easily downloadable from the web, these sheets can be printed in as many copies to be repeatedly enjoyed by any school_aged Lightning McQueen fanatic.
_ Choose a word of interest to the person who receives it. Suppose, for example, that Grandma has apple decorations all over her kitchen. Your puzzle word could be APPLE. Make a rectangular puzzle that is about 12 x 12 squares. Write the word APPLE inside in different directions about 4 or 5 times. Then fill the blank spaces with A, P, L, E until all the spaces are full. Cut out the puzzle. Glue it onto a piece of red construction paper cut in the shape of an apple. Then ask Grandma, "How many times can you find the word APPLE?" She will be delighted, to the core! You can think of lots more fun words like this to hide.
