The first thing you need to do is buy a box of pudding and make it (following the instructions on the box). After the pudding is made (and chilled) put it into a gallon ziplock bag, making sure to push as much air out at possible. Next get these letter pages for handwriting practice and laminate them so that you can use them again (and just in case you get pudding on them hehe). When you're ready for school, put the bag of pudding over the letter pages and let your little one practice writing their letters. Or Teacher/Mama/Daddy could call out a letter and the student could form the letter in the pudding. Another thing I did was put the bag of pudding over an alphabet puzzle so Dutch could practice writing the alphabet.
See, isn't that a fun way to practice letters???? Much better than worksheets, right???? Try this at home with your preschooler and let me know what they think :-)
