If your child has a problem with spelling then you need to help them, but we all know that reciting words, and writing them is not much fun.
Children learn more when they are having fun, and can associate fun with learning.
The following games can be played almost anywhere, at anytime. Using a list of spelling words, the leader says I am thinking of a word that has X number of letters. The children have to guess at the first letter, when the first letter is correctly identified the leader continues with I am thinking of a word that starts with X letter and has X more letters. You can vary this by naming the number of vowels instead of the letter total. The first child to get the word right gets to be the leader in the next round.
