What You Need:
- Paper
- Pen
- Math fact "decoder" key
- Message
What You Do:
- Make up some addition problems for your child to solve. Make a decoding sheet to correspond with the answers, and write a letter for each answer to create a message!
- Write your message on the decoder key, by making a small line for each letter of the alphabet in the message.
- Write out your message lines, and then let your child take a whack at the math facts to decode your words. The sum of each pair of numbers appears under each line of the message, and matches up with a letter. For a child who is making good progress on math facts, this is a fairly fast activity … but one that will bring a sense of accomplishment that lasts all day and beyond!
