Invitation to Learn
Math/Science—Create a hidden message that your class can decode and have them work with their partners on decoding it. This could be one of your science questions or some math vocabulary.
Extend this activity by changing the number strips so that A= 7. This will realign all the assigned values. You can also change the number strip by writing different values such as decimals or fractional numbers.
Homework & Family Connections
Have students create a message that a family member can decode and vice-versa.
Have students use their decoding machine to find the value of their spelling words. Encourage partners to create a message for each other to decode.
