Which One Doesn’t Belong? Secret Decoder Super Fun Deck has 100 double-sided cards (200 activities) to challenge children as they choose which item in a list of six items does not belong. On Level One cards (red border), the one that doesn't belong is very different from the other items (ex. blue, green, star, red, purple, yellow). On Level Two cards (blue border), the answer choice is more difficult to determine (eg. polka dot, green, floral, plaid, striped, checkered). Players check their answers with the Secret Decoder or the Answer Key.
To assist in the learning process, the topics on each card side relate to each other. The example above has colours on the Level One side and patterns on the Level Two side. Which One Doesn’t Belong? also includes game ideas.
