Kids transform into magicians, being able to predict what number is on a die's bottom face, just by looking at the dots on top. All you need is one six-sided die. Roll it and say the number. Then, subtract the number from 7. For example, if you roll a 1, subtract 1 from 7. You get the number 6. Flip the die over, it's 6! This trick always works. No matter what the die lands on, always subtract it from the number 7. Impress your friends and work on your subtraction skills!
