About this game
Powers and exponents: a free Grade 6 math game for ages 11-12. Kids find the value of a number raised to a power. Each round brings 10 fresh questions with new numbers; instructions are read aloud and every answer is checked.
Three to the power of 4 looks smaller than 3 × 4. It is almost seven times bigger. Powers and exponents shows one power per card, with a base from 2 to 10 and an exponent of 2, 3 or 4, with the small raised number spelled out in words beside it. Ten cards make a round in this Grade 6 game; the list is short, so a card can come back in the same round. Your child types the value; each answer is checked.
An exponent counts factors. The hint puts it plainly: the exponent says how many times the base is used as a factor, so 3 to the power of 4 is 3 × 3 × 3 × 3, which is 81. Answers climb fast, from 4 for 2 squared up to 10,000 for 10 to the fourth. That growth is half the lesson.
The raised 4 tempts a times sign. For 3 to the power of 4, a quick answer of 12 multiplies base by exponent. Ask, "How many 3s are being multiplied together?" Writing them out in a row fixes it. Then say, "You wrote out all four factors."
