  6. 16. whole numbers that multiply together to get the given number.
  7. 18. the amount left over when one number does not divide another number a whole number of times.
  8. 19. a group of one or more numbers, unknowns, and/or operation symbols that represent a quantity.

  1. 1. a number that is multiplied.
  2. 2. a comparison that tells how many times as many. For example, 7 x 3 = 21 tells that 21 is 3 times as many as 7, and that 21 is 7 times as many as 3.
  3. 3. an operation used to find the total number of items in a given number of equal-size groups.
  4. 4. to make something clear and easier to understand.
  5. 5. (verb) to give an approximate number or answer based on mathematical thinking.
  6. 6. a number that has more than one pair of factors.

  8. 12. to say or show that something is true or correct.
  9. 13. a whole number greater than 1 whose only factors are 1 and itself.
  10. 15. a mathematical statement that uses an equal sign (=) to show that two expressions have the same value.
  11. 17. to take turns.
  12. 20. a set of objects arranged in equal rows and equal columns.
