Multiplication

Vocabulary Review

factors products
Factors & Products
  • 4 x 6 = 24
  • 4 and 6 are factors – the numbers being multiplied together.
  • 24 is the product – the answer to a multiplication problem.
estimate
Estimate
  • Estimate – to make a good guess by rounding.
  • In the problem 73 x 6, round 73 to

70 and DO NOT round the single digit number of 6!

  • This would give you a new problem of

70 x 6.

  • You can then use the basic math fact of 7 x 6 = 42 to help you get the product.
  • Simply count the number of zeros in the factors and add them to the end of the basic math fact answer. The product is 420!
multiple
Multiple
  • A multiple is the product of any two whole numbers.
  • For example: 3, 6, 9, 12, and 15 are multiples of 3.
  • 3x1=3
  • 3x2=6
  • 3x3=9
  • 3x4=12
  • 3x5=15
properties of multiplication
Properties of Multiplication
  • Zero Property of Multiplication – the product (answer) of any number times 0

is 0! 4x0=0 or 9x0=0

  • Identity Property of Multiplication – the product (answer) of any number times 1 is that number! 4x1=4 or 8x1=8
  • Commutative Property of Multiplication – two numbers can be multiplied in any order and the product (answer) is the same. 4x2=8 and 2x4=8.

Properties of Multiplication
  • Associative Property of Multiplication –

(3x2)x4 = 3x(4x2)

  • You can change the grouping of the numbers you multiply! You will still get the same product (answer).
