  1. Parent math night Fourth grade 2017-2018

  2. Unit 3 vocabulary terms • Associative Property – Multiply the parenthesis first, then the other factor, and you will still get the same product (2 x 5) x 3 = 2 x (5 x 3) • Commutative Property – Multiply the factors in any order and you will get the same product • Factors – the numbers you multiply in a multiplication equation • Area Model – a multiplication or division model that represents the place value of each digit in a number • Distributive Property – Multiply the digit outside of the parenthesis by each digit inside the parenthesis ex. 2 * (4 x 8) = (2 *4) x (2 * 8) • Product – the answer to a multiplication equation

  3. Place value sections model 100 35 135

  4. Expanded notation method 2 42 40 4 4 40 4 160 8 4 2 168

  5. Distributive property 210 12 222

  6. Algebraic notation method 60 2 2 8 60 8

  7. Partial products & shortcut method

  8. practice • Show a new way to multiply: 7 * 321 28 x 74 3 (8,153)

  9. Unit 4 vocabulary terms • Remainder – the left over amount after dividing

  10. Divide with zeros & remainders • Think about how much easier this problem is to solve by knowing 3x7=21. • Multiplication mastery is important to division problem-solving. • Help your child achieve mastery by practicing every night.

  11. Place value sections method

  12. Expanded notation method

  13. Digit-by-digit method

  14. Diving with zeros 1 9 5 R 3 900 0 R 3 1,000 5 5 Frequent student mistake! Diving with zeros can be tricky for students. The place value sections method will show why the tens place will have a zero. Using the digit-by-digit method can be confusing until this comprehension of numbers is mastered.
