Fourth grade

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

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.
