Study Guide – Multiplication Test
Test Date: Friday 11/13
 Students must be able to explain and apply the properties of multiplication
(Identity property, zero property, associative property, commutative
property, and distributive property).
 Students must be able to understand and distinguish between the concepts
of area and perimeter.
 Students must be able to list factors and/or multiples for a given number;
students must be able to distinguish between a factor and a multiple.
o List the factors of 20 - { 1,2,4,5,10,20}
o List the multiples of 20 - 20, 40, 60, 80…
 Students must be able to find the greatest common factor (GCF) and the
least common multiple (LCM) of two given numbers.
 Students must be able to identify a number as prime or composite.
Ex: 81 is composite
53 is prime
 Students must be able to draw arrays for a given perimeter.
Perimeter: 14 units
Possibly arrays: 6 x 1 or 1 x 6
5 x 2 or 2 x 5
3 x 4 or 4 x 3
 Students must be able to determine the area, perimeter, and factor pair of a
given array; Students must be able to draw and label the array for a given
factor pair.
6
3
Factor Pair: 3 x 6
Area: 18 units²
Area =(length x width)
Perimeter: 3+ 3+ 6+ 6= 18 units
Perimeter=L+L+W+W
 Students must be able to name a number based on information (clues)
provided.
 Students must be able to create 5 digit numbers based on divisibility
requirements.
 Students must be able to multiply numbers by multiples of 10, 100, 1000
etc.
50 x ___________ = 30,000 (600)
33 x 3000 = ____________ (99,000)
400 x ___________ = 480,000 (1200)
 Students must be able to estimate products using concepts involving multiples
of 10, 100, 1000 etc.
*Round to the highest PV
*do NOT round single digit numbers
Example: 57 x 287
round 60 x 300 = 18,000
 Students must be able to multiply numbers using the TRADITIONAL
METHOD (regrouping) of multiplication.

 Students must be able to apply the FOUR STEP PROBLEM SOLVING
METHOD to solve application word problems.
Step 1: Find out
Step 2: Choose a strategy
Step 3: Solve it
Step 4: Look back and report answer
