Unit 2: Exploring Comparisons, Area & Perimeter, and Factors & Multiples

• Multiplicative Comparisons: Comparing two or more things using multiplication (Bill is three times taller than Tim)

• Additive Comparisons: Comparing two or more things using addition (Jenna has 4 bananas and Kate has 12 bananas. How many more bananas does Kate have?)

• Factor: Numbers we can multiply together to get another number

• Multiple: A multiple is the result of multiplying a number by another number

• Product: The answer when two or more values are multiplied together.

• Array: Items (such as objects, numbers, etc.) arranged in rows and/or columns.

• Prime: A whole number greater than 1 that can not be made by multiplying other whole numbers

• Composite: A whole number that can be made by multiplying other whole numbers.

• Area: The size of a surface.

• Square Unit: The area equal to a square that is 1 unit on each side

• Equation: An equation says that two things are equal.

• Unknown: When we do not know a value, we can use a variable or an unknown to represent it. 3xn=6 n is our unknown. We can solve to find n=2
