Introduction

We've just finished the chapter on Number Sense. Let's do a review to ensure we have mastered each topic.

Number Sense

In this chapter we covered the following topics:

  •  Exponent notation 
  •  Evaluate exponents 
  •  Factors and greatest common factor (GCF) 
  •  Multiples and least common multiple (LCM) 
  •  Problem solving with GCF and LCM 
  •  Identify and represent integers 
  •  Integers in the real world 
  •  Compare and order integers 
  •  Identify and represent rational numbers 
  •  Compare and order rational numbers 
  •  Opposites of integers and rational numbers 
  •  Absolute values and number lines 

Outcomes

6.NS.B.4

Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor.

6.NS.C.5

Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g. Temperature above/below zero, elevation above/below sea level, debits/credits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

6.NS.C.6

Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.

6.NS.C.7

Understand ordering and absolute value of rational numbers.

6.EE.A.1

Write and evaluate numerical expressions involving whole-number exponents.
