New York State Common Core Math Grade 5, Module 6, Lesson 1

Lesson 1 Concept Development

Problem 1: Create a number line by choosing a unit length, an origin, and a direction of increase.
Problem 2: On the number line created above, partition unit lengths into fractional units, and label those fractions.
Problem 3: Identify the coordinate of a given shape placed on a number line.

Lesson 1 Problem Set

1. Each shape was placed at a point on the number line S. Give the coordinate of each point below.
2. Plot the points on the number lines.
3. Number line G is labeled from 0 to 6. Use number line G below, to answer the questions.
   a. Plot point at 3/4.
   b. Label a point that lies at 4 1/2 as B.
   c. Label a point, C, whose distance from zero is 5 more than that of A.
   The coordinate of C is ______.
   d. Plot a point, D, whose distance from zero is 1 1/4 less than that of B.
   The coordinate of D is ______.
   e. The distance of E from zero is 1 3/4 more than that of D. Plot point E.
   f. What is the coordinate of the point that lies halfway between A and D?
   Label this point F.
4. Mrs. Fan asked her fifth-grade class to create a number line. Lenox created the number line below: Parks said Lenox’s number line is wrong because numbers should always increase from left to right. Who is correct? Explain your thinking.
