Locating Numbers on a Number Line 18 When locating numbers on number lines it is important to note the scale of the line. Lesson 1 has a scale of numbers to 100 within a decade Lesson 2 has a scale from 0-100 Lesson 3 has a scale from 0-1000 Lesson 4 has a mixture of scales 90 320 (c) Professor Pete's Classroom, 2017. All rights reserved.

Locating Numbers on a Number Line Students can draw their own blank number lines Or a sheet can be printed off with the blank number lines Students will need to write the two numbers on the lines. This helps them establish the scale. Teacher discretion is needed for some exercises as complete accuracy is not expected. A close approximation is all that can be achieved. 92 100 (c) Professor Pete's Classroom, 2017. All rights reserved.
