2.3 Ruler problems and number lines Objective: To solve ruler problems

Ruler Rules to live by: Look at Example #1 1.Find Length 50-20=3 2.Divide Length into big blocks 30/3=10 3.Give # for Big lines 4.Divide Big Blocks into little spaces 10/5=2

Example 1: Find length 50-20=3 2. Divide length into big blocks 30  3=10 3. Give # for big lines 4. Divide big blocks into little space 10  5  2

Example# 2: =45 45  3   5  3

Ex 3:  100   4=20 20  5  4    3   5  3
