Reading Scales The key to Success.

Formula for Success Value of Each line = JUMPdivided by# ofSPACES JUMP #of SPACES = Value of Line

What’s a “Jump” Jump is the value betweentheNUMBERS on the scale. “How much do the numbers count up by?” JUMP Jump = 5

What’s “# of Spaces?” # of spaces can be found by counting spaces betweenNUMBERS. #of Spaces =5 Spaces

To The Formula JUMP = 5 #of SPACES = 5 JUMP #ofSPACES 5 1 = = 5

Value of Each Line is 1 Now you can find the value of any line. 1 2 3 4 9 13

A Little Practice JUMP = ?? 10 ____ = 1 10 #of Spaces = ?? 27 14 10 20 30

Let’s Review “JUMP”is the value between the printed numbers. “#of Spaces”is the number of spaces you count between the printed numbers.

Let’s Review Formula for success is: JUMP #of SPACES
