Measurement…I thought we were done with that Get yourself a tissue and pay attention. First off, we learned how to convert

measurement. Second, some of the questions on the

PSSA will ask you to add or subtract measurement.

What we will do today is to add and subtraction measurement.

Psss…you’re going to need your Formula Sheet (aka BFF) to get the conversions

Adding Measurement Example: 4 ft 7 in + 9 ft 6 in First, we want to write vertically

4 ft 7 in

+ 9 ft 6 in

13 ft 13 in Can we have 13 inches? So we need to change 13 inches. 13 inches = 1 ft 1 in 13 ft

+ 1 ft 1 in

14 ft 1 in

You try

12 lb 8 oz + 9 lb 11 oz 12 lb 8 oz + 9 lb 11 oz 21 lb 19 oz 19 oz = 1 lb 3 oz 21 lb + 1 lb 3 oz 22 lb 3 oz

Subtracting Measurement

Example: 9 ft 4 in – 3 ft 9 in First, we want to write vertically

9 ft 4 in - 3 ft 9 in What can we do? 5 ft 7 in

8

16 We move one foot which is 12 inches over with the 4 inches

You try

Example: 27 lb 7 oz – 19 lb 12 oz

27 lb 7 oz - 19 lb 12 oz 7 lb 11 oz

26

23 We move one pound which is 16 ounces over with the 7 ounces
