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
