How it works
To find how much longer one thing is than another, take the shorter from the longer.
Missing the whole? Add the parts. Missing a part? Take away.
Draw a bar for each length. The gap between the ends is how much longer.
Worked examples
Two things on a ruler
- The pencil ends at 5 and the crayon ends at 12 on the same ruler.
- How much longer is the crayon? Take away: 12 − 5 = 7.
- The crayon is 7 in longer.
Joining two pieces
- Sam's ribbon is 97 centimeters long. Sam cuts off 21 centimeters. How long is the ribbon now?
- Joining makes a whole, so add the two lengths.
- So the answer is 76.
One is longer by an amount
- Lee's stick is 71 centimeters long. Lee's rope is 23 centimeters longer than the stick. How long is the rope?
- The longer one is the shorter plus the difference, so add.
- So the answer is 94.
