Word problems III

Lesson

When we have a written problem, we can look for words that give us clues. Some words that could be clues for addition include:

- more
- longer
- later
- bought
- joined

For subtraction, words might be:

- less
- shorter
- earlier
- sold
- left

In this video, we search for clues in the words, and solve problems with more than one part.

Remember!

As long as we follow the order of operations, we can solve some parts of our problem first.
