Instead of relying on calculators, students learn strategies that can improve their concentration and estimation skills while building number sense.
And, while there are educators who oppose math “tricks” for valid reasons, proponents point to benefits such as increased confidence to handle difficult problems.
Once you’ve identified your clue words, highlight or underline them.
This will let you know what kind of problem you’re dealing with.
If you begin to solve problems by looking for clue words, you will find that those words often indicate an operation.
This, of course, means looking for clue words as outlined in the previous section.
Let’s say students must find the sum of 393 and 89.
They should quickly see that adding 7 onto 393 will equal 400 — an easier number to work with.
Most will feel that 500 is a simpler number than 567.
So, they just have to take away 67 from the minuend — 567 — and the subtrahend — 153 — before solving the equation.
