Use this practice well
Find a common denominator before adding fractions with unlike denominators. Write an equivalent form for each addend so the steps remain visible and easy to check.
What this develops
Make fraction addition problems and simplify the final sums.
A mistake to watch for
Adding the denominators together changes the size of the pieces and does not find the sum.
Ways to use it
- Focus on common denominators.
- Assign independent calculation practice.
- Compare unsimplified and simplified answers.
