ROUNDING AND ADDING FRACTIONS
To estimate with fractions, a good place to start is rounding each fraction to the nearest one-half, and then estimate. Think of the number line and where each fraction belongs on it. Estimating fractions before performing the actual operations help to know if the answer is reasonable.
To find sums with fractions, we’ll explore the meaning of adding fractions and then practice additional problems. First we’ll look at adding fractions with like denominators using fraction bars and justify the sums with fraction bars. After using the fraction bars to add, we’ll practice adding fractions with like denominators using paper and pencil.
We can also use fraction bars to add fractions with unlike denominators and justify the sums. After using fraction bars to add fractions with unlink denominators, we’ll practice adding fractions with unlike denominators using paper and pencil.
