Unit: 4.7

Students extend their understanding of adding and subtracting whole numbers in order to perform the same operations with fractions that have the same denominator. They work with decomposing fractions into a sum of fractions, add and subtract mixed numbers, and solve word problems using these skills. Students work with decimals, using fraction equivalence in the special case of $\frac{a}{10} = \frac{a \times 10}{100}$ to understand, e.g., that $0.67 = \frac{6}{10}+\frac{7}{100}$.
