Standard 7.N.5 - Practice rounding mixed numbers to the nearest whole number.
Included Skills: Fractions
Develop and demonstrate an understanding of adding and subtracting positive fractions and mixed numbers, with like and unlike denominators, concretely, pictorially, and symbolically (limited to positive sums and differences). • Estimate the sum or difference of positive fractions and/or mixed numbers and explain the reasoning. • Model addition and subtraction of positive fractions and/or mixed numbers using concrete or visual representations, and record the process used symbolically. • Determine the sum or difference of two positive fractions or mixed numbers with like denominators and explain the strategy used. • Explain how common denominators for fractions and/or mixed numbers and factors are related. • Explain how a common denominator can help when adding fractions and/or mixed numbers. • Determine the sum or difference of two positive fractions or mixed numbers with unlike denominators and explain the strategy used. • Simplify a positive fraction or mixed number by identifying and dividing off the common factor between the numerator and denominator. • Generalize and explain personal strategies for determining the sum or difference of positive fractions and/or mixed numbers. • Solve a problem involving the addition or subtraction of positive fractions or mixed numbers. • Explain how the sum or difference of positive fractions and/or mixed numbers can be represented symbolically in different ways.
