Grade 5 - Number
Standard 5.N.6 - Solve addition and subtraction word problems with decimals.
Included Skills: Decimals, Mixed Equations
Demonstrate understanding of decimals to thousandths by: • describing and representing • relating to fractions • comparing and ordering. • Tell a story (orally, in writing, or through movement) that explains what a concrete or pictorial representation of a part of a set, part of a region, or part of a unit of measure illustrates and record the quantity as a decimal. • Represent concretely or pictorially a decimal identified in a situation relevant to self, family, or community. • Recognize and generate equivalent forms (decimal or fraction) of fractions and decimals found in situations relevant to one's life, family, or community. • Demonstrate, using concrete or pictorial models to explain, how a quantity in tenths or hundredths can also be recorded as hundredths or thousandths (e.g., 0.2 can be written as 0.200). • Describe the quantity represented by each digit in a given decimal. • Make and test conjectures about the relationship of equality of quantities written in decimal and fractional form (e.g., 0.7 and 7/10) and verify concretely, pictorially, or logically. • Use and explain personal strategies for writing decimals as fractions. • Use and explain personal strategies for writing fractions with a denominator of 10, 100, or 1000 as a decimal. • Explain, by providing examples, how to write decimals as a fraction with a denominator of 10, 100, or 1000. • Identify benchmarks on a number line that could be used to order a given set of decimals and explain the choices made. • Use benchmarks to order a set of decimals from a situation related to one's life, family, or community.
