5.NNR Number and Number Relations

5.1 Differentiate between the terms factor and multiple, and prime and composite
5.2 Recognize, explain, and compute equivalent fractions for common fractions
5.3 Add and subtract fractions with common denominators and use mental math to determine whether the answer is reasonable
5.4 Compare positive fractions using number sense, symbols (i.e., <, =, >), and number lines
5.5 Read, explain, and write a numerical representation for positive improper fractions, mixed numbers, and decimals from a pictorial representation and vice versa
5.6 Select and discuss the correct operation for a given problem involving positive fractions using appropriate language such as sum, difference, numerator, and denominator
- Add and subtract fractions: Add and subtract fractions with like denominators: word problems (Fifth grade - M.2)
- Add and subtract fractions: Add 3 or more fractions: word problems (Fifth grade - M.8)
5.7 Select, sequence, and use appropriate operations to solve multi-step word problems with whole numbers
5.8 Use the whole number system (e.g., computational fluency, place value, etc.) to solve problems in real-life and other content areas
5.9 Use mental math and estimation strategies to predict the results of computations (i.e., whole numbers, addition and subtraction of fractions) and to test the reasonableness of solutions
5.10 Determine when an estimate is sufficient and when an exact answer is needed in reallife problems using whole numbers
- Addition and subtraction: Estimate sums and differences: word problems (Fifth grade - D.11)
- Multiplication: Estimate products: word problems (Fifth grade - F.9)
5.11 Explain concepts of ratios and equivalent ratios using models and pictures in real-life problems (e.g., understand that 2/3 means 2 divided by 3)

5.ALG Algebra

5.12 Find unknown quantities in number sentences by using mental math, backward reasoning, inverse operations (i.e., unwrapping), and manipulatives (e.g., tiles, balance scales)
5.13 Write a number sentence from a given physical model of an equation (e.g., balance scale)
- Algebra: Write equations to represent word problems (Fifth grade - P.4)
- Algebra: Write linear functions (Fifth grade - P.9)
5.14 Find solutions to one-step inequalities and identify positive solutions on a number line

5.MEA Measurement

5.15 Model, measure, and use the names of all common units in the U.S. and metric systems
5.16 Apply the concepts of elapsed time in real-life situations and calculate equivalent times across time zones in real-life problems
5.17 Distinguish among the processes of counting, calculating, and measuring and determine which is the most appropriate strategy for a given situation
5.18 Estimate time, temperature, weight/mass, and length in familiar situations and explain the reasonableness of answers
- Measurement: Reasonable temperature - Celsius and Fahrenheit (Fifth grade - V.10)
- Time: Find start and end times: word problems (Fifth grade - W.5)
5.19 Compare the relative sizes of common units for time, temperature, weight, mass, and length in real-life situations
5.20 Identify appropriate tools and units with which to measure time, mass, weight, temperature, and length
5.21 Measure angles to the nearest degree
5.22 Compare and estimate measurements between the U.S. and metric systems in terms of common reference points (e.g., l vs. qt., m vs. yd.)
- Measurement: Convert between metric and customary units (Fifth grade - V.9)
5.23 Convert between units of measurement for length, weight, and time, in U.S. and metric, within the same system

5.GEO Geometry

5.24 Use mathematical terms to classify and describe the properties of 2-dimensional shapes, including circles, triangles, and polygons
