Standards for mathematical practice
MA.6.AR.3 Understand ratio and unit rate concepts and use them to solve problems.
MA.6.AR.3.1 Given a real-world context, write and interpret ratios to show the relative sizes of two quantities using appropriate notation: 𝑎/𝑏 , 𝑎 to 𝑏, or 𝑎: 𝑏 where 𝑏 ≠ 0.
MA.6.AR.3.2 Given a real-world context, determine a rate for a ratio of quantities with different units. Calculate and interpret the corresponding unit rate.
MA.6.AR.3.3 Extend previous understanding of fractions and numerical patterns to generate or complete a two- or three-column table to display equivalent part-to-part ratios and part-to-part-to-whole ratios.
MA.6.AR.3.4 Apply ratio relationships to solve mathematical and real-world problems involving percentages using the relationship between two quantities.

-
Find the unit rate given a real-world scenario.
-
Identify and create equivalent ratios using a table.
-
Find a missing part or a whole and a missing percent given a scenario.
