Teaching tips & learning objectives

Learning objectives

  • Write a conversion ratio (fraction) so that units cancel correctly when converting a measurement

  • Convert customary units of length and time (inches, feet, yards, miles, hours, minutes, seconds) using ratio reasoning

  • Convert metric units of length (millimeters, centimeters, meters, kilometers) using ratio reasoning

  • Solve multi-step word problems that require more than one conversion ratio

Teaching tips

  • Walk through both worked examples on the guided-notes page as a class before releasing students to the guided-practice problems

  • Point out that every practice problem stays within one measurement system; use this as a springboard to a follow-up lesson on cross-system (customary-to-metric) conversion if that skill is also a goal

  • Have students underline the conversion fact (e.g., '1 yard = 3 feet') before setting up their ratio, especially for the multi-step word problems on page 3

  • Use the step-by-step answer key to model a full solution on the board for any problem type students find difficult

Skills covered

  • Ratio-based unit conversion — students write and apply a conversion ratio to convert a measurement to a new unit.

  • Multi-step problem solving — students chain two or more conversion ratios together to solve word problems.

  • Table reference use — students read quick-reference conversion tables to find the conversion factor they need.

Good to know

Questions teachers ask about this resource

Does this resource include customary-to-metric conversions, like miles to kilometers?

No. Every guided and independent practice problem converts within a single system — either customary-to-customary (inches, feet, yards, miles) or metric-to-metric (centimeters, meters, kilometers) — no problem crosses between the two systems.

What units besides length appear in the practice problems?

Time conversions — hours, minutes, and seconds — appear throughout guided and independent practice, even though the reference tables only cover length, capacity, and weight/mass; no capacity or weight/mass conversions actually appear in any practice problem.

Curriculum

Standards, concepts & topics

Standards

  • 6.RP.A.3 — Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. a. Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios. b. Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed? c. Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent. d. Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
