Fourth graders sort out when to reach for inches versus miles, ounces versus tons, and cups versus gallons, and match each customary unit to what it measures and roughly how large it is.
Students will be able to…
A pencil is measured in inches, a road trip in miles. Both are length, so how do you choose the right customary unit for what you are measuring?
Project this and match each customary unit to what it measures — tap a unit, then tap what it measures and about how big it is.
Tap any phase to open the teacher moves and student actions.
You would measure a pencil in inches, but a road trip in miles. Both measure length, so how do you know which customary unit fits what you are measuring?
Students match each unit to what it measures.
Students choose a sensible unit.
Students build a unit reference.
Students reflect on customary units.
Aligned to the Common Core State Standards for Mathematics (High School Algebra II).
Know relative sizes of measurement units within one system of units including customary units.
Use the four operations to solve word problems involving distances, intervals, masses, and volumes.
Measure and estimate liquid volumes and masses of objects using standard units.
Use appropriate tools strategically.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students list length, weight, and capacity, add two units under each, and give a real example, so the units turn into a reference they can use. A printable customary-units worksheet is in the Mathematics library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
A quick self-check with instant feedback, drawn from this lesson’s key terms.
A print-and-go review sheet with a built-in answer key. Tap “Show answer key” to reveal answers, or print the clean version for students.
