3.MD.B.4 lessons
Generate measurement data by measuring lengths and show the data on a line plot marked in whole numbers, halves or quarters. (The standard names rulers marked in halves and fourths of an inch; US classes can measure feet in inches in Lesson 1.)
The Common Core State Standards for Mathematics code 3.MD.B.4 asks students to: “Generate measurement data by measuring lengths and show the data on a line plot marked in whole numbers, halves or quarters. (The standard names rulers marked in halves and fourths of an inch; US classes can measure feet in inches in Lesson 1.)” These Fieldbook lessons teach it hands-on, with everyday materials, a printable teacher guide and a student sheet.
Measure It: Length, Time and Mass in the Real World Grade 3
- Whose foot is the right ruler? 50–60 min
Teams measure the same taped line on the floor in heel-to-toe steps and get different answers, then measure it again with metre sticks and all agree. Students explain why the world needs standard units, and measure their own feet to build a class line plot.
- Can we design the best paper airplane? 55–60 min
Teams fold a classic dart and their own design, fly each one five times from the same line, and measure every flight with a tape measure. Students find the middle value for each design, plot the class results, and use the data to argue which design really flies farther.
