A measurement activity that makes you smile!
How long is your smile? This is a terrific lesson to reinforce using tools to measure, gather accurate data and analyze the results. Students also work on being a participating member of a collaborative group. All in all, this is a fun community-builder that practices measurement skills.

After all the measuring and data collection, you will end up with a line plot where students can figure out the typical length of smile for a student of a particular grade.
I have included a small standards poster to display next to your giant smiley in the hallway or lunchroom so staff and other students can see how you have been applying math standards with your class. You could post the line plot you create alongside!
Scoring rubric included (of course!).
Common Core Standards
Grade 3: Math
- 3.MD.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot.
Grade 4: Math
- 4.MD.1 Know relative sizes of measurement units within one system of units. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table
- 4.MD.4 Make a line plot to display a data set of measurements in fractions of a unit.
Grade 5: Math
- 5.MD.1 Convert among different-sized standard measurement units within a given measurement system, and use these conversions in solving multi-step, real world problems.
- 5.MD.2 Make a line plot to display a data set of measurements in fractions of a unit. Use operations on fractions for this grade to solve problems involving information presented in line plots.
