Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units.


General Information

Subject Area: Mathematics
Grade: 2
Domain-Subdomain: Measurement and Data
Cluster: Represent and interpret data. (Supporting Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Formative Assessments

Name Description
Measuring our Pencils Line Plot

Students make a line plot from a set of measurement data that includes measurements to the nearest whole inch.

Measuring Hand Spans Line Plot

Students make a line plot from a set of measurement data that includes measurements to the nearest whole centimeter.

Measuring our Pencils

Students measure their pencils to the nearest whole inch.

Measuring Hand Spans

Lesson Plans

Name Description
Taking Flight

Students will explore airplanes in this project-based lesson/unit with multiple lessons that are all tied to a final project.

So . . . il Pick You!

This is a Project-Based Learning Project, intended for second grade. It can be adapted and changed for other grades.

X Marks the Spot!

In this lesson, students will make multiple measurements and record the measurements on a line plot.

If the Shoe Fits...

In this lesson, students will create line plots based on linear measurements that they collect while participating in the practice of scientific inquiry.

Problem-Solving Tasks

Name Description
Growing Bean Plants

This task adds some rigor to the activity, by collecting actual growth data, providing practice for students in measuring and recording length measurements. Centimeters are an appropriate unit for these measurements, as they provide a good level of precision for these measurements, while being easy enough for students to handle.

The Longest Walk

After students have drawn and measured their ten line segments, it might be more useful for the class to discuss part (b) as a whole group. It is a good idea to have the students use color to help them keep track of the connection between a line that they have drawn and the corresponding data point on the graph.

Hand Span Measures

The size of the hand makes a difference in some sports that involve throwing or catching and some activities such as playing the piano. Hand span is a measure that has been used for many years. By placing the hand on the edge of a piece of paper and marking the tips of the thumb and little finger, the student can measure a straight line. This is a better method than placing the hand directly on the ruler. Discuss rounding conventions. This could be used as a class activity, or students could gather and plot data on separate line plots from different age groups.
