Nonstandard units of measure are used to compare lengths and weights of real-world objects.

Made to measure! For this lesson students will be able to use the transitive principle for indirect measurement as they compare the lengths of the objects to each other.

Today students will focus on the idea that measuring an object using different length units will result in different measurements.

This is a short, fun lesson plan with a literature connection, "Miss Nelson is Missing". It uses candy bars as non-standard units for measuring objects in the classroom.

Do students have any idea of what a foot really is? This lesson will have students measuring objects and making predictions about the length of objects.

They measure in Japan too. Students measure two objects and compare to decide how much larger one is than the other.

Were off to get the measure, the wonderful measure of side! The students will identify the longest side of an object and measure its length with a variety of non standard units.

[Free Registration/Login may be required to access all resource tools.] Converting customary units of measurement.

Students tell how long an object is by measuring it using paper clips and comparing it to other objects measured with the same non-standard unit of measurement.

We are going for GOLD! Students will use different objects to measure the length achieved in different Olympic events.

Move over Van Halen because today we are all going to "Jump." So go ahead and jump as students solve an assessment piece and story problems involving jump lengths. If you are under 30, please Google Van Halen before proceeding.

Second graders use a variety of measurement tools to measure both small and larger distances.

First Graders need to use direct and indirect comparisons to measure objects. Today they will use their new knowledge of dinosaurs to find the longest of the giant lizards.

How do we understand the difference between inches and centimeters? Why does measuring a given object in centimeters always give a bigger number than measuring the same object in inches? This instructional activity includes detailed...
