Common Core Alignment
CCSS.MATH.CONTENT.1.MD.A.1 - Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Objectives & Outcomes
Students will measure objects based on a set object (such as a pipe cleaner or ruler)
Materials Needed
Random lengths of string (5 to 10 per student), pipe cleaners (or rulers)
Procedure
Opening to Lesson
- Explain to students that sometimes we do not have a ruler handy, but can still measure or compare lengths of items based on something standard.
- In this case the standard is a pipe cleaner.
- Give every student a pipe cleaner.
Body of Lesson
- Give students ten different lengths of string.
- Tell them to use the pipe cleaner as a guide to see which ones are shorter or longer and then arrange each length on their desk from smallest to largest (shortest to longest).
Closing
- Check student work.
- As a challenge activity have students join in groups of four and arrange all the lengths in order from longest to shortest.
Assessment & Evaluation
The students will accurately arrange pieces of string by length using only a pipe cleaner as a comparison measure.
Modification & Differentiation
Special needs students may be given extended time or fewer pieces for comparison.
