Hopping Into Measurement
Students will be able to use appropriate vocabulary to compare measurements of length.
- Tell your students that today you are going to investigate how far kangaroos can jump.
- Tell them that they will do the research, investigation, measurement, and comparison needed to figure it out.
- Let students know that this kind of project is similar to what scientists do in their field.
- Have your students brainstorm and contribute their prior knowledge of kangaroos. Record this information on the board.
Explicit Instruction/Teacher Modeling(5 minutes)
- Have two students take a step and measure their stride with a measuring tape. Label these measurements with "S" for step or stride, if desired.
- Now have two students jump forward from standing. Again, measure the measuring tape and label if desired.
- Compare the students' lengths to each other as well as between walking and jumping. Tell students that a bigger number indicates a longer stride and a smaller number means a shorter stride.
Guided Practice/Interactive Modeling(5 minutes)
- Have students work in groups measuring the jump length of their group's kangaroo. Have each group record one student's jump with a piece of masking tape or yarn.
Independent Working Time(5 minutes)
- Have students work with a partner and take turns jumping and measuring the individual jumps.
- Have each student record their jump on an index card. They may compare their measurement with their partner.
- Enrichment: Students in need of a challenge may research kangaroo jumping on the computer or provided books.
- Support: Students who need support with measurement skills may use large blocks as nonstandard measurement tools and count by blocks for length.
- Students may arrange the measurement tapes or strings from their group activity from shortest to longest.
- Students may use appropriate measurement vocabulary to report on their jump length measurement.
Review and Closing(5 minutes)
- Have students go through and circle their longest jump on the index card.
- Have your students arrange their index cards from shortest to longest jump on a clothesline or on the board.
