# Hopping Into Measurement

Your students will jump into maths concepts like measurement and comparison with this delightful investigative activity! How far do kangaroos jump? Pretend to be a kangaroo and find out!

Which set of standards are you looking for?

Students will be able to use appropriate vocabulary to compare measurements of length.

(5 minutes)
• 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.
(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.
(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.
(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.
(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.
• 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.
(5 minutes)
• 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.
(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.
