6-8
In this lesson, students investigate relationships between numbers, identify number patterns,
represent the information in graphic chart form, and generalize the results of an investigation. Specifically, students explore the relationship between a whale's length and its weight.
6-8
In this lesson for grades 6‑8, students participate in activities in
which they focus on patterns and relations that can be developed from
the exploration of balance, mass, length of the mass arm, and the
position of the fulcrum. The focus of this lesson is the relationship
between the length of the arm and the mass of the objects.
6-8
Using the story "The Celebrated Jumping Frog of Calveras County" by Mark Twain, students simulate a jumping-frog contest and determine the distances "jumped." The students record the distance of individual jumps in centimeters and determine the total distance jumped (the sum of the three separate jumps) and the official distance (the straight-line distance from the starting line to the end of the frog's third jump). The students compare the range and median of the total distances with those of the official distances of the group.
6-8
Students measure distances using standard and nonstandard units and
record their measurement in various tables. Then they are asked to use
descriptive statistics to report the results. During a top-spinning
contest, students measure the distance along a curve using indirect
measurement. They record the data for their group in a chart, and
compute their individual median and the group median.
6-8
This lesson sets the stage for a discussion of travel in the solar system. By considering a real-world, hands-on activity, students develop their understanding of time and distance. Finally, students plot the data they have collected.
6-8
Students participate in an activity in which they develop number sense in and around the shopping mall. They solve problems involving percent and scale drawings.
6-8
Students time balls rolling down inclines of varying lengths and
heights, then try to make inferences about the relationship among the
variables involved. Students decide which variables are important (and
can be measured), how best to collect the data, and how to interpret
the data. This lesson plan is adapted from an article by Thomas
Edwards, which appeared in the November - December 1995 edition of
Mathematics Teaching in the Middle School.
6-8
This lesson introduces relationships between measurement and geometry. The activities build on students' prior knowledge as students work with partners and as a whole class to identify and classify terms to develop their understanding of measurement.
6-8
Students learn about ratios, including the “Golden Ratio”, a ratio of length to width that can be found in art, architecture, and nature. Students examine different ratios to determine whether the Golden Ratio can be found in the human body.
6-8
Students learn to write and solve proportions by gathering data and calculating unit rates.
