Discuss with the students the conditions that will make each of these relationships true. A You may have students use non-standard or standard units for measuring. As a follow-up, prepare a class graph classifying the students in the three categories. The Lilliputians' Measurements When the Lilliputians measured Gulliver for a suit of clothes, they had their own special way of computing measurements. Have students construct ratios which represent the relationships described above.
Students can collect class data, construct scatter plots, and view for correlation.
This would be a good graphing calculator activity for middle school students. The workshop provided you with a few ways to incorporate their use in the instructional program. Use the geoboards to show different ways of representing fourths and eighths. Assign a particular value to a piece of the tangram. Based on that value, find the value of all of the other six pieces.
