Lesson 10 Worksheet 1: Three Squares Bisecting Diagonal Line
How we think and communicate is closely related to how we use language.
Taking care to use language clearly and avoid fuzzy language, such as overgeneralizations,
helps us communicate what we want to communicate.
Sometimes, such as when we give directions, we need to be precise.
Give the following directions to the class:
Draw a diagonal line from the upper left corner to the lower right corner
of
your sheet of paper. Draw three squares bisected diagonally by the line.
The lower right one is largest; the upper left one is medium-size; and the
one in the middle is smallest.
Allow time for the students to follow the directions, and ask for volunteers to
share their drawings. Point out that all directions need to be given at one
time. Why? What would happen if only partial information was given?
Have students discuss consequences of attempting the task before complete
directions have been given. If they fail to grasp the rationale through
discussion, have them experiment with giving partial directions and discuss
results
