This lesson is used to define the term line segment. Students create a shape design behind a barrier of some kind and then give directions to a partner to help the partner recreate the design. This activity reinforces geometry and positional vocabulary. Students are introduced to the term symmetry as they try to exactly match the missing other half of a drawing that has been reproduced for them. Students trace a shape upon a point of rotation and describe what they notice about the resulting design.
Students blow bubbles with a bubble solution and measure the diameter of the bubble they have blown.
By investigating a variety of bubbles they will find that the distance around is a little more than 3 times the diameter. Grades 1-6 . Math Solutions Publications. 3 Burns, Marilyn. About Teaching Mathematics .
