• What characteristics do parallelograms and rectangels share?
• How do rectangles differ from other parallelograms
• Why is a square always a rectangle?
• Why is a rectangle not always a square?

Using the Rectangle vs Parallelogram activity sheet carefully examine the two shapes and brainstorm their similarities and differences. Have a group discussion about the shapes attributes.

-Record thinking in the correspinding boxes on the activity sheet

-Work with a partner or small group to categorize the attributes you have listed on the activity sheet. Think: How can you group or categorize the shapes' attributes?

-Share ways with entire group

Things are Shaping Up Activity

Mentally manipulate the shapes and think about the following questions.

Do you think it will be possible to transform the shape?

Will the rectangle retain its attribute?

Will the parallelogram retain its attribute?

-Record your predictions on the Things are Shaping Up activity sheet.

Use the following website to recreate the shapes listed on the top of the sheet. As you recreate each shape, you will need to record a brief description describing the process used.
