This lesson comes from fourth grade math teacher, Erin Holloway. She had her students use a ruler to draw lines on a sheet of paper. Then, they measured the angles. They wrote the measurements in small print in each angle (see the close up of this in the pic). They traced their lines and added patterns. They used different things to add color: markers, colored pencils, crayons, etc. I think she had this activity in a center.
I think it would be cool to have the students select an angle measurement and write a poem about their piece that has that number of syllables. If they choose an angle with a measurement of 70, their poem would describe the artwork in 70 syllables. I would let the students help me come up with a list of common descriptive words that were off limits (beautiful, colorful, good, etc.). That way they'd be doing some vocab work.
These are visually stunning! What a great lesson!
