1 Guided Practice

Using soap bubbles and construction paper, students will blow different sized bubbles onto construction paper, measure and graph their circumferences and diameters.

2 Group Work

Activity: Investigating

Students open up shared document (Sheets) in Google Drive that will allow them to aggregate their individual data in real time...all at once.

They will use the aggregate data to generate a more accurate approximation for the value of pi.
