• Math~ Amanda LaTurner I watched Learning Math: Number and Operations; Video 9: Fractions, Percents, and Ratios. The video began with the students creating models to investigate multiplying fractions, They created arrays in a similar way to multiplying whole numbers. The video then worked with percents as ratios (out of 100) and went on to create proportions to solve percent problems. The next portion showed the Fibinaci Sequence using the nautalus and a pineapple. Students measured the rectangles created and found that there was a constant ratio between the length and width of the rectangles. Lastly, the video showed this ratio creates the Golden Rectangle or Golden Section. Several pictures of buildings allowed students to see that ratio in structures throughout time. The author pointed out that the Golden Rectangle is comforting because people see what they think they ought to see. This was primarily a math content lesson. It could become an integrated lesson be including an art standard about form. The product could be to create a building incorporating the Golden Rectangle. It would be interesting to allow 2D as well as 3D products.
