Lesson 17 continues which is looking at division of fractions in a visual way. Then we did Lesson 18, which is actually the homework of the children of one of the participants.
We went on to Lesson 19 on area. Today we did some work on measurement.
Lesson 20 revealed an interesting pattern! Who would think that the area of the polygon is realted to the number of dots inside it. And the relationship that someone came up with (add the number of dots minus three) is awesome!
George Pick would have been impressed. The link to Pick's Theorem is available above.
We had been focusing on whole numbers and fractions the last few sessions.
We also used graphs to document the number of 'pegs' for good ideas. That is Lesson 21.
Selamat Hari Raya to all. Final session for EDU330 on 31st August. But the learning journey continues ...
