Drawing different types of squares was easy. However, finding the area of each was interesting. Some squares needed to be cut and pasted to form a whole or half of the square to find the area. Or it is the half of something that needs to be joined to see the whole. Lastly, when working with polygons, a bigger shape was needed to cover the irregular polygon. Taking away unwanted area revealed the area of the polygon. There is no one-way to work it out. As long as I can make sense of the shape and work out to find area it can be correct, I think. Knowing the area of a square and using it to work out the area of a polygon is very engaging. Very keen eyes and relating the shape is important to get the shapes and it's area.
Pick’s theorem is not so clear to me. I need more time to work on it to further understand the way it works.
