WAL how to find the perimeter and area of some classroom objects.

Term 4

My Reflection

At the start I found the whole thing tricky because I had forgotten how to do the length and the breadth but at the end I found it easy.

I found measuring the length and the breadth easy to measure because at my dad would measure things a lot and he had taught me when I was little.

My next step is do more area and perimeter in my spare time.

I enjoyed measuring the objects in the class and I also enjoyed multiplting the 2 by the the centimeters that I added up.
