The Rookery

All of the 4/5s are embarking on a new math unit. We are a few days in to examining the concepts of area, perimeter and volume. Below are some of the concepts that we will be covering. Each child will begin exploring the concepts in lessons adapted to their current level of understanding. Here are the concepts we will be covering:

*Difference
between area and perimeter

*Context
uses for Area/Perimeter

*Common
Units and Labeling

*Development
of formula for Area of a Rectangle

*Use
of Area of a Rectangle Formula

*Area of a parallelogram and area
of a triangle

*Area of irregular shapes

*Application of skills to real
life problems

*Relationship between perimeter
and area

*3-D
shape ID

*Faces,
Vertices, edges

*Volume:
development of formulas for cylinders and prisms

*Exploring
volumes for cylinders, prisms, and cones

Cycling back to mathematical concepts in multiple contexts over time allows children to go from exposure (to new math skills) to the point of mastery of concepts. The Kestrels have been actively using area and perimeter in their waaginagaan project, and have already begun to explore the many purposes for using area and perimeter. Just yesterday, I also saw my first Peep (a Peep Village mini-person) prototype, so I know the rumblings of village have already begun. All of the skills learned in this unit will be applied with great meaning during the creation of village homes, establishing of property lines, and the planning of village boundaries and public lands. 

At home this week, take the opportunity to re-inforce these concepts by showing how you have used area and perimeter at home (building projects, planning how much grass seed to use, looking at paint cans to see how many will be needed for a certain room, etc.).  – Amy B.
