Good Ideas for Area and Perimeter
The activities in this book from Polygon Resources focus on the concepts of area and perimeter. The approach taken can help students use mathematical language, take responsibility for selecting materials and to develop greater rigour in their mathematical reasoning.
Paper Cut Outs asks students to investigate how cuts from a piece of paper can make the perimeter of the paper larger, smaller or leave it unchanged.
Sheep Pens is an investigation into the pen area that can be enclosed by a set number of fences.
36 Tiles is an activity in which 36 tiles are used to form as many different rectangles as possible.
Surrounding Nails is an investigation using a pin board which leads to Pick's theorem.
Pinboard Areas is an activity that can lead to finding the area of a triangle, by forming rectangles and parallelograms with elastic bands, finding their areas and any connections between them.
Diagonal Ratios is an activity designed to find a link between the perimeter and area of hexagons.
Rolling Coins is an activity which requires students to roll different coins, measure their circumference and diameter and discover the relationship.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
