A fun way to measure the perimeter!

Hi everyone! J Today I am going to talk about a task that can be really useful when we are studying the perimeter of the figures. The only materials that we need are ropes and laces. It is a good idea to ask the children to bring their own resources, but the teacher can have some extra material just in case.

First, the teacher can organize the class in little groups composed of 4 or 5 students in order to implement the cooperative methodology. After that, each group will have some flat geometric figures in their tables and they have to measure their perimeter. These figures can be made of cork. But how are they going to do it? Well, they will do so using the ropes and then measuring the piece of string that corresponds to the outline of each figure.

I think it is not a difficult task to carry out in class and it can be really interesting for children. After doing the activity, their concepts about perimeter and area will be clarified and they will clearly see the different between both things. So I pretty recommend this activity for your class!
