P Ī T A U 1 - 2019
This term in maths Mrs Togiaso's group have been learning about perimeter and area. As a class we discussed why we would need to understand these concepts and thought of what situations we might need to use this type of maths.
Some of our ideas about perimeter included:
- If you were trying to measure the running track for the cross country
- If you wanted to know how many metres it is around the outside of a netball or basketball court
- If you wanted to paint the outlines for a 4-square court
Dominic shared how you might need to measure the perimeter of different things if you wanted to build a house so that everything would fit. He then shared how his dad, sister and himself were building a tiny house and how there was so much maths involved in this project.
We then searched for images of tiny houses on Google and discussed the differences between them and normal sized houses. Many of the class were really interested in this topic so we decided to design our own tiny houses.
First we brainstormed all the different zones/ areas we would need to include in our design. Then we used grid paper and measured up the rectangle (10cm by 16cm). Next we used Sharpie to draw in the various zones and coloured these each a different colour. While we did this part Mrs Togiaso took maths workshops on different addition strategies that we could use when we were calculating perimeter.
We then chose 4 zones to focus on and measured the perimeter of each. We recorded the measurements of each side in a number sentence and then used the strategies that we'd learned during our workshops (e.g. doubles, making 10 and place value partitioning) to find the perimeter of each zone.
After this we learned about area and how we can use multiplication to find the area of rectangles and squares. We practised finding the area of different shapes by counting the number of squares inside a rectangle/ square. Some of us also used our knowledge of multiplication to calculate the area of shapes that weren't drawn on grid paper.
Finally, we designed some landscaping for the outside of our tiny houses and used our maths skills to calculate the area of different zones in the garden.
