During math this week we used manipulatives to calculate perimeter and area. The students used pipe cleaners to make triangles of different sizes, then measured the perimeter. We discussed the differences between Equilateral, Isosceles, and Scalene triangles.
The students used Geoboards to make rectangles with a perimeter of 12, 14 or 16 units. They learned that there are multiple ways to make this happen. When we changed the scale to 1/2 unit between pegs, the students were able to make rectangles with odd numbered perimeters.
Using Pattern blocks, the students measured area by tiling rectangles. We discussed how larger tiles cover more area, and it takes fewer tiles to cover the area. It is easier to use larger tiles or materials to cover a floor, wall etc, because it requires less time and work, but it does mean that some of the tiles will need to be cut to fit the corners of a room, just as we could not cover our rectangles completely with whole shapes unless they hung over the edge of the rectangle.
The students worked hard, checked each other's work, and did a good job helping each other.
