We are currently learning about measurement in maths.
We have been focussing on:
- Measuring accurately
- Comparing lengths
- Deciding the appropriate unit of measurement to use
- Converting units of measurement
- Understanding perimeter and area
- Calculating the perimeter and area of regular and irregular shapes
- Identifying when you might need to know the perimeter or area of something
- Using efficient addition skills to calculate perimeter
- Using multiplication to calculate area.
Students have been participating in a variety of collaborative, open ended, hands-on tasks over the past week.
In groups of four, students researched the lengths of a variety of snakes. Using measuring tapes, rulers, newspaper and tape, students created their own snakes with exact measurements. Students had to label each snake with the correct measurement and covert the unit of measurement using millimetres, centimetres and metres.
Playing with Perimeter:
In groups of three, students designed and created a shape (either regular or irregular) using masking tape on their tables. They had to calculate the perimeter of their shape by adding together the lengths of all sides. Students then travelled around the classroom measuring and working out the perimeter of their peers’ masking tape shapes.
Students estimated the perimeter and area of their right foot, and then investigated the actual measurements. To do this, they traced their foot onto 1cm grid paper. To calculate the perimeter, students used ribbon to go around their traced foot and they then measured their ribbon with a ruler or measuring tape. To calculate the area, students worked out how many 1cm squares were on the surface of their foot. It was interesting to see how the estimations and actual measurements compared!
