Angles, shapes and position
Angle and shape hunt around the house
Which angles and shapes are most common in the rooms you live in?
Watch first
Learn to spot acute, right, obtuse and reflex angles anywhere.
What you need
Tick each one as you find it — 0 of 4 ready.
Stay safe: Do not climb or stand on furniture to reach a corner. Ask an adult before testing anything outside.
Plan the fair test
- Change: The room you survey
- Measure: How many acute, right and obtuse angles you count
- Keep the same: Twenty corners each time, the same card checker, the same person judging
Objectives this evidences
- Compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes
- Identify acute and obtuse angles and compare and order angles up to two right angles by size
- Describe positions on a 2-D grid as coordinates in the first quadrant, and describe movements between positions as translations
Do it, one step at a time
Step 1 of 5
- Step 1. Make a tally chart with three columns: smaller than a right angle, a right angle, bigger than a right angle.
- Step 2. Walk one room and test twenty corners with your card — window frames, chair legs, roof lines, open doors.
- Step 3. Tally each one as acute, right or obtuse, then repeat in a second, very different room.
- Step 4. Draw a bar chart of your totals for both rooms on the same axes.
- Step 5. Sketch the first room as a plan on squared paper and give three pieces of furniture their coordinates.
What should happen
Right angles win easily indoors, because building is easier with square corners. Obtuse angles turn up on open doors and roofs.
Think about: Would a playground or a park give you the same answer? Predict first, then test if you can.
Write up your result
A sentence or two is enough to save it.
