Geometry is looking carefully
The lid of a pot is round, the door is a rectangle, the roof resembles a triangle. On this trail, you learn to recognize these shapes, to draw them and to measure them. Each class has pictures to play with and a challenge at the end.
Discoveries itinerary
- 1st and 2nd years: recognize flat shapes in objects and drawings; separate straight and curved lines.
- 3rd year: count sides and vertices; compare figures; discover parallel and perpendicular lines.
- 4th year: understand the angle as a turn; find right angles and axes of symmetry.
- 5th year: measure perimeter and area on the mesh; Zoom in and out of figures while maintaining their shape.
How to enjoy each class
- Note: look for the form of the lesson at home or at school.
- Stir: use the interactive figures and see what changes.
- Draw: repeat on the graph paper what you discovered on the screen.
- Explain: tell someone why your answer is right.
There are also geometry classes on the [Natural Numbers] track(/en/posts/basic/natuais/fundamental-1/), that link shapes and counting.
