ESCOLA SADAKO
BARCELONA

Activity addressed to 6th graders

Purpose:

· To identify prisms, pyramids, cylinders and cones
· To find relations between faces, edges and prisms
· To distinguish regular polyhedrons
· To recognise solid 3-D shapes from its folding
· To acquire strategies for problem solving
· To identify Geometry from the environment

Materials:

· Plasticine, toothpicks, polyhedrons, a camera and a computer

Vocabulary:

· Prism and pyramid
· Cylinder, cone straight cylinder, oblique cylinder
· Face, vertex, edges
· Triangular, cuadrangular, pentagonal and hexagonal prisms
· Triangular, pentagonal hexagonal and octagonal pyramids

 

Development of the lesson:

· From some views build up the figures. Explanation of Geometry: origin and brief story.
· To remember basic concepts writing a summary of what children already know: vertices, regular and irregular polygons, faces, edges…be able to recognize them.
· To build up a solid figure with toothpicks and plasticine.
· To practise how we can draw 3-D prisms and pyramids on a paper
· Geometrical itinerary in the surrounding area of the school taking photos, printing them and focussing on the geometrical concept. Create a wallchart.
· Take the younger children (3rd grade) to the surrounding area of the school acting as guides and telling them what they have previously observed and learned.
· To work on the definition and the study method
· The assessment has two parts: a written task where children have to define and write the names of the solids and the oral task where they have to choose the solid mentioned by the teacher out of the box.
