Geometry sessions: 2nd term
During the second term 1st graders have been learning new vocabulary and concepts about shapes: 2 DIMENSIONAL & 3 DIMENSIONAL SHAPES.
The first weeks we´ve remembered the 2d shapes: circle, square, rectangles, triangle and diamond, and also their main characteristics: sides and vertices.
The rest of the term we´ve been learning some 3d shapes: sphere, cube, cylinder, cone, rectangular prism and triangular prism; and also some of their main characteristics: faces, edges and vertices.
We have practised different oral structures to talk about shapes:
– This is a circle/square/….sphere/cube…
– The circle has got 3 sides / The square has got 4 vertices….
In fact, they are becoming in little experts about this theme!
