Geometry for real

This post is going to have two parts. In first place, we are going to consider the teacher’s point of view by reviewing a series of four videos that shows how can three-dimensional shapes can be learnt. The second part is going to focus on material which is directly targeted for children , that can be quite useful for them.  Solid geometry. Teacher’s scope First lesson: Introducing 3-D shapes (1) Introducing 3-D shapes in second grade. Source: Peace and Happiness Foundation I find very interesting how well organised are these videos. Very small amount of content but well learnt. In the first video they first recap what they already know (2-D shapes) and share the knowledge with others, comparing 2-D shapes they know with those new-brand 3-D shapes that the teacher is showing to them now. They repeat the concept a lot, so that the students really learn the words related (they look like quite motivated about repeating it endlessly!). After this it comes a visual
