Geometric Solids - Sensorial - Montessori

This video goes through the presentation of the montessori Geometric Solids! An absolute favourite in the Childrens House - there are soo many extensions you can do with this material!
PRESENTATION
• As you are talking to the children about these geometric solids, let them feel each one and talk about each solid if it is a sphere you can explain that is has no sides that it can roll.
• A square how many sides does it have, and that it has points.
• As you are talking about the solids you can tell them the names of each solid so they can eventually learn the names.
• Regular and curved solids:
• Sphere - All points on the surface are equidistant for the center.
• Ellipsoid - A form whose plane surfaces are either ellipses or circles.
• Ovoid - egg shaped
• Curved Solids with plane and curved surfaces:
• Cylinder - a solid bounded by two parallel planes which are curved.
• Cone - a solid with a circular base joined by straight lines to the vertex.
• Solids bound by straight lines:
• Prisms - The end face can be any regular polygon.
• Rectangles - the side faces are always rectangle
• Triangular prism - This has a triangle for the end face
• Square Prism - this has a square face on each surface
• Square Based pyramid - The end face is that of a square
• Rectangular Based Pyramid - Named by the base of the pyramid.
• This activity is a child of five years and onward
• There are a group of wooden cards that can be used when demonstrating this activity, they fit perfectly on the base of the solids that are prisms.
