Friedrich Froebel invented kindergarten in approximately 1837. I became aware of this and of Froebel gifts, which are wooden blocks as a result of this outstanding article by Paul Tice. Turns out as you will see in the video that Froebel used the blocks to teach young children about 3D.
He believed that the first step in learning was a progressive process that began with perception. I think there are some very important lessons that we can all learn from Froebel’s approach to education.
