We have started our geometry and measurement unit. First up? 3D objects!We are talking about and looking at the sides, edges, corners, etc. of 3D shapes and finding lots of classroom objects that are similar. We have been using words like straight, curved, point, top, corners, edges, hollow, solid, roll and flat in order to play I spy and to explain sorting rules. We have noticed that some 3D shapes have triangles, rectangles, circles and squares on their sides! Can your child point out the cylinders, cones, cubes and rectangular prisms? Wow!Here are some videos that help reinforce shape concepts and vocabulary: http://www.youtube.com/watch?v=hYaQoBilylshttp://www.youtube.com/watch?v...
