Explanation
The teacher will have a list of vocabulary words with the definition for kids to look at in case there is any confusion. The teacher will explain to them each vocabulary word and ask if they have any questions over it. The teacher will also provide an anchor chart explaining a few of the 3D shapes that compares them to something similar they know. For example, the teacher will explain what a cone is and how it's similar to a party hat, she will then explain what a sphere is and how it's similar to a bouncing ball and so on.
