With these three minilessons, you can help your students master the vocabulary necessary for 3d shapes. One activity has the students matching terms like face, edge, and solid with each definition. Another activity shows pictures of 12 different solids and nets that the students must rearrange in order to match the pictures with the correct names. Finally, there is an empty Venn diagram with pyramid written in one circle and prism in the other. Having students take turns filling in different portions of the Venn diagram will help ensure that they understand the attributions of each.
