Due to new additions made to the curriculum, students may find themselves struggling with more formulae and equations. Accordingly, the operations on the measurements like the area are replaced by the surface area. Cube, cuboid, and sphere replace square, cuboid, and circle respectively. The introduction of the third dimension names solid geometry as the study of 3D figures too. Solid geometry is the study of solid shapes or 3D figures. Then have students share their work.After studying 2D figures like rectangles, squares, and other polygons, solid geometry is next in the curriculum. Mathematical Practice 3: Construct viable arguments and critique the reasoning of others.ĭuring the discussion, if there is any disagreement about whether a figure is a net of a cube or a prism, put students in groups to check. Have students create cue cards to refer to throughout the presentation in order to lessen anxiety and reliance on memory. Provide additional opportunities to rehearse what will be presented.Assign different presentation-related roles to group members (materials management, note-taker, director, etc.) who are less comfortable. Present to a partner or smaller group rather than the whole class.Allow an alternate means of making the presentation such as a video or audio recording.Offer students alternate means of demonstrating an understanding of the skills and concepts. SWD: While all students should be working on speaking and listening skills, some students with disabilities may be reluctant to speak in front of peers. In the discussion, bring out the fact that although nets for the same rectangular prism can look different, the nets will always have the same number of square units, so the surface area will always be the same. Be sure to have students who used different nets for the same rectangular prism present. Then have students give their presentations.
