At the heart of figuring out the surface area of a rectangular prism is knowing how much exposed area it has. The task cards also include questions on how many vertices, sides, faces, and edges the shapes have. Rectangular Prisms Surface Area of a Rectangular Prism Worksheets Develop fluency in finding the surface area of a rectangular prism, a 3-dimensional shape with six faces. You can cover the graphics for your older kids to figure out how to build the shapes themselves, and your younger kids can use the graphics as a guide. Rectangular prisms can turn into lots of different things Help your students develop an understanding of this 3-D shape while creating pictures of different objects. The task cards include both 2-dimensional and 3-dimensional shapes, so you can pick and choose which ones fit your child’s level. We have used thick black lines so that we can more easily show you what to do as a guide, but you dont need to use them if you dont want to when making your rectangular prism. You can laminate the cards and use them for geometry lessons. 1.Copy this rectangular prism template on paper, construction paper or cardboard by printing it and/or tracing it. To make building the geometric shapes easier, I have an awesome set of printable marshmallows and toothpicks geometry task cards for you to download. Off into your kids’ bellies they go! Building with Toothpicks and Marshmallows Printable Use this printable pattern with your students to help them construct their own rectangular prism to demonstrate their understanding of geometric shapes. Plus, it doesn’t hurt that sometimes you find marshmallows that are too small to use for building shapes. If your kids are resisting learning geometry, this is the way to introduce 2D and 3D shapes to them! My kids jumped on this activity right away and wanted to build all kinds of structures with marshmallows and toothpicks. For kindergarteners and first graders, you can explore 3D shapes like different prisms and pyramids and count how many faces and edges each shape has. For preschoolers, you can teach them basic 2D shapes like triangles, rectangles, and squares, and even introduce to them the concept of sides and vertices (corners).
