### PRODUCT DESCRIPTION

This is a set of 24 task cards designed to give students practice finding the surface area of a 3 dimensional shape. It includes rectangular prisms, cubes, cylinders, square pyramids, and triangular pyramids. Eight of the 24 of the shapes (rectangular prisms and cubes only) are shown in 3D form. The remaining 16 shapes are shown as nets. Students need to be able to find the area of squares, rectangles, triangles, and circles in order to be successful. I have these listed as applicable to both 6.G.4 (cards with the nets open) and 7.G.6, which both include finding the surface area of a 3D shape, although several shapes do include circles which goes beyond the grade 6 core standard.

I teach above level 5th grade math and I designed these to use with my students as additional practice. I have students who are confusing volume with surface area, and who are having trouble "seeing" the faces of the shapes when it's given as a 3D image and not the net. I do allow kids to use calculators, but all of the shapes would be feasible for kids to calculate without a calculator (using 3.14 for pi).

I usually run off multiple sets of the task cards and have kids work in partners together to solve the problems while I work with a portion of the class. These could also be used for a math center. One of the benefits I have found since creating cards like this is that if a student is absent, it's really easy to send home what they missed (one set of cards and a recording sheet-- done). I also try to be careful with distractors and put answers in that address some of the common mistakes kids make.

This is an 8-page PDF file that contains 6 pages of task cards (4 per page for 6 pages), a 1-page recoding sheet, and a 1-page answer key. I included a list of the numbers that were added together to get the total surface area to show each face on the answer key.
