Standards
Cluster: Solve real-world and mathematical problems involving area, surface area, and volume
Standard: Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.
Degree of Alignment: 3 Superior (1 user)
Cluster: Solve real-life and mathematical problems involving angle measure, area, surface area, and volume
Standard: Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
Degree of Alignment: 2 Strong (1 user)
Cluster: Mathematical practices
Standard: Construct viable arguments and critique the reasoning of others. Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments. They make conjectures and build a logical progression of statements to explore the truth of their conjectures. They are able to analyze situations by breaking them into cases, and can recognize and use counterexamples. They justify their conclusions, communicate them to others, and respond to the arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose. Mathematically proficient students are also able to compare the effectiveness of two plausible arguments, distinguish correct logic or reasoning from that which is flawed, and—if there is a flaw in an argument—explain what it is. Elementary students can construct arguments using concrete referents such as objects, drawings, diagrams, and actions. Such arguments can make sense and be correct, even though they are not generalized or made formal until later grades. Later, students learn to determine domains to which an argument applies. Students at all grades can listen or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments.

Cluster: Mathematical practices
Standard: Reason abstractly and quantitatively. Mathematically proficient students make sense of the quantities and their relationships in problem situations. Students bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents—and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved. Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects.

Designing Candy Cartons (Grade 6): Students represent three-dimensional candy cartons using nets. They design a box to fit a given an upper limit (the total surface area must fit on a single sheet of paper) that will hold a given volume of candy.
Students are required to draw either an accurate full sized or scale drawing net including flaps necessary for carton construction.
After completing the task, students can analyze sample student work to deepen conceptual understanding.

Applying Angle Theorems (Grade 7):
Students use geometric properties to solve problems. The assessment problems provides information about students understanding of geometric properties. Misconceptions are addressed as students analyze peer solutions. Analysis of student work incorporates Standards for Mathematical practice 3: students critique the reasoning of others.
