The benchmark(s) of focus is the primary focus for student learning and instruction to be taught or reinforced and provides an intentional opportunity for students to work with that concept or skill.
MA.912.GR.4.1
Identify the shapes of two-dimensional cross-sections of three-dimensional figures.
Clarifications:
Clarification 1: Instruction includes the use of manipulatives and models to visualize cross-sections.Clarification 2: Instruction focuses on cross-sections of right cylinders, right prisms, right pyramids and right cones that are parallel or perpendicular to the base.
Supporting benchmarks either make a connection or may help students achieve the focus benchmark(s) and increase students’ opportunities to make connections within the subject or to other subjects. The information included in this section is not a comprehensive list, and educators are encouraged to find other supporting benchmarks.
MA.7.GR.2.1
Given a mathematical or real-world context, find the surface area of a right circular cylinder using the figur...
Clarifications:
Clarification 1: Instruction focuses on representing a right circular cylinder with its net and on the connection between surface area of a figure and its net.
Clarification 2: Within this benchmark, the expectation is to find the surface area when given a net or when given a three-dimensional figure.
Clarification 3: Within this benchmark, the expectation is not to memorize the surface area formula for a right circular cylinder.
Clarification 4: Solutions may be represented in terms of pi (π) or approximately.
