Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.
1 interactive, auto-graded activity for 7th grade students practising 7.G.A.3. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Interactive cross-sections activity for 7.G.A.3. Students slice rectangular prisms and square pyramids, name each 2D cross-section, and compute its dimensions from the solid's measurements. A move-the-plane slider lets them explore before committing, with answers revealed only when correct. Includes curved-solid extensions. Self-checking and no-prep.
