Second graders learn that solid shapes are built from flat faces, straight edges, and pointed vertices, and match each common solid to how many faces it has.
Students will be able to…
A cereal box has flat sides, straight edges where they meet, and pointed corners, which are its faces, edges, and vertices. How many faces does each solid have?
Project this and match each solid to its number of faces — tap a solid, then tap how many flat faces it has.
Tap any phase to open the teacher moves and student actions.
A cereal box has flat sides you can touch, straight edges where they meet, and pointed corners. Those are its faces, edges, and vertices. How many faces does each solid have?
Students match each solid to its number of faces.
Students count on real solids.
Students build a solids chart.
Students reflect on solids.
Aligned to the Common Core State Standards for Mathematics (High School Algebra II).
Recognize and describe three-dimensional shapes by their faces and parts.
Compose and identify three-dimensional shapes.
Analyze and compare shapes using their parts, such as faces and corners.
Look for and make use of structure.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students draw three solids, label the faces, edges, and vertices, and write the face count, so the parts of a solid connect to its name. A printable faces-edges-vertices worksheet is in the Mathematics library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
A quick self-check with instant feedback, drawn from this lesson’s key terms.
