Fourth graders learn the basic building blocks of geometry — points, line segments, lines, and rays — and how lines can be parallel (never crossing) or perpendicular (making a square corner).
Students will be able to…
A dot, a straight path, a beam that goes forever — geometry has exact names for all of these. What are the building blocks that shapes are made from?
Project this and tap each geometry term. Have students learn the difference between a point, segment, line, and ray!
Tap any phase to open the teacher moves and student actions.
A dot, a straight path, a beam forever — what are these called?
Teacher models.
Class uses the Geometry Explorer.
Students identify.
One figure.
Aligned to the Common Core State Standards for Mathematics.
Draw points, lines, line segments, rays, and angles; identify parallel and perpendicular lines.
Classify figures by their lines and angles.
Understand angles as geometric figures.
Attend to precision with geometry terms.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students find parallel and perpendicular lines around the classroom — in windows, floor tiles, and books. A printable geometry sheet is in the Math 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.
