Grade 4 Math Teacher Resources: Angles — Games, Activities and Exit Tickets

Learning Objectives

• Describe an angle as an amount of turn, and name the arms and the vertex.
• Identify and name acute, right, obtuse and straight angles.
• Estimate the size of an angle using 90° and 180° as benchmarks.
• Measure angles to the nearest degree with a protractor.
• Find a missing angle when angles join to make a right angle (90°) or a straight angle (180°).

How to Use This Resource

• Angle Hunt: Fold a scrap of paper in half, then in half again, to make a right-angle checker.
• Angle Snap: Deal all cards face down.
• Simon Says Angles: Say "Simon says make an acute angle" — students show it with their arms.
• Exit tickets: hand out in the last 3–5 minutes and sort into got it / nearly / not yet.

Differentiation

Support: Use the paper right-angle checker for every question before naming the angle. Challenge: Introduce reflex angles (more than 180°) and measure them as 360° minus the small angle. English language learners: Pair words with gestures: arms open small (acute), arms in an L (right), arms open wide (obtuse), arms in a line (straight).

Teacher Tips

Make the right-angle checker in lesson 1 — students use it all week. Estimation first, measuring second: it stops most protractor errors.
