Fourth graders will discover the building blocks of geometry in this unit: points, lines, line segments and rays. Students will explore the properties of different shapes, including symmetry, parallel and perpendicular lines, and 900 angles. Students will apply their understanding as they learn to sort shapes based on these properties.
Representing data on graphs makes math visual and involves some creativity and design. Plotting data using fractional units takes their learning one step further. Also in this unit, students learn to measure using both traditional units (like inches, feet and yards) and metric units, and how to convert measurements within each system. The concept of measurement gets two dimensional when students explore measuring and working with angles.
How well do you know your angles? Let's find out! Use this geometry resource to help your students identify and differentiate between important angles such as acute, obtuse, straight, and right angles.
Students get to practice measuring angles using built-in protractors in this fun geometry activity! After measuring, they'll put their angle knowledge to the test by classifying each angle as acute, obtuse, right, or straight.
Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?
