This 5-day project-based math resource applies math concepts in a real-world scenario to teach students about measuring and drawing angles. In this 5-day unit, students will use their knowledge of geometry and angles to design a playground. This math project is engaging and authentic. Plus, it’s available as both a digital and print resource.
This project-based math resource is aligned with the following 4th Grade Math Common Core State Standards:
Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.
An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
This resource is available in both Printable & Digital Google Slides versions.
What’s included in this resource:
