As a math teacher, you likely find yourself searching for activities to accompany your textbook and slideshow lessons. After all, most of us remember concepts best when we get hands-on with them. When it comes to teaching students about arcs and chords in circles, it can be particularly challenging to keep things engaging.
Here are some activities to help you teach students arcs and chords in a fun and meaningful way!
1. Use a Hula Hoop
Using a hula hoop as a model during your lesson on arcs and chords can be super helpful. Students can physically see how the diameter of the hoop creates two equal arcs. With a partner, each student can experiment holding the hoop in different ways and forming new chords. This activity encourages students to think about the relationship between the radius and chord length.
2. Use Pizza Pie
Another fun way to teach students about arcs and chords is by using pizza pie. This tasty activity teaches students about the measure of the central angle the arc creates. The next time you have pizza in class, give each student a slice and have them measure the central angle formed by the two radii. Bonus tip: let them eat it afterward!
3. Create a Geometry Diagram Puzzle
Creating a puzzle out of geometric diagrams is both entertaining and educational. Students must arrange and connect diagrams of circles in the correct alignment. For a challenge, make the curve sizes slightly different to simplify arcs or chords.
4. Play “Name that Shape!”
Another fun activity to teach students about arcs and chords is “Name that Shape!” Give out pictures of different shapes along with the instructions to mark where the arc and chord are. Students can then present their drawings to the class, and their peers can identify the arc and chord for each shape.
5. Shape Tracing
Shape tracing is a simple activity for younger students that still educates students about arc and chord measurement. Give students a template of a circle with a dotted line tracing its path. Students can trace the path and measure the length of the chord the circle’s diameter forms.
Conclusion
Arcs and chords may seem like they require a lot of memorization and not enough hands-on activities. But there are plenty of creative activities to help students understand and engage with these important mathematical concepts. With these activities, your students can have a lot of fun while also learning about arcs and chords!
