Trigonometry Activities

I love this clinometer activity for giving my trigonometry students extra practice finding missing angles and sides of right triangles. Plus, it answers the question of “When will we ever use this?”

I used this evaluating trig functions square puzzle recently with my trigonometry students. We glued our completed puzzles in our interactive notebooks. This puzzle was created and shared by NCTM Illuminations under the name “Trigonometry Square.”

Check out this trig ratios puzzle which I discovered on Open Middle and transformed into a printable puzzle for my students to tackle.

Provide your precalculus students with plenty of practice converting between angle measures in degrees and radians with this degrees and radians tarsia matching puzzle.

I created this hand-on exploration for my trigonometry students to explore the question “What is a Radian?”

Help students practice converting between radians and degrees with a fun game of radians and degrees war.

This radian arts and crafts activity is designed to help students conceptually understand what a radian is. As a bonus, it creates a beautiful, mathematical art display for your classroom.

Several summers ago, I created a set of printable radian sectors to illustrate what different amounts of radians looked like when graphed in standard form.

Help your trigonometry students visualize graphing angles in standard position on the coordinate plane as well as coterminal angles and reference angles with these fun paper plate angle spinners.

This angle spinner for sketching angles in standard position is one of my favorite pages in our trigonometry interactive notebooks.

I created this coterminal angles card sort activity for my trigonometry students to complete and glue in their interactive notebooks. Students have to sort the angle cards into groups that are coterminal with one another.

I created this odd one out activity to give my pre-calculus students extra practice identifying coterminal angles. In this activity, students were placed in groups of 4. Each group was given a set of four angle cards. They must work together to determine the Odd One Out.

I created The Great Quadrant Guessing Game several years ago to give my Pre-Calculus students some extra practice determining which quadrant of the coordinate plane was represented by two trigonometric facts.

I created this fun quadrants unlocked activity to give my pre-calculus students some much needed practice determining the signs of trig functions in various quadrants.

I created a new reference angles activity using the odd one out structure to give my trigonometry and precalculus students practice identifying the reference angle of a given angle in degrees.

Looking for a visual to help your students remember the signs of the various trig functions in each quadrant? I created this set of ASTC trig posters to hang in my classroom for my pre-calculus students to reference.

Several years ago, I created this deriving the unit circle foldable for my trigonometry students to work through and glue in their interactive notebooks.

Make the unit circle memorable with this unit circle paper plate activity.

After years of seeing other teachers share pictures of the unit circle projects their students created, I decided to finally take the plunge.  I assigned my trig students the task of creating a visual representation (2d or 3d) of the unit circle in lieu of a semester test in trigonometry. Check out the results!

I created these unit circle magnets to use with my dry erase magnetic unit circle from EAI Education. I plan to use the magnets both as a way to have a large unit circle on the wall of my classroom and for various activities throughout the year.

I decided to create a Unit Circle Bingo Game to give my Pre-Calculus students some much-needed practice with evaluating trig functions using the unit circle. Technically, this is more of a game of connect 4 than bingo, but bingo just sounds more fun.

This Leap Frog style game gives students much-needed practice evaluating trig functions using the unit circle.

I created this fill-in-the-blank unit circle chart for my pre-calculus classes to use as they practice constructing the unit circle from memory.

This parent graphs of trig functions clothespin matching activity has been in the making for multiple years. Students must match each statement with the appropriate parent functions.

This Trig Mini Poster Project gives students lots of practice with graphing trigonometric functions.

This Trig Identities Challenge Activity will engage students and give them tons of practice rewriting trig expressions using trig identities.

Introduce the concept of trig identities with this hands-on trig identities matching activity.

Sarah Newton shares a fun hook for introducing trig identities – a word ladder puzzle. I have tried this activity with my students, and they had so much fun!

Use double angle identities to rewrite each expression and answer the joke of “Why was the mathematician late for work?”

I really like the simplicity of this One or Negative One? Trig Identities Task that I found in the 8th Edition of Demana and Waits’ Pre-Calculus Textbook (Section 5.1). That’s why I decided to turn it into a worksheet!
