Are your students struggling to evaluate trigonometric functions of quadrantal angles? This Odd One Out Activity will give them plenty of practice and highlight common errors made while trying to work these types of trig problems.

# Odd One Out

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. Reference Angles Activity Instructions Determine which angle of the four given angles has a different reference angle than the other 3 angles. In other …

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. Three of the angles are coterminal angles (meaning they share the same terminal side when sketched in standard …

I created this odd one out chemistry activity to give my students practice determining how the placement of an element on the periodic table tells us about how an element will likely behave. For this activity, students were given three elements to locate on the periodic table. Based on these locations, they had to determine …
