High School Geometry Proofs with Similar Triangles
The biggest hurdle for high school geometry students when they reach this unit is the persistent, stubborn belief that if two triangles have the same angles, they must be identical in size. They spend weeks drilling congruence, and suddenly, we ask them to accept that... read moreAlgebra 1 Help for Understanding Function Graphs and Key Features
I was looking over the progress reports for our Algebra 1 students, and it occurred to me that we have several pupils who could use a reset on how algebraic equations translate into visual shapes. If you are supervising independent study or helping a student who... read moreTeaching High School Algebra 1 Statistics
A parent once asked me why their teenager insisted on using the mean for every single data set, even when an extreme value skewed the results and made the answer look ridiculous. It is a common frustration for teachers. Students learn the mean early in their... read moreTeaching High School Geometry Right Triangle Applications
Applying trigonometry to real-world scenarios requires students to think beyond the textbook. When students transition from theoretical math to practical application, they often face challenges in identifying triangle sides correctly, which this lesson helps... read more
