This practice sheet covers: ~using algebraic equations to solve for missing angle measures in triangles ~Determining if triangles are congruent, similar, or neither ~Solving for missing measurements in similar triangles. It could be used as in class practice, homework, or a quiz.

This activity includes 4 problems worked out by substitution. Each problem has an error in it (problem 2 actually has two errors). I used mistakes I saw my students commonly making. The activity asks students to find the error, explain the error, then rework the problem correctly. This is a really good group work assignment as it will get students talking about common errors they make. Each group could be assigned their own problem to correct, rework, and then present. It could also be used as a

This is a one page graphic organizer I made to get all of the important parts of graphing quadratics in one place. It includes an example of the back.

I created this discovery-based geogebra activity for my standard 8th grade math class to work through the question of how changing heights and radii affects the volumes of different solids. The activity involves students changing different dimensions of solids and observing then explaining the affects the changes had. It relies on students already knowing the volume formulas and perhaps having a general understanding of where those formulas came from. This resource includes the powerpoint I used

I used this during the transformations unit in my standard 8th grade math class. I had students fill out rows as closures for class periods. It helped them to have a running list of all pertinent vocabulary with diagrams and/or examples. This could also be used as a review activity at the end of the unit before a test.
