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 practice activity for using the quadratic formula to find complex roots. Students will solve problems and color in corresponding images on a bingo card according to their answers. The images and bingo cards come from crayola.com (link provided).

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.

In this lab students will be determining the formula for the volume of a sphere in relation to the volume of a cylinder using play dough. I created it for my standard and honors 8th grade math classes to give them a sense of where the sphere's volume formula comes from. This works best in more advanced classes, but is accessible to any student with the right groupings and support. My students loved that they got to play with play dough for this one. It really got them engaged and having good co
