One of the teachers at my school was having trouble finding some 3D geometric shapes to make her test with, so I made a few for her. Then one thing led to another, and now I have a whole bunch of clip art that I thought a Math teacher might find useful. I have used these images to create tests, task cards, scavenger hunts, and practice work for Math small group and centers. This file is not meant to be used as a presentation. The idea is that you can copy/paste whatever you need from here a

This worksheet is intended for use after students have learned the basics of writing equations in slope-intercept form. Students will: 1) Write an equation for a line with a given point and y-intercept. 2) Write an equation for a line passing through a given point with no set y-intercept 3) Estimate the slope of a line when given no grid lines on a graph. This PowerPoint file is intended to be printed as a worksheet rather than as a presentation.

This is sort of an exploration type activity to help students become more familiar with the window and trace functions of TI calculators. The questions are all application type problems and my goal was to create a worksheet that would let students go at their own pace without me giving direct instruction that was either too fast or too slow for them. File includes: 4 worksheets to be used with TI Graphing Calculator and detailed answer key. I found that letting students work with a partner

This Scavenger Hunt contains questions to allow students to solve systems of equations by graphing them. Other methods can be used, but these questions were designed to be work on graphs that go from -10 to +10. -------- What is a Scavenger Hunt? A scavenger hunt is a more engaging and mobile alternative to just giving the students a worksheet. To use the scavenger hunt: 1) The slides are currently in order so that the question on the bottom half of each slide is answered on the top half of

This was intended to be an introduction to graphing linear equations and function notation. Students create and graph linear functions to represent an asteroid falling to earth as well as functions for different missiles they can use to intercept it. The first file is the student worksheet and the answer key. Print the first slide for the students to use to show their work. The second file is an animated presentation that shows what the students are working out on their papers.

This is an Algebra worksheet over finding equations of parallel lines. Some problems require students to find the equation of a line from a graph and others require students to use their algebra skills to change an equation from non-standard form into slope-intercept form. They then find a parallel line from a list of possible equations of lines. As students complete the exercises, their answers will fill in a joke at the bottom of the page. This makes the worksheet a little less boring

This was a worksheet I made as my 1st lesson on graphs of quadratic functions. I started out the lesson by showing students the basic form of y=x^2 equations and what they look like on the graph by doing the 1st problem. After having them graph it, there is no trouble finding someone who can explain/guess how to make the 2nd graph (y=-x^2) For the rest of the worksheet, I make sure they know how to use the table function on the calculator and then leave them to work in pairs or small groups.

This Scavenger Hunt contains questions designed to give students practice solving systems of equations using the Substitution Method. -------- What is a Scavenger Hunt? A scavenger hunt is a more engaging and mobile alternative to just giving the students a worksheet. To use the scavenger hunt: 1) The slides are currently in order so that the question on the bottom half of each slide is answered on the top half of the next slide. 2) Print out all the slides and post them up randomly around t
