This is a hands-on activity that can be used to teach linear transformations in an Algebra 1 class. Students will be able to describe the three types of linear transformations - translations, rotations, and reflections. They will use objects (pennies, bolts, beads) to graph lines and move the objects to see the transformation. This is a step-by-step activity that asks questions along the way. I included a step to have students take pictures of their grids (using a digital camera) for engagement.

This product contains a unit on matrices at the precalculus level. There are fill-in-the-blank style notes that you can print and copy for your students. I've included answer keys for all notes, worksheets, and the quiz. Here is a list of topics in this product: Matrix operations - addition, subtraction, multiplication Matrix transformations - translations, reflections, rotations, dilations Solving 3 variable systems using reduced row echelon form and augmented matrices Determinants and inverse

This is a geometric construction project in which students use a compass and straightedge to construct many different geometric figures. Students will construct, among other things: Napoleon's Triangle Theorem Euler Line Inscribed Dodecagon 9 Point Circle Kite Inscribed Pentagon Divide a segment into 7 congruent segments Construct a 75 degree angle I have also included a help sheet with step- by-step instructions for each construction and an example of a completed project. I used this in my 9t

This is an Algebra 1 lab that I have created called the "Raven and the Jug Lab". It is based on the story of the Raven and the Jug (http://www.taleswithmorals.com/aesop-fable-the-crow-and-the-pitcher.htm) Students fill a glass jar halfway with water, measure the height, add marbles, measure again, and repeat the process by adding the same number of marbles each time. They stop when their water jar is almost full. The data ends up being roughly linear. Students then write up a lab report about t

These are notes that you use to teach square roots. The notes include radical symbol, radicand, perfect square, and estimating square roots. Dan Boughner
