Linear+Functions+2011

Calendar


 * Day 1 (Monday Jan. 3rd and Tuesday Jan. 4th): Use coordinate geometry to solve problems - specifically midpoint, distance formulas and Pythagorean's theorem.**


 * Bell Buzzer (you will need graph paper, ruler and two markers/colored pencils)
 * 1) Draw an x and y axis on your graph paper, through the middle. Use the whole page.
 * 2) Plot the following points A(-2,5) B(4,2) and C(-1,-6)
 * 3) Using a ruler, draw a triangle with your coordinates.
 * 4) The formula for a triangle is A = 1/2 bh. How are we going to find the area of the triangle without using the ruler to measure the sides?
 * 5) Ask your new group members to share with you one thing they did this break that was interesting/fun/adventurous.
