A complete formative lesson with embedded slideshow, mini-lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.
Solve It! A sailboat and an accurate model of the boat are shown. How many feet long is the model sailboat? Enter only a number.
Explain your reasoning.
Vocabulary: Define similar figures your own words.
Problem 1 Got It?
Problem 2 Got It? Create a diagram on the canvas to represent the scenario. Remember that you can insert pictures of objects -- like a man, a flagpole, a shadow, etc. -- instead of drawing them all. Be sure to label all important information.
Problem 2 Got It? A man who is 6 ft tall is standing next to a flagpole. The shadow of the man is 3.5 ft and the shadow of the flagpole is 17.5 ft. What is the height of the flagpole?
