Both of these events are due to misplacement of ladders. How do we know how to safely place a ladder? Students will use right triangle trig and the pythagorean theorem to investigate methods of setting up a ladder, sin, cos, tan, ratio, sine, cosine, tangent

Postal rates have been figured by the ounce since July 1, 1885. Students• This activity allows the students to create graphs and equations based on the price of mailing a letter up to one ounce. The explanation of reasoning pieces are important as we move to the common core and also are more aware of the importance of English results

This PowerPoint document will help students understand how to read, create and interpret Venn diagrams

Based on the data in the graph below, determine an appropriate growth model for the population of the world. Be careful about the years that you use. Remember 10000 BC could be considered -10000, or you could use 0 for 10000 BC and then adjust the other years appropriately. You should find at least three growth models and then explain which of the models is the most appropriate. Use residuals, graphs and correlation coefficients to explain why your model is the most appropriate. Linear, exp

Students often approach me with graphing calculators and say “This is broken,” or “the batteries are dead.” More often than not, the calculator is still usable. This guide should help you restore life to many of those calculators, AAA, texas instruments, TI83, Nspire
