This is a ready-made unit plan, allowing for approximately six weeks of contact time in the classroom, 10 lessons in total, that explores all things numbers with your students. It is over 80 multi-layered slides that will engage every learner as they present each topic (rational numbers, irrational numbers, exponents, scientific notation) from several different perspectives. These are not your ordinary slide presentations. They are fully interactive, ensuring no boredom in the classroom, either

Using their trigonometry skills, students are going to determine how often any one key, or note, is played on a standard 88 key piano (keyboard). Your students will first need to find the common ratio between all the keys (the 52 white keys and the 36 black keys). Then, they will narrow down further by using the common ratio that was found to determine the use of higher or lower frequencies. The final step will be to create a sin function to find the constancy of use of any note(key) on that st

In this activity students will learn how linear systems can be used in a business to predict at what point the business will break even after any projected costs. The learners will use all three methods of solving a linear system to find the points of intersection, or the point at which a business will have recouped their costs, in two different scenarios. They will first consider a plan where a producer simply grows and sells unprocessed coffee beans to a distributor. Then they will be presente

Real World Application/Activity Involving Circle Theorems and Triangles A good activity for students who have a working knowledge of GeoGebra. Your students will begin in one of three dig areas in Egypt, and then, using circle theorems and triangles, will find the distance to the other two sites. Next they will choose one of the three dig sites to start, where they will find an artefact that they will reconstruct in GeoGebra 3D which will be used for their report/submission to the contracting mu

This activity uses the basic trigonometric ratio to show that it is possible for shapes to have equal measures but still have different areas. Using cell phones as an example, the students will compare two different cell phones that have the same screen size, but different aspect ratios, and prove that the same screen size does not necessarily equate to the same amount of screen area. They will find the length of the sides using all three trigonometric functions, and then calculate the area. The
