Quote of the Month

"The highest form of pure thought is mathematics"

Plato

What should students learn?   At the high school level, students should be familiar with the material on the ACT as detailed in this month's Recommended Reading, The Real ACT Prep Guide. On June 9, Math Confidence's Robin Schwartz will take the ACT for the very first time. Unlike the SAT, the ACT includes trigonometry -- this month's Math topic and video.
Recommended Reading  
ACTThe ACT, like the SAT, is a college admissions exam and can help fill academic gaps.   There are five sections: English, Math, Reading and Science and an optional Writing Test.
According to the ACT, this exam is for "assessing academic growth for college and career readiness".  This is the official ACT book and by next month, Math Confidence will be able to report if it is an accurate representation of the exam.  
The Math Confidence Philosophy Conclusion

The forthcoming five chapter ebook, The Math Confidence Philosophy, will focus on how to improve Math confidence and scores.  The conclusion details how viewing problems as opportunities can help people persist through the learning process. Knowing that one has done a proper day's work is what builds confidence in academics and in other areas of life.  The next ebook will expand on the Math Confidence Methodology.

The Math Confidence Philosophy Conclusion

Introduction to Trigonometry

Trigonometry is the study of how the sides and angles of a triangle are related to one another.  Right triangle trig is based on the Pythagorean Theorem and can be learned in middle school. A triangle has 6 parts (3 sides and 3 angles) but with trig if you know any three of them you can find the other three.  The ACT has real trigonometry problems while the SAT only has trig problems based on the SAT Math reference sheet that includes the Famous Right Triangles 45-45-90 and 30-60-90.
