Inexpensive handheld math computers like the Ti-84 series of graphing calculators came of age in the early 1980s and revolutionized the teaching and learning of mathematics. The youngest child in the family, the Ti-84 Plus CE , is still a standard classroom tool, and a powerful one. While Desmos is the only graphing calculator tool allowed for use on the SAT, the Ti-84 Plus CE is the best of many calculator option for the ACT. “Y1Y2” is one the most helpful “cool calculator tricks” the Ti-84 Plus CE can perform, leveraging raw computing power to solve equations by graphing. To solve any equation on the ACT using the Ti-84 Plus CE: 1. Set Y1 equal to the left side of the given equation to be solved, and Y2 equal to the right side.  2. Hit the graph button, and make sure both graphs appear in the viewing window.  3. Note the coordinates of the points of intersection. The x-coordinate(s) will be the given equation's real solution(s). It can sometimes be hard to finagle the graph...

Success in mathematics is rooted in efficient reading. Most math mistakes on the SAT/ACT are, in fact, reading mistakes! Learning to avoid them is an opportunity to quickly and significantly boost scores without learning any new math. Four simple strategies help ensure students aren’t misreading math questions or failing to catch important information. The Middle Lane The most effective way to prevent reading mistakes is to slow down a little. It’s counter-intuitive, but slowing down can actually help one move more quickly through the test, since doing so leads to better comprehension, less confusion and stress, and far less re-reading. All this contributes to stronger SAT/ACT math scores. A comfortable, moderate reading pace is the goal. The middle lane of the freeway. Not too fast, not too slow. Students should no faster than they can fully understand what they're reading.  Read Party-By-Part When reading gets tough, the best thing to do is slow down, read each sentence pa...
