"Possibly The Best Math Chart Ever Created" But really, it is pretty cool. #math #functions
Hi, I'm teaching trig to my ("low" math group) 9th-graders, and loving it. We only had time for 1 day of trig lesson before we will have to concentrate on reviewing for the end-of-year test (after which we'll come back and do some outdoors trig/angles of elevation and depression type of stuff, leading into complicated trig word problems). The kids were awesome at basic trig! They learned how to apply sine, cosine, and tangent correctly and consistently in one 80-minute period. Rock stars, these kids. They use the tactile trick to figure out which side is opposite, adjacent, and hypotenuse, and then they use cross-multiplication to consistently and correctly solve for x. For now, since we're only learning the whole of right-triangle trig in one day, I am going to give them the acronym SOH-CAH-TOA on the exam and just require them to remember what the acronym stands for. Eventually, they'll have to memorize SOH-CAH-TOA, obviously. Anyway, totally apropos, this totally cracked me up today. Anyhow, this week is a killer. I keep trying to get ahead, but it seems impossible, as I am pulled in all directions as a teacher, a department chair, and a person soon to move across a big pond. I wonder when the next sigh of relief will come. Hopefully, there is one scheduled before July...

Las tablas de multiplicar es algo que nos aprendemos de memoria de pequeño y que debería perdurar en nuestras mentes durante toda la vida. Al igual que restar y sumar fracciones, hallar porcentajes, y un sin fin de operaciones matemáticas. Pero no siempre es así y puede que en algunas ocasiones la memoria nos falle, […]

This is a very simple matching activity where students are given a bunch of algebraic expressions (in one variable) and simplified expressions (both in algebraic and algebra tile form) and all they have to do is match up each expression with their simplified form. This is not meant to be a long or complex activity and could best be used as a warm up or end of class review or possibly just in the middle of a long class to switch up the period. MPM1D - add and subtract polynomials with up to two variables [e.g., (2x – 5) + (3x + 1), (3x2y + 2xy2) + (4x2y – 6xy2)], using a variety of tools (e.g., algebra tiles, computer algebra systems, paper and pencil); MFM1P - add and subtract polynomials involving the same variable up to degree three [e.g., (2x + 1) + (x2– 3x + 4)], using a variety of tools (e.g., algebra tiles, computer algebra systems, paper and pencil); There are four sets of cards (each group would get a set so they aren't all working on the same questions). Each set of cards will have answers that have the same characteristics (Set 1 - answer is a trinomial, Set 2 - answer is a binomial with no squared term, Set 3 answer is a binomial with no x term, Set 4 - answer is a binomial with no constant term). A set should contain 12 cards. Four long expressions, four algebraic answers and four algebra tile answers. Print and cut out the cards (we suggest laminating them to). Note that each card has what set number it belongs to so that if you mix them up you can easily sort them back into their sets. You may wish to put each set in an envelope or ziplock bag for easy distribution. You will probably want to have physical algebra tiles for students to use while doing the actual simplification. Note that because there doesn't seem to be a consensus on which colour algebra tiles represent positive or negative, there are two sets. One that assumes red is positive and one that assumes red is negative. Keep which ever is the protocol for your class and discard the other. Students could be put into groups or do this individually. Ether way, since there are only four sets you will need to have multiple copies of each set. Give each group an envelop and tiles and ask them to match the unsimplified expression with the simplified expression and algebra tile representation. Once each group is done, have groups switch their envelopes. (1 gives to 2, 2 gives to 3 etc). You can do this 4 times. SimplifyingPolynomialsMatching (pdf, doc) Did you use this activity?
