Hi everyone, I have an idea and I'm not sure whether or not it would work: Those of us who have been teaching a while have certain favorite worksheets. They're the ones we go to, year after year. They either explain a concept well, push the kids to learn more or better, or just excite the class. Why not share with our friends? I've been out of the classroom a while, so I would have to dig through my files. But I can think of 3 right off the top of my head (All High School, sorry): Geometry: "Arcs and Angles Monster". It's a huge circle with something like 26 pieces to fill in. Here's how I use it: I tell the kids it's a group test. They can work alone or together, but by tomorrow's class we'll decide by consensus what their answers will be. They can use any resources available: textbook or notebook, but if they know the formulas, nothing else is needed. Then they get to work. When the next class starts, I ask "Angle 1?" and they quickly decide on an answer. And so on down the answer sheet. They tend to get most of the answers right. Everyone in the class gets the same grade; they enjoy the break from a normal class and they tend to learn the formulas. It's not something I could ever hope to put on the computer-- my skills at diagrams are abysmal-- but I would be happy to mail it to anyone interested. Algebra II/Trig: I have a good sheet on Composition of Functions. It's basically 6 or 8 functions, set up on a grid. You have to do (A(Bx)), B(C(x)) and so on, and each of the answers is one of the original problems. I could easily type it and email it if you're interested. Pre-calc: Intro to Matrix row reduction: When you first teach kids to use matrices to solve a system of equations, they have a hard time just following the algebra. So I always start with this sheet. It's a series of 4 problems, all worked out, with the directions getting them from step to step. Once they get the hang of how to follow the directions, they have a much easier time coming up with the actual steps themselves. On computer; I could email it to you anytime. I'm sure I have more. Anyone else interested in sharing? Please specify both the topic and suggested grade, since each state has its own standards and things may not jive exactly. Thanks!

This is a wonderful idea. I would love to dig around sometime and share some from 4th grade and am defiinitely in need of some 7th grade math ones. In 4 years of teaching I've had 4 different traching assignments so I don't have the luxery of favorites yet since every year has required recreating a whole new set of lessons. I did create a few standardized test-formatted exams to compensate for the Scott Foresman reading text lack of higher order questions. I did that for a few stories and have my (terrible) Spanish translation copy as well. I have a Mr. Potato Head graphic organizer that I drew up for character analysis somewhere as well.

I would like to join in, but most of my materials are at school and I will not be able to get back in the bldg. for several weeks. I teach fourth grade.

I'll have to dig one out, retype another, and mail a third. If anyone is interested in secondary math, maybe PM is the way to go until I get to it?

Here's what I have on my home computer that might be of interest: Lit circle or end-of-book questions for: Freak the Mighty, Island, Frindle, Shiloh, Secret School Pre-algebra final exam Instructions for a book project where you make an original game

If you can email it, I should think you can attach it, or even post it here. Alice, I would ADORE having your Arcs and Angles, Composition of Functions, and Matrix sheets. (Don't I keep telling you I wanna be in your class??)

I should also mention: NY state gives comprehensive exams in a lot of High School subjects, known locally as "Regents Exams". They're a GREAT resource for test questions. Here's the website: http://www.nysl.nysed.gov/regentsexams.htm

Remember how I said my greatest weakness was anything having to do with technology?? I wasn't kidding! I can't figure out how to attach the matrix worksheet, so here it is: Ideally it should be in 2 columns, so the entire sheet fits on one piece of paper. USING MATRICES TO SOLVE A SYSTEM OF EQUATIONS ** “A”,”B” &”C” refer to the first, second and third lines respectively of the PRECEDING matrix. What is A in one step might easily be C in the next.

Could you PM me a little more about this one? I'm elementary, but I think I can modify it for my class.....Thanks!!

I'm not sure it apply to elementary kids, but here's what's involved: It's a huge circle with 2 secants and 2 tangents (I think) drawn to it. There are a few chords and radii within. You're given enough info to use the formulas for: Central Angle Inscribed Angle Angle formed by 2 chords Angle formed by tangent and chord Angle formed by 2 tangents Angle formed by 2 secants -- all in terms of the intercepted arc(s) Still interested? Let me know.

I'll post them once I get a chance. I need to reinstall word onto my new computer before I can access mine.

Oops, sorry! My math is good; my typing skills aren't anything to brag about! When I give the sheets to the kids, that first example is blank. I talk them through it.
