Rational Expressions: A Time When I Directly Told

http://rationalexpressions.blogspot.com/2014/10/a-time-when-i-directly-told.html

Hey, guys, it's Michael Pershan's blog! Series: On Feedback and Revision. Thursday, October 23, 2014. A Time When I Directly Told. OK, that’s the preamble. The full lesson plan is here. At the bottom of the piece.). Anyway, a pair of kids were organizing the class’ data on “Places where we like to read.” This was the data set they were organizing:. In my room, in bed. Home, in bed. In the living room in my house. In my bed with the puppy. In my room, in bed. Home, in bed. In the living room in my house.

Rational Expressions: Maybe It's OK To Prove Obvious Things

Hey, guys, it's Michael Pershan's blog! Series: On Feedback and Revision. Thursday, January 15, 2015. Maybe It's OK To Prove Obvious Things. I was poking around one of my favorite textbooks. For higher math, and I came across a problem that I thought was obvious. I felt, in myself, a weird combination of reactions:. Of course this is true! I have no idea how to prove this.". What a funny pair of things to think! Felt satisfying also, like I had cracked a puzzle or made a connection. As Dan puts it. In su...

Hey, guys, it's Michael Pershan's blog! Series: On Feedback and Revision. Saturday, January 3, 2015. Proofs of the Pythagorean Theorem - What Am I Even Trying To Teach? My students have always struggled to make sense of any sort of proof of the Pythagorean Theorem. It's hard math, but this year I have been trying to push myself to get clearer about why. The hard things are hard. I started making some progress on this when I started asking myself a series of questions during my planning time. Figuring out...

Hey, guys, it's Michael Pershan's blog! Series: On Feedback and Revision. Wednesday, July 30, 2014. Planning for Personal Change. How do teachers change? I've been reading a lot. How do you learn to write good web activities? I always have a project that I'm working on. I try to pick projects that will be useful to me, but that will also force me to learn some new skills. I don't try to just read about programming. I write down some questions that I have. When I'm stuck, I search broadly for ideas. But I...

Essay on Cognitive Load Theory. My First Blog (2010-2015). 8 “We’re taking it away from one side and putting it on the other.”. August 14, 2015. In the video above, the student describes adding 4 to both sides as “taking the 4 away from one side and putting it on the other.” This is difference then “balance reasoning” or using the subtraction property of equations. Where does this “Give and Take” model come from? The “give and take” model is a way of seeing equation-moves. It helps make s...Maybe not&#46...

Opposite of a Negative: Grades FAQ

http://joyceh1.blogspot.com/p/grades.html

Opposite of a Negative. Lesson plans, reflections, student work, and more. How tall is Mr. Joyce? This blog post is directed at a wide audience: my students, their parents, and teachers. To my students: I hope this provides a clear picture of how you can succeed in my class, as far as assessments are concerned. I realized from conferences that some students didn't truly understand the system 2/3 of the way into the year. To math teachers: I'd love any input on my system, suggestions, anything at all....

Suppose you’re working on adding multiples of 10 with your 3rd Graders. (Suppose, further, that you should be planning that lesson instead of writing a blog post. This will only take a second though, I swear! Here’s the thought. A lot of kids have trouble with 67 40 but can handle it without trouble if you encourage them to add a bunch of 10s.

Using Flubaroo to Update Students on Their SBG Progress | The Problem Bank

Math, PrBL, and SBG. October 26, 2012 / Jeff d. Using Flubaroo to Update Students on Their SBG Progress. So I can’t directly use the gradebook for this. (For example, even though I label all of my assignments according to the concept, I still have to score them on a 10 point scale). Anyway, here is what it can look like with Flubaroo. Open the spreadsheet. It’ll look like this:. You can add more standards to the right of this column and repeat. When you’re done, have Flubaroo grade it. The e-mail looks l...

Trying to figure out how to blog and teach math at the same time. Author Archives: Sam Olderbak. December 24, 2016. I hate everything about homework (I guess except for the idea of it). I hate trying to figure out what is the best way to grade homework. Do you grade for participation or correctness? Maybe I should just give quality feedback instead. That will motivate students to put in more effort, right? I am sure it would, but who has time for that? How many problems do I assign? Except for the fact t...

Estimations and Wagers | Informal Math

https://informalmath.wordpress.com/2015/07/02/estimations-and-wagers

Trying to figure out how to blog and teach math at the same time. July 2, 2015. So I create a game and it is a total rip off of Wits and Wagers. The basic idea is the students are given some sort of situation to estimate. They each right their estimation on their card. Students place the cards in order from least to greatest. They wager on which answer they think is correct. Then they check their answer. This entry was posted in Uncategorized. MTFSO–Graphing Polynomials →. July 13, 2015 at 1:30 am. You a...

Connecting Research and Practice in Education. Why I love lesson study. I love lesson study. I recently finished another cycle and I was thinking back to when I first learned about it. I remember talking with Sadie. About my frustration of doing workshops and having some teachers say, “That sounds great and all, but I can’t do that with my kids.” Sadie pushed me to use lesson study as a way to help teachers see what their kids CAN do. Here’s the main reason I love lesson study:. I also love it because it...

Rational Expressions

Algebraic fractions are quotients of algebraic expression. If the expressions are polynomials, the fraction is called rational expression. It can be written in the form of $ frac{P}{Q}$, Q$ neq0$ and P, Q both are polynomials. Simplify $ frac{125a {2}b {3} {10a {3}b}$. First factorized, 125a. Frac{125a {2}b {3} {10a {3}b {1} $ = $ frac{5 * 5 * 5 * a * a * b * b * b} {2 * 5 * a * a * a * b}$. Cancelling the common terms. Frac{125a {2}b {3} {10a {3}b {1} $=$ frac{25b {2} {2a {2} $.
