Has any one found any websites you feel will be helpful beefing up Alg I or Alg II classes? I have several texts at my disposal to find problems and story problems. But I am looking for ideas to have students find data or do research to apply to problems. I'm afraid I'm not too creative when it comes to making my own problems.

How can I-Pads be used as an effective way for students to practice their math skills? Are there any free apps that students can use to practice math skills?
OK, so doing practice on worksheets is bad, but doing practice on Ipads is good.
As the Jaime Escalante character says near the end of the movie when he is informed the school is finally going to get the computers that he was originally hired to teach: "Yep, that'll do it.
But look at how much money we save by replacing a 2 cent piece of paper with an $800 piece of Apple profits. AND create a classroom management problem.
Making Equivalent Fractions- 4.NF...See MoreI am new to teaching Math this year, and I am wondering just how to go about teaching it more effectively. What I would like to see is examples of sketched out weekly lesson plans. For example, for fractions, I would like to see how others teach each standard in each domain how many days for each standard.
Making Equivalent Fractions- 4.NF.1
Comparing Mixed Fractions - 4.NF.2
Sums and Differences of Like Fractions- 4.NF.3
Add and Subtract Mixed Numbers With Like Denominators- 4.NF.3
Sum and Difference Fraction Word Problems - 4.NF.3
Fractions and Whole Numbers in Words and Visuals- 4.NF.4
Fractions and Whole Number Multiplication- 4.NF.4
Products of Fractions and Whole Numbers in Word Problems- 4.NF.4
Denominators of Tenths and Hundredths- 4.NF.5
Decimal Notation for Fractions (10 or 100 Denominators)- 4.NF.6
Compare Two Decimals (to the hundredths place)- 4.NF.7
We have 15 days for equivalent fractions, but we haven't been told what we should do beyond the first 3 weeks of this quarter.
Is it possible that Camtasia could be integrated into a middle or high school math class? Even if only as something for a substitute teacher to play if I am unable to teach? Would it be useful as an online reference for students?
I know that I may be asking for magic, but there must some tricks out there. I'm speaking specifically about Pre Alg and Algebra 1.
I have students who understand integers, understand what they need to do, but will still multiply when addition is called for, multiply a neg x neg in one part of the problem correctly and then, in the same problem, do it incorrectly?
Are there any suggestions by experienced teachers?
That's when I ask them, Are you trying to get it right, or trying to get it done? 8th and 9th graders are much more interested in getting the paper turned in, right or wrong, than they are in patiently working through a problem properly. Their minds are on what they are doing, they are in auto-drive.
I've thought of giving them ONE problem, making each step, including the check stage worth however many points.
A terrific collection of MANY Foot Theme lessons, activities, interdisciplinary for prek-3 planned around Animal Tracks and other foot related topics. Math, science, literacy.
Does anyone know where logic c...See MoreI have been working on my web site to provide teachers a definitive free resource for the core curriculum for a while now. Many teachers are asking me to create Logic worksheets. I align all of my sheets to the Core Math Curriculum, to make it easier for teachers. I see no logic skills any where in the core.
Does anyone know where logic comes into play in the Core Curriculum. I can't believe that they would totally abandon logic as a skill.
Definition of a^(1/n) is the answer ------------------------------------ x=a^(1/n) is called as principle n^th real root of a and such root when it exists, is by definition either a positive number or zero, eg. 4^(1/2). When n is odd, the principle n^th real root may be a +ve or -ve number and it needs no special consideration since it can be easily found. eg. (-8)^(1/3) or (8)^(1/3).
Why consider only positive roots?
If x=8 then squaring operation such as x^2=64 introduces -8 as an extraneous root-meaning you start with x=8 to get x^2 = 64 but to get x back from x^=64 you get unintended x=-8. Thus, it is customary to consider only the principal n^th root in simplification of terms such as (16)^(1/4)=+2, (64)^(1/2)=+8 and exclude -2 and -8. Addressing the root in context as extraneous (and sometimes redundant, spurious or vacuous) seems appropriate since to derive x^2=64 from given x, x=8 is sufficient. Considering x=-8 does not generate any additional information in getting x^2=64 by the squaring operation.
Best regards.

Here is application of above explanation to your original question 16^(3/4)=+8. Why not -8 too?
16^(3/4) = ((16)^(1/4))^3 =(+2)^3 (By definition 16^(1/4)=+2 explained in my previous post) =+8
Best regards.
