“Visual” math & devEd

From my tweetworld:  I think this is an excellent idea:   present these potentially overwhelming streams of symbols in a way that helps the learner know what to look at.   (I also think we need to include practice reading stuff without that little crutch.) That said, it’s just a better-looking presentation of … symbols.   It doesn’t […]

Geogebra.   “Lists” are a lot like arrays, tho’ the first element is list(1) not zero; zero will get “undefined. No, I still have no idea how to actually SET THE STUPID X AXIS TO THE SIZE I WANT.   I mean, I know how to set it but it changes if I so much as move […]

So… exponents and variables and … zero power.   It’s a “touch base on this” section in pre-Algebra, nothing huge or convoluted (and I don’t *think* negative powers). It just might stick.   Things squared?  Write it out as this times itself until you don’t have to.   Zero power?  write it out as base/base […]

Well, yesterday I *did* successfully put together “1.4”  — adding integers with the same sign number on the number line.   Next weeK  :   1.5   (adding different signs, then mixing htem up.) THen for *my* course I”m going to follow the ORton-Gillingham principle of ‘don’t teach the […]

  Whereas, I searched around for nice posters, visuals, etc.  about subtracting with borrowing.   5 minus a fourth. I found lots of examples of varying degrees of appeal. All of them were all numbers and symbols.   None of them did that “concrete to abstract” transition.   In my experience (the phrase I put […]

Lots of folks think that algebra and math NEED TO BE RELEVANT for students to be motivated to learn it, and all kinds of efforts are made to develop “real world” things to solve. While I think this is a worthwhile path, I appreciated somebody (if I can remember who, I’ll edit) who broadened “relevant” […]
