Well, some of the practice activities are well done so I thought I’d check ’em out for my OER lesson for Adult Ed.
Negative integers — the intro movie is not bad… but … you get the first exercise right and … you’re done. you get the points. And, by the way? The first exercise in “putting negative numbers on the number line” has you put … a positive number on the number line.
But you are ready to move on to the next thing, really!
So I get the next one (also positive) wrong. I get my chance now to get five in a row practicing — the first four of which are .. positive. Get that fifth and “points time!” and I’m done. So I’ve successfully answered, again, a single practice problem putting numbers on the number line and … time to move on!
I will include it in my resources but yea, it’s not the stuff of actually learning unless you “get it” with one practice.
I liked the next stage: students plot missing numbers on the number line, adn we’ve got a 10 and a mark and a 16, so they’ve got to figure out the spacing, etc. I like it for the conceptual aspect, tho’ w/ my target audience we’d start that stuff with the more familiar positives.
