This is in a PDF file because its the only way to put it in one file. The activity is huge, it has 3 levels of difficulty, green being the easiest (showing on a number line) and red being the hardest (solving including squares).
Because some of the yellow ones have been scanned back in it means some of the triangles are slightly smaller than others. This doesn't cause a problem when doing the jigsaw. Or it hasn&'t for my kids.
Something went wrong, please try again later.
Thank you
This was an awesome puzzle as it came in layers - students could get a sense of completion and feel challenged to take on the next tier! Thanks! Since you have the original, perhaps you could fix one small error. For it to work, you have (in yellow) 4(3x+2)>=38, matching x>=3 1/6. The solution should be x>=2.5. However, there is another 2.5, so that made it confusing.
Genius idea.
