This poster goes well with the set Sarah created about <a href=\"https:\/\/mathequalslove.blogspot.com\/2018\/07\/solutions-roots-zeros-and-x-intercepts.html\">solutions, roots, zeros and x-intercepts<\/a>; that&#8217;s how she&#8217;s got them in her room, after all!<\/p>\n<p>Now, the poster doesn&#8217;t capture all the particulars of these algebraic tools; it&#8217;s just a simple poster showing one example. There were some comments on twitter about the fact this poster doesn&#8217;t completely define what a function is, particularly absent a discussion of sets. Also, there was concern that the equation example implies all equations are homogeneous. Both criticisms have an element of truth, but also miss the point of a poster that, by its nature, only has one example. I think posters serve the best as either reminders of topics already discussed or starting points to launch a deeper discussion or investigation. Please, never put a poster on a wall and assume that means you&#8217;ve taught a topic. For an example of how I&#8217;ve discussed functions before, <a href=\"https:\/\/www.primefactorisation.com\/blog\/2017\/09\/11\/functions-inb-page\/\">see these notes that I used in Algebra 2 last year<\/a>.<\/p>\n<p><a href=\"https:\/\/www.dropbox.com\/sh\/frm4ve62703ksi3\/AADhnqjwbIeUnlkNt3fFCyoBa?dl=0\">Downloads are here.<\/a><\/p>\n<p>This one may be a little tricky to put together, so if you want some guidance, keep reading:<\/p>\n<ol>\n<li>Choose your three colors. The effect works best (and helps communicate the idea) if the middle color appears to be a blend of the other two. If you don&#8217;t want to think too hard, just use blue-green-yellow like me, but I&#8217;d love to see other color combinations too.<\/li>\n<li>Print the first page (function) on the first color (blue, in my case), and the second page (equation) on the last color (yellow).<\/li>\n<li>Print <em>either<\/em> page on the middle color (green). For this page, you only need the expression rectangle, which appears on both pages. Cut off the rest of the paper.<\/li>\n<li>Stack your three pages with the expression rectangle of each page overlapping, with the middle color on top. Make sure you line up the rectangles as perfectly as you can.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>The other day, Sarah showed me this tweet, and told me she wanted to make a poster based on it: Wonders of the algebraic language cc @cgironella2005 @mathequalslove pic.twitter.com\/Bp8HfmqhDg \u2014 yair.es (@notemates) August 6, 2018 She wasn&#8217;t sure how she would do it.
