It involves VNPS. This stands for &#8220;Vertical Non-Permanent Surface&#8221; and the goal is to get students up on their feet working working on a surface that easily erases, which means they don\u2019t have to be afraid to make mistakes (see image below). I&#8217;ve had students do VNPS individually sometimes and in groups other times. When I use groups I have the students draw cards to determine their partners. I do this based on the recommendations of <a href=\"http:\/\/www.peterliljedahl.com\/\">Peter Liljedahl<\/a> in order to ensure fairness, that students work with others they wouldn&#8217;t normally choose to work with, and mainly to avoid the constant complaints \ud83d\ude42<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-307\" src=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8627-1024x768.jpg\" alt=\"\" width=\"640\" height=\"480\" srcset=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8627-1024x768.jpg 1024w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8627-300x225.jpg 300w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8627-768x576.jpg 768w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<p>VNPS is nothing new. Many math teachers all over the world are using it in their classrooms. <strong>So how have I been using it specifically?<\/strong> <span style=\"color: #0000ff;\"><em>(FINALLY THIS GUY GETS TO THE POINT! So much for short and sweet!)<\/em><\/span> I&#8217;ve been giving my students the skeleton of problem and then I have them choose their own values for the constants and exponents I&#8217;ve indicated. The image below is an example of this.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-310 size-large\" src=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8625a-1024x731.jpg\" alt=\"\" width=\"640\" height=\"457\" srcset=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8625a-1024x731.jpg 1024w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8625a-300x214.jpg 300w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8625a-768x548.jpg 768w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<p>This way each student\/group has their own unique problem, whose answer will most likely not be &#8220;nice&#8221;. Interestingly enough, the feedback from my students has been that they like having to work through problems with &#8220;not nice&#8221; answers, unlike the problems in their textbooks.<\/p>\n<p><strong>So how do I check their answers?<\/strong> I&#8217;m so glad you asked. <a href=\"https:\/\/www.desmos.com\/calculator\">Desmos<\/a> of course! I type in the equation I gave the students with the constants <em>a<\/em>, <em>b<\/em>, <em>c<\/em>, etc. and Desmos allows me to create sliders for these constants (careful not to use certain letters that already have pre-programmed values like <em>e<\/em> and <em>i<\/em>). When a student wants their answer checked, I simply input their <em>a<\/em>, <em>b<\/em>, <em>c<\/em>, etc. values and Desmos tells me the answer immediately (see image below). <a href=\"https:\/\/www.desmos.com\/calculator\/2uvpplxjon\">Here is the Desmos graph I used<\/a> if you&#8217;d like to play with the sliders.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-304 size-large\" src=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/Desmos-1024x468.jpg\" alt=\"\" width=\"640\" height=\"293\" srcset=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/Desmos-1024x468.jpg 1024w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/Desmos-300x137.jpg 300w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/Desmos-768x351.jpg 768w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/Desmos.jpg 1920w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<p>Here are a few shots of what my students came up with.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-306 size-large\" src=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8626-1024x768.jpg\" alt=\"\" width=\"640\" height=\"480\" srcset=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8626-1024x768.jpg 1024w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8626-300x225.jpg 300w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8626-768x576.jpg 768w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-308 size-large\" src=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8628-1024x768.jpg\" alt=\"\" width=\"640\" height=\"480\" srcset=\"https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8628-1024x768.jpg 1024w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8628-300x225.jpg 300w, https:\/\/cohort21.com\/michaelmoore\/files\/2019\/11\/IMG_8628-768x576.jpg 768w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Another example of when I used this was during a product rule lesson.

Off the top of my head&#8230;<\/p>\n<ul>\n<li><strong>Grade 9<\/strong> &#8211; Have students choose 2 random points and determine the equation of the line passing through them. Set up Desmos to calculate the slope and <em>y<\/em>-intercept automatically.<\/li>\n<li><strong>Grade 10\/11<\/strong> &#8211; Have each student solve their own intersection of a parabola and a line problem. They choose their own <em>a<\/em>, <em>b<\/em>, <em>c<\/em> values for a quadratic in standard form and the slope and <em>y<\/em>-intercept of the line, then solve the system. Have Desmos graph the two functions and then click on the POI&#8217;s. (You could also start the quadratic in factored or vertex form to add a challenge. Now that I think about it, this is probably better because it&#8217;ll be easier to ensure that the system has solutions.)<\/li>\n<li><strong>Grade 12 Advanced Functions<\/strong> &#8211; Set up a general polynomial in factored form, with some factors having powers or 2 or 3, then have them choose their zeros and sketch their unique graph. Have Desmos graph their function and compare.<\/li>\n<\/ul>\n<p>Ok, I think I&#8217;ll stop my rambling here.
