They had to be able to identify the number of angles, edges, vertices, and faces of each shape. Today I showed them how to create a program that would identify the shape based on its features.  We started out, like most programmers do, by making a flowchart.  I thought about using <a href=\"https:\/\/www.gliffy.com\">Gliffy<\/a> because there is no sign in required to create one (although you can&#8217;t save it), and it has the ability to type on the connectors, so we could have typed &#8220;yes&#8221; or &#8220;no&#8221; like <a href=\"http:\/\/www.gliffy.com\/go\/publish\/5915640\">this example<\/a>. However, I decided to go with <a href=\"http:\/\/popplet.com\/\">Popplet<\/a> since it was much easier to use and you can draw pictures in the shapes. Since we couldn&#8217;t write on the connectors like with Gliffy, we worked around it by making the shapes green for &#8220;yes&#8221; and red for &#8220;no&#8221;. Their flowchart was basically a decision tree for identifying the shape based on its faces (so it was limited to the cube, rectangular prism, and square pyramid). They created their flowchart, drew pictures of the 3-D shapes, and then took a screenshot. You can see a couple of student examples here: <a href=\"http:\/\/teachers.henrico.k12.va.us\/staffdev\/clough_d\/ITRTFiles\/45Spring2014\/3DShapes\/lauryn.png\">Lauryn<\/a> and <a href=\"http:\/\/teachers.henrico.k12.va.us\/staffdev\/clough_d\/ITRTFiles\/45Spring2014\/3DShapes\/mackenzie.png\">McKenzie<\/a>. Next I showed them how a spreadsheet and a formula can be used to identify the shape in a similar way. You can download the Numbers spreadsheet I used by clicking <a href=\"http:\/\/teachers.henrico.k12.va.us\/staffdev\/clough_d\/ITRTFiles\/45Spring2014\/3DShapes.zip\">here<\/a>. After looking at the example, I wanted them to write a simple formula on their own for distinguishing a cone and a cylinder.  They had to come up with one good &#8220;yes&#8221; or &#8220;no&#8221; question and then write the formula (which was something like this: &#8220;IF ANSWER=&#8221;YES&#8221; THEN &#8220;CONE,&#8221; IF NOT, THEN &#8220;CYLINDER&#8221;). There is a sample included with the template, if you download it, so you can see how it works. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Third graders in Ms. Leo&#8217;s class at Varina Elementary have been learning about solid shapes (SOL3.14).
