Here&#8217;s something Robert did while &#8220;guest teaching&#8221; a\u00a05th grade class a few weeks back:<\/p>\n<div id=\"attachment_848\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-848\" loading=\"lazy\" class=\"size-medium wp-image-848\" src=\"http:\/\/bltm.com\/blog\/wp-content\/uploads\/2015\/12\/division-brain-fuck-300x254.jpg\" alt=\"division brain teaser\" width=\"300\" height=\"254\" \/><p id=\"caption-attachment-848\" class=\"wp-caption-text\">One way to wake up a boring division lesson&#8230;.<\/p><\/div>\n<p>As they say, &#8220;you wouldn&#8217;t believe what happened next!&#8221; A few\u00a0impulsive students (all boys, as usual) rolled their eyes and called out &#8220;35! 35!,&#8221; which is exactly what he wanted to happen. However, among all these students who had only a superficial understanding of division, one girl shook her head. &#8220;It&#8217;s a stupid question!&#8221; she explained, &#8220;any of those numbers can be a dividend. You could write 7 \u00f7 35, 5 \u00f7 7, and\u00a035\u00a0\u00f7 5. The size of the numbers means nothing, so any of the three could be a dividend!&#8221;<\/p>\n<p>All of which led into a very interesting about what the &#8220;function&#8221; of a dividend is, which led to even more insights into the relationship between divisors and quotients.<\/p>\n<p>Later in the day, Robert bumped into &#8220;K&#8221; getting lunch. &#8220;So, how did it go?&#8221; he inquired. &#8220;Oh, it wasn&#8217;t the worst thing I ever did&#8230;.&#8221; she replied.<\/p>\n<p><i>Wise educators who liked the post above, also put this in their shopping cart:<\/i><\/p>\n<div id=\"attachment_851\" style=\"width: 241px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.teacherspayteachers.com\/Product\/Long-Division-and-Division-Take-My-Word-For-It-Youre-Teaching-It-Wrong-1372015\" target=\"_blank\"><img aria-describedby=\"caption-attachment-851\" loading=\"lazy\" class=\"wp-image-851 size-medium\" src=\"http:\/\/bltm.com\/blog\/wp-content\/uploads\/2015\/12\/original-1372015-1-231x300.jpg\" alt=\"Division: You're Teaching It Wrong!\" width=\"231\" height=\"300\" \/><\/a><p id=\"caption-attachment-851\" class=\"wp-caption-text\">Read this and learn 12 more ways to get division right in your classroom!<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Robert\u00a0stops in to see K, the\u00a0sixth grade teacher, who is twelve kinds of awesome and always quick with a witty phrase (it was from her where I learned to say &#8220;for all shits and giggles&#8230;.&#8221;) K looks tense.
