How much do they already know? What areas need more work?<\/p>\n<p>Once you&#8217;ve assessed their level of understanding, it&#8217;s time to get creative.<\/p>\n<h3>Give these Pythagorean Theorem themed activities a go!<\/h3>\n<\/div><div class=\"fusion-text fusion-text-2\"><h3><b>1. Find the missing length<\/b><\/h3>\n<p>For younger students, create a giant triangle on poster paper in front of your class and write unknown side lengths on each corner.<\/p>\n<p>Have students measure each side using rulers or measuring tape and then calculate the remaining sides using the theorem. This activity can be made more interactive by having students guess the answers before they measure them.<\/p>\n<p>Think out of the box! Use fun visuals such as diagrams, images and videos to make the learning more engaging.<\/p>\n<p>For example, here&#8217;s how you can <strong><a href=\"https:\/\/www.youtube.com\/watch?v=jG6XVCgdGLA\" target=\"_blank\" rel=\"noopener\">teach Pythagorean Theorem\u2026 using chocolate! <\/a><\/strong><\/p>\n<div class=\"video-shortcode\"><iframe title=\"Real World Mathematics: Chocolate Pythagoras\" width=\"1160\" height=\"653\" src=\"https:\/\/www.youtube.com\/embed\/jG6XVCgdGLA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div>\n<\/div><div class=\"fusion-clearfix\"><\/div><\/div><\/div><\/div><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-2 nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"background-color: rgba(255,255,255,0);background-position: center center;background-repeat: no-repeat;padding-top:0px;padding-right:0%;padding-bottom:0px;padding-left:0%;margin-bottom: 0px;margin-top: 0px;border-width: 0px 0px 0px 0px;border-color:#eae9e9;border-style:solid;\" ><div class=\"fusion-builder-row fusion-row\"><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-1 fusion_builder_column_1_1 1_1 fusion-one-full fusion-column-first fusion-column-last\" style=\"margin-top:0%;margin-bottom:0%;\"><div class=\"fusion-column-wrapper fusion-flex-column-wrapper-legacy\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;border-radius:22px 22px 22px 22px;background-color:#dbe3e9;border-width: 0 0 0 0;border-color:#eef2f5;border-style:solid;border-radius:22px 22px 22px 22px;overflow:hidden;padding: 40px 40px 40px 40px;\"><div class=\"fusion-builder-row fusion-builder-row-inner fusion-row\"><div class=\"fusion-layout-column fusion_builder_column_inner fusion-builder-nested-column-0 fusion_builder_column_inner_1_2 1_2 fusion-one-half fusion-column-first\" style=\"width:50%;width:calc(50% -
