One was simply having students choose a number and then create an equation for that number. To make it slightly more challenging at the Intermediate and Advanced levels, I had the Intermediate level focus on <strong>even<\/strong> and <strong>odd<\/strong> numbers and the Advanced level focus on <strong>fractions<\/strong> and <strong>mixed numbers<\/strong>.<\/p>\n\n\n\n<p>My second goal was to have students think about the placement of their number when they were placing it on the clothesline. I intentionally only allowed the Beginning Level to use the numbers 1-20. These little guys are still learning about numbers on a number line and I didn&#8217;t want to confuse their learning by having a fifth grader add a number like 2 1\/4 in between the numbers 2 and 3.<\/p>\n\n\n\n<p>I knew even before I did the activity that there would probably be a lot of shifting numbers once students started hanging their numbers. For example, if the numbers 45 and 46 were hanging next to each other and a student needed to add the number 45 1\/2, it would be necessary to slide the numbers apart to make room for it. But that&#8217;s great and part of the learning.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"338\" src=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-450x338.jpeg\" alt=\"\" class=\"wp-image-5717 size-full\" srcset=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-450x338.jpeg 450w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-300x225.jpeg 300w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-768x576.jpeg 768w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-1536x1152.jpeg 1536w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-2048x1536.jpeg 2048w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline29-360x270.jpeg 360w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p><strong>Multiple Representations<\/strong><\/p>\n\n\n\n<p>Another goal was to have students see that numbers can be composed in different ways. To do this, I needed to figure out how to hang the repeat numbers to maintain an accurate number line. That&#8217;s when my assistant came to the rescue with the idea to use tape and hang repeat numbers off of each other vertically.<\/p>\n<\/div><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading has-text-align-center\"><strong>What I Learned and useful Tips<\/strong><\/h1>\n\n\n\n<p>Over the many years of hosting Family Math Night events, I&#8217;ve learned that anytime there are colorful pens and scissors on the table, it&#8217;s going to be a busy station. And that&#8217;s exactly how this station unfolded. The sixth grade station facilitator in charge of this station was kept on her toes all evening.\ufeff<\/p>\n\n\n\n<p>One thing I did notice was the young kinders weren&#8217;t sure where to place their number on the clothesline. So next time I&#8217;m going to add a large 1-20 number path somewhere on the wall next to the left-hand side of the clothesline as a support tool in case the younger students need help placing their numbers.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"338\" src=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-450x338.jpeg\" alt=\"\" class=\"wp-image-5718 size-full\" srcset=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-450x338.jpeg 450w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-300x225.jpeg 300w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-768x576.jpeg 768w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-1536x1152.jpeg 1536w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-2048x1536.jpeg 2048w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/IMG_1352-360x270.jpeg 360w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"has-text-align-center has-medium-font-size\"><strong>Tip #1<\/strong><\/p>\n\n\n\n<p>So that families have a general idea of what&#8217;s going on with the clothesline, it&#8217;s a good idea to &#8220;seed&#8221; it with a few numbers. We used the numbers 5, 11 and 56 on our clothesline and placed them in the appropriate linear spot on the line. That gave students a starting point when figuring out where their number went.<\/p>\n<\/div><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"452\" src=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a-450x452.jpeg\" alt=\"\" class=\"wp-image-5720 size-full\" srcset=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a-450x452.jpeg 450w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a-300x300.jpeg 300w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a-150x150.jpeg 150w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a-768x771.jpeg 768w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a-269x270.jpeg 269w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline2a.jpeg 1512w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"has-text-align-center has-medium-font-size\"><strong>Tip #2<\/strong><\/p>\n\n\n\n<p>Since it&#8217;s a clothesline, I thought it would be fun to add actual clothespins. I found some colorful ones on Amazon. The key here is to make sure participants hang their number &#8220;tent&#8221; on the clothesline BEFORE they add the clothespin. Hanging the tent first then adding the clothespin helps ensure that the number hangs correctly.<\/p>\n<\/div><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"455\" src=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-450x455.jpeg\" alt=\"\" class=\"wp-image-5722 size-full\" srcset=\"https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-450x455.jpeg 450w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-297x300.jpeg 297w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-768x776.jpeg 768w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-1520x1536.jpeg 1520w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-2027x2048.jpeg 2027w, https:\/\/www.familymathnight.com\/blog\/wp-content\/uploads\/2026\/10\/clothesline22a-267x270.jpeg 267w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"has-text-align-center has-medium-font-size\"><strong>Tip #3<\/strong><\/p>\n\n\n\n<p>Sometimes a child works sooo hard on their project that they completely fall in love with it and don\u2019t want to let it go.
