Rounding can be used when an <i>exact<\/i> number isn&#8217;t needed, and an approximate answer will do. \u00a0In real life, rounding and estimation are part of our everyday experiences.\u00a0 When you\u2019re shopping in the grocery store and trying to stay within a budget, for example, you estimate the cost of the items you put in your cart to keep a running total in your head.\u00a0 When you\u2019re purchasing tickets for a group of people or splitting the cost of dinner between 8 friends, we estimate. \u00a0If students can apply this skill to these type of everyday experiences, we know they have not just learned the skill, but understand the concept.<\/p>\n<p>For students, estimating is an important skill.\u00a0 First and foremost, we want students to be able to determine the reasonableness of their answer.\u00a0 Without estimation skills, students aren\u2019t able to determine if their answer is within a reasonable range. \u00a0Second, we want students to be able to use mental math to more quickly arrive at\u00a0 a reasonable solution.\u00a0If students\u00a0don\u2019t understand the number sense behind rounding, no matter what number they underline or look at, it won\u2019t be solid conceptual understanding.<\/p>\n<figure id=\"attachment_2979\" aria-describedby=\"caption-attachment-2979\" style=\"width: 439px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\" wp-image-2979\" src=\"http:\/\/www.thesummitprep.org\/2nd\/wp-content\/uploads\/sites\/5\/2017\/02\/IMG_0032-1-300x225.jpg\" alt=\"I Have, Who Has? is one of our favorite activities to practice the skills we are learning!\" width=\"439\" height=\"329\" srcset=\"https:\/\/www.thesummitprep.org\/2nd\/wp-content\/uploads\/sites\/5\/sites\/5\/2017\/02\/IMG_0032-1-300x225.jpg 300w, https:\/\/www.thesummitprep.org\/2nd\/wp-content\/uploads\/sites\/5\/sites\/5\/2017\/02\/IMG_0032-1-150x113.jpg 150w, https:\/\/www.thesummitprep.org\/2nd\/wp-content\/uploads\/sites\/5\/sites\/5\/2017\/02\/IMG_0032-1-768x576.jpg 768w, https:\/\/www.thesummitprep.org\/2nd\/wp-content\/uploads\/sites\/5\/sites\/5\/2017\/02\/IMG_0032-1-1024x768.jpg 1024w\" sizes=\"(max-width: 439px) 100vw, 439px\" \/><figcaption id=\"caption-attachment-2979\" class=\"wp-caption-text\">I Have, Who Has? is one of our favorite activities to practice the skills we are learning!<\/figcaption><\/figure>\n<figure id=\"attachment_2980\" aria-describedby=\"caption-attachment-2980\" style=\"width: 395px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\" wp-image-2980\" src=\"http:\/\/www.thesummitprep.org\/2nd\/wp-content\/uploads\/sites\/5\/2017\/02\/IMG_0033-1-225x300.jpg\" alt=\"We rolled 3, 4, and 5 dice to create numbers up to 10,000.
