\u201cBecause almost all the rest use a plus but that one uses a minus; that’s the only one that uses the minus.\u201d <\/p>\n\n\n\n
1st grade Mathematicians played \u201cWhich One Doesn\u2019t Belong\u201d this week, warming up their noticing and terminology about equations and expressions as they compared and contrasted four related examples. After the warm-up, students looked at a math story picture, showing a scene with multiple children and adults, some standing, some sitting at tables, some using pattern blocks, some using markers or pens, some watching. The activity challenged students to look closely and generate a math question that peers could describe with an equation and solve using the picture. <\/p>\n\n\n\n
\nThere are 6 kids making shapes and two teachers watching, how many people are there all together?<\/p>\n<\/blockquote>\n\n\n\n
Students wrote a wide range of math questions, like \u201cThere are six kids making shapes and two teachers watching, how many people are there all together?\u201d And, \u201cIf we split the two tables, how many people are at each table?\u201d Students presented their question, covering up their solution and equation, under the document camera for all to see. They called on peers to offer an equation to match, and their teacher supported them to find as many possible equations that worked. After sharing equations and a solution, students discussed where to \u201cput the box,\u201d which is used in 1st Grade to highlight the unknown value or values. If there are 10 markers and 9 pencils, how many are all together? \u201c10+9=19\u201d is one way to show this. Where would the box go? As one student explained, \u201c[Around] the 19 because that isn\u2019t what he wrote.\u201d <\/p>\n\n\n\n
In one question, students realized there were two unknown values and more than one possible solution based on how the solver understood the \u201csplit tables” idea. Whichever flexible, small group students learn math in, these community warm-ups and discussions stretch their math flexibility, communication, and ability to understand others\u2019 reasoning, and prepare them to solve word problems that vary in the position of unknown value and that have either one or many possible solutions.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
