This week, second grade mathematicians kicked off Unit 6: Whole-Number Operations and Number Stories. The unit will strengthen students’ ability to use diagrams to solve number stories, as well as help them learn strategies, such as partial-sums model, for multidigit addition. Later in the unit, students will develop an understanding of multiplication and division by using manipulatives and drawing arrays. Second grade mathematicians also had a special challenge during Thursday’s Problem Solving Investigation lesson. They reviewed the five problem solving strategies they have learned so far this year and had a choice of strategies from which to solve this week’s problem. Math Stations folders continue to offer enrichment, differentiation, and choice to students as they finish their math classwork. Lastly, second grade math superstars are excited to celebrate the 100th Day of School next week!
