2. Special thanks to the second grade members of the Mathematics Leadership Team: Amanda Butcher, Dawne Wornick and, Billie Faircloth who worked so hard to make these problems possible. Each “Problem of the Day” is correlated to our Cumberland County Task Analysis for the purpose of practicing each objective through problem solving. Each problem will be either a performance task, short answer, or multiple choice which allows students to work with problems through many avenues. When using “Problem of the Day” provide students with manipulatives (which may include a calculator) and a mathematics journal. Expect each student to solve the problems and record his/her answer in a math journal. Students should include, along with the answer, a number sentence, a unit, a drawing (proof picture), and a written explanation of how the problem was solved. After students have time to solve the problem independently, students should discuss solution strategies with their team. Following team discussions, review the correct answer and the reason it is correct. In the case of multiple choice problems review why answers are incorrect.
