This 4-5 week Common Core-aligned Mathematics unit is designed to introduce students to the operations of addition and subtraction, and to provide students the opportunity to apply these operations. Throughout the unit, students will model by counting all or taking away, and counting on. Guided practice with these methods will lead to growth in Grade 1 and fluency and precision in Grade 2. This task includes the recall of facts in one-step operation problems within twenty and requires students to make some decisions on how to approach the problem using basic addition and subtraction skills. It demands reasoning abilities, and students must apply their understanding of operations to solve a problem presented in a novel and unrehearsed way.
