Write an equation to express the total of an array Assessments: Topic 2 Assessment Addition/Subtraction fluency quizzes Interdisciplinary Connections: Connecting arrays to real world situations (shelves in stores, parking lots, donuts in a box, windows in buildings, etc). Additional Resources: (Math games) Pearson, enVisionmath2.0 Subject: Mathematics Grade: 2 Suggested Timeline: 9 days Topic 3: Add Within 100 Using Strategies Topic 3 Overview/Essential Understanding: Patterns on a hundred chart can be used to add numbers and to develop mental math strategies and number sense. Two-digit numbers can be broken apart into tens and ones and added in different ways. When adding two-digit numbers, you can add an amount to one addend and subtract the same amount from another addend to make addition easier. Some problems can be solved in one step, while others need to be solved in two steps. Good math thinkers know how to pick the tools to solve math problems. Topic 3 Objectives: At the end of Topic 3, students will be able to independently use their learning to: add within 100 place value strategies and a hundred chart add tens and ones to two-digit numbers using an open number line within 100 break apart numbers into tens and ones to find their sum
Apply properties of operations as strategies to add and subtract Technology and center games Assessments: Topic 5 Assessment Addition/Subtraction fluency quizzes Interdisciplinary Connections: N/A Additional Resources: (Math games) Pearson, enVisionmath2.0 Subject: Mathematics Grade: 2 Suggested Timeline: 9 days 6: Fluently Subtract Within 100 Topic 6 Overview/Essential Understanding: Sometimes it is necessary to regroup when subtracting. The standard subtraction algorithm can be used to break the calculation into simpler steps, starting with the ones and moving to the tens. The inverse relationship between addition and subtraction can be used to solve and check subtraction. Bar diagrams, equations, and objects can be helpful when solving one and two-step word problems. Good math thinkers know how to think about words and numbers to solve problems. Topic 6 Objectives:
