Unit 1 Chapter 16 9 days Chapter 17 8 days | 1.NS.A.2 - Read, write, and represent a number of objects within a written numeral using numbers up to 120; count backwards from 20 (1.NS.A.3) 1.NBT.A - Understand place value of two-digit numbers.
2.NBT.B.8 - Use place value understanding and properties of operations to add and subtract, demonstrating fluency within 100. 2.RA.A.1 - Demonstrate fluency with addition and subtraction within 20. | Chapter 16: Numbers to 120 - This chapter lays the foundation for developing addition and subtraction skills with larger numbers, a skill that they will learn in the next chapter. Chapter 17: Addition and Subtraction to 100 - This chapter should be developed conceptually; the abstract paper pencil algorithm is not necessary to be mastered. Students should understand regrouping and place value as the work with addition and subtraction, but at the concept level. | Chapter 16: Numbers to 120-

Unit 2 Chapter 1 11 days Chapter 2 11 days Chapter 3 13 days Chapter 4 10 days | 2.NBT.A.4 - Read and write numbers to 1000 using number names, base-ten numerals and expanded form. 2.NBT.A.5- Compares two 3-digit numbers using symbols <, >, = 2.NBT.C.11 - Write and solve problems involving addition and subtraction within 100 to solve one-step word problems. 2.NBT.B.8 - Use place value understanding and properties of operations of three digit numbers to add and subtract within 1000 and justify the solution 2.NBT.B.9- Uses the relationship between addition and subtraction to solve problems ��2.RA.A.1 - Demonstrate fluency with addition and subtraction within 20. | Chapter 1: Numbers to 1000 - Chapter 1 is an extremely important chapter. Students will jump into large numbers quickly. Students will be expected to read, write, and work with numbers to 1,000. They will be ordering and comparing numbers and identifying number patterns. Chapter 2: Addition up to 1000 - Chapter 2 is to continue with the place value understanding and regrouping in ones, tens, and hundreds. The focus for this chapter is on developing place value. Practice with counting (forward and backwards by 1, 10, 100’s). Chapter 3: Subtraction to 1000 - Chapter 3 (subtraction up to 1,000) consists of students working with subtraction, regrouping ones, tens, and hundreds. In addition, they will be subtracting with regrouping across zeros. Chapter 4: Using Bar Models (+ and -) - Many students will be able to solve problems without the use of a bar model. Encourage all students to both solve a problem, as well as to draw a bar model. Exposure to bar modeling and the ability to represent the math is what is important here, along with the problem solving components. Chapter 4 includes both part-part whole word problems and additive comparison problems. The latter are more difficult. More practice will be provided in later chapters. | Chapter 1: Numbers to 1000-

Unit 3 Chapter 18 4 days Chapter 19 7 days Pull in vocabulary from Ch. 18 as needed Chapter 5 8 days Chapter 6 12 days� | 2.GM.A.1 - Recognize and draw shapes having specified attributes, such as a given number of angles or sides. Identify the faces of 3-D shapes. � RA.B.2.c - Develop foundations for multiplication and division determine if a set of objects has an odd or even number or members, Express even numbers as being composed of equal groups and write an expression to represent the number with 2 equal addends. 2.RA.B.3- Find the total number of objects arranged in a rectangular array with up to 5 rows and 5 columns, and write an equation to represent the total as a sum or equal addends.��2.NBT.C.11 - Write and solve problems involving addition and subtraction within 100 to solve one-step and two-step word problems.� | Chapter 18: Lines and Surfaces - Chapter 18 focuses on recognizing, identifying, and drawing parts of lines and curves. Students also are working on identifying and counting flat fluency, along with mental math and estimation strategies. Chapter 19: Shapes and Patterns - Recognizing, identifying, and drawing plane shapes and recognizing and identifying solid shapes are important big ideas in chapter 19. Chapter 5: Multiplication and Division - This chapter addresses the key multiplication concepts in the MLS for 2nd grade. These include using equal groups and repeated addition to multiply as well as identifying real-world problems that can be solved by multiplication. It is taught here at the introductory conceptual level as sharing or of equal groups. Chapter 6: Multiplication Tables 2, 5, 10 - The focus for chapter 6 (mult. Tables of 2, 5, 10) is to develop an understanding of multiplication and division of 2, 5, 10. It is not about fact mastery. The content is not expected to be mastered by all students. The focus of this chapter is on informal array models to present multiplication facts. Also students learn to use a known fact to calculate an unknown one (if 2 x 2 = 4, then 3 x 2 = one more 2 or 6). Skip counting 2’s, 5’s, 10’s, is also emphasized in the chapter. | Chapter 18: Lines and Surfaces-

And analyze the results of measuring the same object with different units | Chapter 7: Metric Measurement of Length- In addition to working with metric measurement, Chapter 7 provides for a meaningful way for students to continue to work with addition and subtraction, along with bar models. Chapter 13: Customary Measurement Length - The basic units of length in the customary system are feet and inches. The big ideas within this chapter are about measuring in feet and inches, comparing lengths and solving problems regarding length. Chapter 10: Mental Math and Estimation - Skills and concepts within chapter 10 should be reinforced all year, so do not get stuck in this chapter. The focus of chapter 10 is to enable students to become more flexible and fluent with their thinking. Students do not need to master all strategies presented. This chapter is about thinking flexibility and fluency. | Chapter 7: Metric Measurement of Length-
