Unit 1- Using Place Value to Add and Subtract : Second grade students will build upon their place value knowledge to 10 and expand it to 1,000. Students will represent numbers in multiple ways. Students will apply their understanding of place value to compare and order numbers. Students will develop and refine strategies for addition and subtraction within 20 working toward fluency by the end of second grade.
Vocabulary: place value, ones, tens, hundreds, count on, count back, even, odd, digit, expanded form, more, fewer, addition, subtraction, plus, minus, equal, sum, addends, difference, doubles, related facts, equation, compare, is greater than (>), is less than (<), is equal to (=), thousand, digits, even numbers, odd numbers
Unit 2- Shapes and Attributes: Second grade students will reason with shapes and their attributes by identifying shapes such as triangles, quadrilaterals, pentagons, hexagons, and cubes and drawing these shapes with specified attributes such as number of sides, angles, and/or faces. Students will partition a rectangle into rows and columns of same-size squares and partition circles and rectangles into halves, thirds, and fourths.
Vocabulary: angle, cone, cube, cylinder, edge, face, fourths, halves, hexagon, pentagon, quadrilateral, prism, side, sphere, thirds, vertex, half of, third of, fourth of, quarter of, equal parts, whole, rows, columns, rectangle, array, equal shares

Unit 3: Addition and Subtraction within 100: Students will apply place value understanding and properties of addition and subtraction to solve real world problems. They will start to apply various strategies based on number sense, mental math, and the relationship between addition and subtraction with sums to 100. Students will use their place value knowledge to add and subtract with composing or decomposing ones and tens within 100. They will represent numbers in multiple ways, develop and refine strategies for addition and subtraction within 20 working toward fluency by the end of second grade.
Vocabulary: regroup, tens, ones, difference, digits, bar model, equations, subtract, difference, place value, hundred, sum, addend
Unit 4: Represent and Interpret Data: In this unit students will learn how to organize, represent, and interpret data. They will use the data found within bar graphs, picture graphs and line plots to make sense of the information presented while communicating and explaining details within the categories. Students will also be expected to draw picture graphs and bar graphs. Solving common addition and subtraction situations using the data is also an expected in this unit. *Please note that in this unit students are introduced to reading and interpreting line plots. They will expected to make line plots in unit 6 after measuring lengths in order to complete the expectation of this cluster. Introducing students to line plots in this unit will support a progressional transition to 2.MD.4.9 standard in unit 6.
Vocabulary: categories, labels, titles, data, collect, record, analyze, compare, represent, bar graph, picture graph, line plot, survey, tally chart, tally marks, key
Unit 5: Time and Money: Second grade students will build on their understanding of digital and analog clocks. They will be able to tell and write time to the hour, half hour, quarter hour and nearest five minutes. During this unit, students will identify the value of coins and paper currency. They will combine or take apart coins or paper currency to add and subtract money. After adding and subtraction money students will be introduced to solving word problems involving the common addition and subtraction situations involving money.
Vocabulary: minute, quarter past, half past, hour hand, minute hand, noon, midnight, cent sign, dime, penny, nickel, quarter, dollar sign, dollar, compare, change, difference, total, sum
Unit 6: Measure and Estimate Lengths in Standard Units - Second grade students will build on their understanding of length measurement, the connection between measurement tools, and the number line. They will begin to use varying sizes of standard measurement units including: inches, feet, yards, centimeters, and meters. They will also use a variety of length measurement tools, such as rulers, meter sticks, yard sticks, and measuring tapes. Second grade students will understand that the smaller the unit, the more iterations of the unit are needed to cover a given length. Students will also revisit the concepts involving data in unit 4 as they organize and represent measurement data using a line plot to more deeply connect the number line as a useful mathematical tool.
Vocabulary: nearest whole unit, foot (feet), inch(es), centimeter(s), meter(s), length, measuring tape, yardstick, ruler, line plot, data, categories, number line
Unit 7: Addition and Subtraction within 1,000 - In this unit students should be applying all the knowledge they have gathered over the course of the year; and the experience they have developed using physical models to build place value understanding and fluency. Students should utilize their place value understanding and computational fluency to add and subtract with composing or decomposing tens or hundreds within 1,000. Students should represent sums, differences, and/or strategies for computation in multiple ways. They will apply their knowledge to solve word problems and continue to develop and refine strategies for addition and subtraction within 1,000 while demonstrating fluency within 20 using mental strategies.
Vocabulary: one thousand, hundreds, tens, ones, addends, sum, regroup, difference, compare
