OPERATIONS & ALGEBRAIC THINKING  

Represent and solve problems involving addition and subtraction  
2OA1. Use addition and subtraction within 100 to solve one and twostep word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

Work with equal groups of objects to gain foundations for multiplication  
2OA3. Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.  Odd + Odd is the Same as* Odds and Evens 

2OA4. Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.  Multiplication Array  
NUMBER AND OPERATIONS IN BASE 10  
Understand place value  
2NBT1. Understand that the three digits of a threedigit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. 2NBT1a. 100 can be thought of as a bundle of ten tens — called a “hundred.” 2NBT1b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).

2NBT7. Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting threedigit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

MEASUREMENT AND DATA  
Measure and estimate lengths in standard units  
2MD1. Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. 


2MD2. Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.  Measuring in Inches and Centimeters  
2MD3. Estimate lengths using units of inches, feet, centimeters, and meters.  Estimating and Measuring – Centimeters* Estimating and Measuring – Feet* Estimating and Measuring – Inches* Estimating and Measuring – Meters* Finding Foot Measurements Finding Meter Measurements 

2MD4. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. 
Comparing Measurements – Centimeters Comparing Measurements – Inches 

Relate addition and subtraction to length  
2MD5. Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem. 
Addition and Subtraction Length Word Problems  one step Addition and Subtraction Length Word Problems  two step* 

2MD6. Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …, and represent wholenumber sums and differences within 100 on a number line diagram.  Number Line Riddles

Represent and interpret data  
2MD9. Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in wholenumber units.
