GEOMETRIC & SPATIAL REASONING – SORTING SHAPES, LINES OF SYMMETRY, PARTITIONING CIRCLES AND RECTANGLES
- 2.GSR.7.1 Describe, compare and sort 2-D shapes including polygons, triangles, quadrilaterals, pentagons, hexagons, and 3-D shapes including rectangular prisms and cones, given a set of attributes.
- 2.GSR.7.2 Identify at least one line of symmetry in everyday objects to describe each object as a whole.
- 2.GSR.7.3 Partition circles and rectangles into two, three, or four equal shares. Identify and describe equal-sized parts of the whole using fractional names (“halves,” “thirds,” “fourths”, “half of,” “third of,” “quarter of,” etc.).
- 2.GSR.7.4 Recognize that equal shares of identical wholes may be different shapes within the same whole.
MEASUREMENT & DATA REASONING – LENGTH, DISTANCE, TIME, AND MONEY
- 2.MDR.5.1 Construct simple measuring instruments using unit models. Compare unit models to rulers.
- 2.MDR.5.2 Estimate and measure the length of an object or distance to the nearest whole unit using appropriate units and standard measuring tools.
- 2.MDR.5.3 Measure to determine how much longer one object is than another and express the length difference in terms of a standard-length unit.
- 2.MDR.5.4 Ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life.
- 2.MDR.5.5 Represent whole-number sums and differences within a standard unit of measurement on a number line diagram.
- 2.MDR.6.1 Tell and write time from analog and digital clocks to the nearest five minutes, and estimate and measure elapsed time using a timeline, to the hour or half hour on the hour or half hour.
- 2.MDR.6.2 Find the value of a group of coins and determine combinations of coins that equal a given amount that is less than one hundred cents, and solve problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.
NUMERICAL REASONING – COUNTING WITHIN 1000, PLACE VALUE, ADDITION AND SUBTRACTION, FLUENCY TO 20, DEVELOPING MULTIPLICATION THROUGH ARRAYS
- 2.NR.1.1 Explain the value of a three-digit number using hundreds, tens, and ones in a variety of ways.
- 2.NR.1.2 Count forward and backward by ones from any number within 1000. Count forward by fives from multiples of 5 within 1000. Count forward and backward by 10s and 100s from any number within 1000. Count forward by 25s from 0.
- 2.NR.1.3 Represent, compare, and order whole numbers to 1000 with an emphasis on place value and equality. Use >, =, and < symbols to record the results of comparisons.
- 2.NR.2.1 Fluently add and subtract within 20 using a variety of mental, part-whole strategies.
- 2.NR.2.2 Find 10 more or 10 less than a given three-digit number and find 100 more or 100 less than a given three-digit number.
- 2.NR.2.3 Solve problems involving the addition and subtraction of two-digit numbers using part-whole strategies.
- 2.NR.2.4 Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
- 2.NR.3.1 Determine whether a group (up to 20) has an odd or even number of objects. Write an equation to express an even number as a sum of two equal addends.
- 2.NR.3.2 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.
2.PAR
PATTERNING & ALGEBRAIC REASONING – PATTERNS UP TO 20 AND ADDITION AND SUBTRACTION WITHIN 1,000

PATTERNING & ALGEBRAIC REASONING – PATTERNS UP TO 20 AND ADDITION AND SUBTRACTION WITHIN 1,001
- 2.PARb.4 Identify, describe, extend, and create repeating patterns, growing patterns, and shrinking patterns.
