=Operations & Algebraic Thinking=

2.OA.1 Using addition and subtraction within 100 to solve 1 and 2 step word problems 2.OA.2 Fluently add and subtract within 20 using mental strategies 2.OA.3 Determine whether a group of objects is odd or even 2.OA.4 Use addition to find the number of objects arranged in a rectangular array; write a number sentence

=Number & Operations in Base Ten= 2.NBT.1 Understands that the three digits of a three digit number represent amounts of hundreds, tens and ones. 2.NBT.1a 100 can be thought of ass a bundle of ten 10s

2.NBT.1b The numbers 100-900 refer to one, two, three, hundreds

2.NBT.2 Count within 100; skip count by 5s, 10s and 100s 2.NBT.3 Read and write numbers to 1000 using base ten numerals, number names and expanded form.

2.NBT.4 Compare two three-digit numbers using < > =. 2.NBT.5 Fluently add and subtract within 100 using strategies based on place value, properties of operations and the relationship between addition and subtraction. 2.NBT.6 Add up to four two-digit numbers using strategies based on place value and properties of operations. 2.NBT.8 Mentally add/subtract 10 or 100 to a given number.

2.NBT.9 Explain why addition and subtraction strategies work, using place value and properties of operations.

=Measurement & Data= 2.MD.1 Measure the length of an object by selecting and using appropriate tools. 2.MD.2 Measure the length of an object twice using different units; describe how the two measurements relate to the size of the unit.

2.MD.3 Estimate lengths using units of inches, feet, centimeters, and meters.

2.MD.4 Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard unit.

2.MD.5 Use addition/subtraction within 100 to solve word problems involving lengths that are given in the same units.

2.MD.6 Represnt whole numbers as lenghts from 0 on a number line diagram with equally spaced points corresponding to the numbers 0,1,2,3...and represent whole number sums and differences within 100 on a number line.

2.MD.7 Tell and write time from analog and digital clocks to the nearest 5 minutes using am/pm

2.MD.8 Solve word problems involving dollar bills, quarters, dimes, nickels and pennies using $/cents sign. 2.MD.9 Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated maeasuremetns of the same object. Show the measurements by making a line plot marked off in whole number units.

2.MD.10 Draw a picture graph and bar graph with single scale to represent a data set with up to four categories. Solve simple put together, take apart, and compare problems using information from the graph.

=Geometry= 2.G.1 Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes 2.G.2 Partition a rectangle into rows and columns of the same size wquares and count to find the total number of them.

2.G.3 Partition circles and rectangles into two, three, or four equal shares, describet he shares using words halves, thirds, half of, a third etc; describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical whols need not have the same shape. ==
