Operations and Algebriac Thinking
Part 2
(January  February) 
 Use addition and subtraction within 100 to solve 1 and 2 step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.
 Fluently add and subtract within 20 using mental strategies.
 Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.
 Understand that the 3 digits of a 3 digit number represent amounts of hundreds, tens, and ones.
 Count within 1000; skipcount by 5s, 10s, and 100s.
 Read and write numbers to 1000 using baseten numerals, number names, and expanded form.
 Compare two 3 digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
 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.
 Mentally add 10 or 100 to a given number 100900, and mentally subtract 10 or 100 from a given number 100900.

Measurement
(April) 
 Fluently add and subtract within 20 using mental strategies.
 Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
 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.
 Estimate lengths using units of inches, feet, centimeters, and meters.
 Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
 Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units.
 Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points and represent whole number sums and differences within 100 on a number line diagram.
 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.

(May) 
 Fluently add and subtract within 20 using mental strategies.
 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.
 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths.
 Recognize that equal shares of identical wholes need not have the same shape.
