2.GM.G.3
Compose geometric shapes having specified geometric attributes, such as a given number of edges, angles, faces, vertices, and/or sides.
Taught inNaming flat shapes Turned, still a square Count sides, not looks Sorting shapesand 1 more
2.NO.NF.2
Recognize that identical wholes can be equally divided in different ways.
Taught inHalves, thirds, and fourths Same size, different shapes Equal without matching Equal parts only
2.NO.NF.3
Recognize that partitioning shapes into more equal shares creates smaller shares.
Taught inHalves and fourths Equal parts only Many ways to make halves

Operations and Algebraic Thinking

2.AR.OA.1
Automatically add and subtract within 20.
Taught inA fact you know beats counting Subtraction is a missing part Make a ten to add Doubles and near doubles

Solve one- and two-step authentic word problems with addition within 100, including use of unknowns.
Taught inTwo-step word problems A story for an equation The total is already there Act out the storyand 3 more
2.AR.OA.4
Solve one- and two-step authentic word problems with subtraction within 100, including use of unknowns.
Taught inTwo-step word problems A story for an equation The total is already there Act out the storyand 3 more
2.AR.OA.5
Use repeated addition to find the total number of objects arranged in a rectangular array.
Taught inEqual groups, added again Rows and columns Add the rows, not the sides Count the inside dots too
2.AR.OA.6
Identify a group of objects from 0 to 20 as even or odd by showing even numbers as a sum of two equal parts.
Taught inEven or odd?Even numbers end the same way Doubles are always even

Measurement and Data

2.GM.M.1
Measure the length of an object using two different standard units of measurement. Describe how the two measurements relate to the size of the units chosen.
Taught inBigger unit, fewer units
2.GM.M.2
Estimate and measure to determine how much longer one object is than another, expressing the difference with a standard unit of measurement.
Taught inMeasuring with a ruler Start at zero Count the inches, not the marks Pick the tool and the unitand 3 more
2.GM.M.3
Tell and write time to the nearest five minutes (including quarter after and quarter to) with a.m. and p.m. using analog and digital clocks.
Taught inTime to five minutes Short hand, long hand Almost the next hour Half past and quarter afterand 1 more
2.GM.M.4
Count collections of money (quarters, dimes, nickels, and pennies) relating to counting patterns by 1s, 5s, and 10s up to one dollar.
