• 2.PAR.4.10/3

  Identify, describe, and create a numerical pattern resulting from repeating an operation such as addition and subtraction.

• 2.PAR.4.20/1

  Identify, describe, and create growing patterns and shrinking patterns involving addition and subtraction up to 20.

• 2.MDR.5.10/1

  Construct simple measuring instruments using unit models. Compare unit models to rulers.

• 2.MDR.5.20/3

  Estimate and measure the length of an object or distance to the nearest whole unit using appropriate units and standard measuring tools.

• 2.MDR.5.30/1

  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.5.40/4

  Ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life.

• 2.MDR.5.50/4

  Represent whole-number sums and differences within a standard unit of measurement on a number line diagram.

• 2.MDR.6.10/5

  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.6.20/5

  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.

• 2.GSR.7.10/4

  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.7.20/1

  Identify at least one line of symmetry in everyday objects to describe each object as a whole.

• 2.GSR.7.30/1

  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.7.40/1

  Recognize that equal shares of identical wholes may be different shapes within the same whole.
