Develop an understanding of linear measurement and describe and analyze shapes.
Estimate, measure and compute lengths to solve problems. (use a number line, ruler and other measuring tools)
Reason with shapes and their attributes:
Describe and analyze shapes by examining their sides and angles.
Decompose and combine shapes to make other shapes.
Formulate survey questions. [use tallies, bar graphs (categorical), pictographs]
Graph data. (categorical  e.g. What is your favorite color? numerical  e.g. What is the average height of a 2^{nd} grader?)

2.MD.1   Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. 
2.MD.2   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. 
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 length unit. 
2.MD.5   Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem. 
2.MD.6   Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and represent wholenumber sums and differences within 100 on a number line diagram. 
2.MD.7   Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m. 
2.MD.8   Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have? 
2.MD.9   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. 
2.MD.10   Draw a picture graph and a bar graph (with singleunit scale) to represent a data set with up to four categories. Solve simple put together, takeapart, and compare problems using information presented in a bar graph. 
2.G.1   Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. 
2.G.2   Partition a rectangle into rows and columns of samesize squares and count to find the total number of them. 
2.G.3   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.

Misconception Alerts:
Students in second grade will be exploring, describing and analyzing 2D and 3D shapes. This is continued exposure ONLY and readiness for geometry in higher grades. Vocabulary listed in the vocabulary section of this document is the only vocabulary that students should be exposed to.
