2.NBT.7 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 three-digit 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.

(B) Describe the inverse relationship between the size of the unit and the number of units needed to equal the length of an object

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.

(A) Determine the value of a collection of coins up to one dollar

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?

(B) Use the cent symbol, dollar sign, and the decimal point to name the value of a collection of coins.

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?

(D) Determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes

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

(D) Determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes

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

(A) Find the length of objects using concrete models for standard units of length

2.MD.1 Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

(C) Write and solve one-step word problems involving addition or subtraction using data represented within pictographs and bar graphs with intervals of one

2.MD.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph.

(G) Read and write time to the nearest one-minute increment using analog and digital clocks and distinguish between a.m. and p.m.

(Y2) Tell time to the quarter-hour, using the language of 'past' and 'to' (ACMMG039)

2.MD.7 Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

(B) Organize a collection of data with up to four categories using pictographs and bar graphs with intervals of one or more

2.MD.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph.

(E) Determine a solution to a problem involving length, including estimating lengths

(Y2) Compare and order several shapes and objects based on length, area, volume and capacity using appropriate uniform informal units (ACMMG037)

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.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.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 whole-number sums and differences within 100 on a number line diagram.

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 whole-number units.

2.MD.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 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. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

(F) Use concrete models of square units to find the area of a rectangle by covering it with no gaps or overlaps, counting to find the total number of square units, and describing the measurement using a number and the unit

(Y2) Compare and order several shapes and objects based on length, area, volume and capacity using appropriate uniform informal units (ACMMG037)

2.G.2 Partition a rectangle into rows and columns of same-size 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.
