• CCSS.MATH.CONTENT.1.MD.B.3

  Tell and write time in hours and half-hours using analog and digital clocks.

  In Grade 1Standards for Mathematical PracticeMeasurement & DataTell and write time
• CCSS.MATH.CONTENT.2.OA.C.3

  Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.

  In Grade 2Standards for Mathematical PracticeOperations & Algebraic ThinkingWork with equal groups of objects to gain foundations for multiplication
• CCSS.MATH.CONTENT.2.OA.C.4

  Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.

• CCSS.MATH.CONTENT.2.NBT.A.1

  Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:

• CCSS.MATH.CONTENT.2.NBT.B.5

  Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

  In Grade 2Standards for Mathematical PracticeNumber & Operations in Base TenUse place value understanding and properties of operations to add and subtract
• CCSS.MATH.CONTENT.2.NBT.B.6

  Add up to four two-digit numbers using strategies based on place value and properties of operations.

• CCSS.MATH.CONTENT.2.MD.A.1

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

  In Grade 2Standards for Mathematical PracticeMeasurement & DataMeasure and estimate lengths in standard units
• CCSS.MATH.CONTENT.2.MD.A.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.

  In Grade 2Standards for Mathematical PracticeMeasurement & DataMeasure and estimate lengths in standard units
• CCSS.MATH.CONTENT.2.MD.B.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.

  In Grade 2Standards for Mathematical PracticeMeasurement & DataRelate addition and subtraction to length
• CCSS.MATH.CONTENT.2.MD.C.7

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

  In Grade 2Standards for Mathematical PracticeMeasurement & DataWork with time and money
• CCSS.MATH.CONTENT.2.MD.C.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?

• CCSS.MATH.CONTENT.2.MD.D.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.

  In Grade 2Standards for Mathematical PracticeMeasurement & DataRepresent and interpret data
• CCSS.MATH.CONTENT.2.G.A.2

  Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

  In Grade 2Standards for Mathematical PracticeGeometryReason with shapes and their attributes
• CCSS.MATH.CONTENT.2.G.A.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 id...
