Topic: Measurement and Data |
Common Core Mathematics K-2 |
| Cluster Describe and compare measurable attributes. |
| | Kindergarten |
| | | K.MD.1. | Describe measurable attributes of objects, such as length or weight.
Describe several measurable attributes of a single object. |
| | | K.MD.2. | Directly compare two objects with a measurable attribute in common,
to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter. |
| Cluster Classify objects and count the number of objects in each category. |
| | Kindergarten |
| | | K.MD.3. | Classify objects into given categories; count the numbers of objects in
each category and sort the categories by count.[Limit category counts to be less than or equal to 10.] |
| Cluster Measure lengths indirectly and by iterating length units. |
| | Grade 1 |
| | | 1.MD.1. | Order three objects by length; compare the lengths of two objects
indirectly by using a third object. |
| | | 1.MD.2. | Express the length of an object as a whole number of length units, by
laying multiple copies of a shorter object (the length unit) end to end;
understand that the length measurement of an object is the number
of same-size length units that span it with no gaps or overlaps. Limit to
contexts where the object being measured is spanned by a whole number of
length units with no gaps or overlaps. |
| Cluster Tell and write time. |
| | Grade 1 |
| | | 1.MD.3. | Tell and write time in hours and half-hours using analog and digital
clocks. |
| Cluster Represent and interpret data. |
| | Grade 1 |
| | | 1.MD.4. | Organize, represent, and interpret data with up to three categories; ask
and answer questions about the total number of data points, how many
in each category, and how many more or less are in one category than in
another. |
| Cluster Measure and estimate lengths in standard units. |
| | Grade 2 |
| | | 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. |
| Cluster Relate addition and subtraction to length. |
| | Grade 2 |
| | | 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 whole-number sums and differences within 100 on a number
line diagram. |
| Cluster Work with time and money. |
| | Grade 2 |
| | | 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 ยข symbols appropriately. Example: If you have 2
dimes and 3 pennies, how many cents do you have? |
| Cluster Represent and interpret data. |
| | Grade 2 |
| | | 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 problems using information
presented in a bar graph. |
