MD-Describe+and+compare+measurable+attributes

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.// 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). || ===**Anchor Standard/Mathematical Practice(s)**=== K.MP.7.

Essential Vocabulary

 * compare, length, weight, attribute, data,sort

Sample Assessments

 * Have students order four or five classmates by their height.
 * Classify objects into specific categories and explain how items were sorted.
 * <span style="font-family: Arial,Helvetica,sans-serif;">Describe similarities and differences of two common objects or shapes (e.g., 2 books, 2 pencils).

<span style="font-family: Arial,Helvetica,sans-serif;">Differentiation

 * <span style="font-family: Arial,Helvetica,sans-serif;">Model comparing the length of an object to the pencil. Have each student choose a classroom object and compare length to the pencil.
 * <span style="font-family: Arial,Helvetica,sans-serif;">Have students draw three different lines on their dry erase board. Have students cover up the bottom line and compare the other two by marking the longer line. Next repeat by covering up a different line and then comparing the two remaining.
 * <span style="font-family: Arial,Helvetica,sans-serif;">Give students paper clips and have link them together and measure a classroom object (e.g. crayons, desk, etc.)

<span style="font-family: Arial,Helvetica,sans-serif;">Intervention:

 * <span style="font-family: Arial,Helvetica,sans-serif;">Students having difficulty deciding which object is shorter or longer than an object, then show two cube trains that are the same length. Then remove some cubes from one train and discuss how the length has changed.
 * <span style="font-family: Arial,Helvetica,sans-serif;">Place strips of paper of diffeent lengths in a bag. Ask students to choose three strips. Eash student orders the strips from shortest to longest.

<span style="font-family: Arial,Helvetica,sans-serif;">Enrichment:
> sets of data.
 * <span style="font-family: Arial,Helvetica,sans-serif;">Students build a structure from legos or cubes to see whose will be the longest or tallest.
 * <span style="font-family: Arial,Helvetica,sans-serif;">The student solves problems by collecting, organizing, displaying, and interpreting

<span style="font-family: Arial,Helvetica,sans-serif;">Notes and Additional Information
<span style="font-family: Arial,Helvetica,sans-serif;">Students describe measurable attributes of objects, such as length, weight, size, and color. For example, a student <span style="font-family: Arial,Helvetica,sans-serif;">may describe a shoe with one attribute, “Look! My shoe is blue, too!”, or more than one attribute, “This shoe is <span style="font-family: Arial,Helvetica,sans-serif;">heavy! It’s also really long.”

<span style="font-family: Arial,Helvetica,sans-serif;">Direct comparisons are made when objects are put next to each other, such as two children, two books, two <span style="font-family: Arial,Helvetica,sans-serif;">pencils. For example, a student may line up two blocks and say, “The blue block is a lot longer than the white <span style="font-family: Arial,Helvetica,sans-serif;">one.” Students are not comparing objects that cannot be moved and lined up next to each other.

<span style="font-family: Arial,Helvetica,sans-serif;">Students identify similarities and differences between objects (e.g., size, color, shape) and use the identified <span style="font-family: Arial,Helvetica,sans-serif;">attributes to sort a collection of objects. Once the objects are sorted, the student counts the amount in each set. <span style="font-family: Arial,Helvetica,sans-serif;">Once each set is counted, then the student is asked to sort (or group) each of the sets by the amount in each set.
