<p> CCSS Mathematics Assessment Task Comparison Grade Level: 2</p><p>Mathematics Domain and Cluster: Domain: Number and Operations in Base Ten Cluster: Understand Place Value Common Core standard(s) being assessed (if the task is intended to assess only one part of the standard, underline that part of the standard): 2.NBT.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: a. 100 can be thought of as a bundle of ten tens — called a “hundred.” b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight or nine hundreds (and 0 tens and 0 ones). 2.NBT.3 Read and write numbers to 1000 using base-ten numerals, number names, and expanded form. 2.NBT.4 Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, < symbols to record the results of comparisons. Student Materials:  Comparison assessment sheet  Pencil Differentiation Operation:  Base Ten Manipulatives (optional)</p><p>Teacher Materials:  Base Ten Manipulatives (optional)</p><p>Directions (for teacher to administer assessment task):  Pass out Comparison assessment sheet (one per student)  Tell students, “ You will need to identify and write the numbers, write the correct symbol in the blank and explain your second comparison using numbers or words.”  Read prompt aloud to students  Remind students, “Do not forget to write the correct numbers, write the correct symbol, and explain your second comparison using numbers or words.”  Have students work independently on the task. Differentiation Option:  Allow students to use base ten manipulatives.</p><p>Prompt: See attachment CCSS Mathematics Assessment Task</p><p>Correct or Model Answer:</p><p>I know that 324 is less than 326 because they both have three hundreds and two tens which are equal. But, 324 has only four ones and 326 has six ones. Since 4 is less than 6, I know that 324 is less than 326. </p><p>300 + 20 + 4 = 324 300 + 20 + 6 = 326 Both numbers have three hundred and twenty. But 324 has only 4 ones and 326 has 6 ones. Since 4 is less than 6, 324 is less than 326. </p><p>Scoring Guide/Rubric (a score should be awarded for each criterion below) – NOTE THAT THIS PARTICULAR RUBRIC ASSESSES AT THE CLUSTER LEVEL.
