This mathematical task aligns with Common Core Standards. In the task, students order numbers through 1,000. The following is the introduction to the task:
library books. The machine reads the numbers on the spine and then sorts the books two times.
The first sort puts the books into bins as the numbers fit into hundreds. For example, a book with the number 457 on it would slide into the 400-499 bin. The second sort puts the books in each bin in order from least to greatest. For example, if the books 478, 456, 457, and 413 are in the bin, they will be sorted like this:
413 < 456 < 457 < 478
Now look at the list below, sort the books twice. The first sort will place the books in the correct hundred. During the second sort, you will order the numbers from least to greatest.
