Do you need a quick assessment for the Dewey Decimal system before you teach each section? I use this to pre-test and then again to post-test after doing the Dewey Decimal scavenger hunts. There are 4 questions. Students read the title and circle the correct call number. A Dewey Decimal key is included at the top. An answer key is included for your convenience. There are 4 assessment sheets and they are all different to minimize copying your neighbor.
