Quiz with a bit on order of operations and evaluation, but mostly focusing on number systems and their differences i.e. why a sample integer may or may not also be a whole number; also some plotting and ordering numbers on a number line. Editable Microsoft Word (with MathType) file, usually two pages. With my scanned (hand-written) answer keys (PDF format).
