4 sets of tests for each number are included on each page so they can be cut into strips. Numbers 1-10 are included as well as doubles. I pass them out and set the timer for one minute. When the timer goes off, they have to hold their pencils up. If they got all of them right in one minute, they move up to the next number the next day that we do it. If they don't, they stay at their number. We use a sticker chart to track progress.
