Do you need a quick assessment to see if your students know their basic subtraction facts? Are you running out of your quota of paper to make copies for those tests?
Each page of these timed subtraction mini-tests contain four different columns. Each column is a mini-test. Make copies and cut each page into 4 different strips. You may want to create a folder for each fact to store the extra strips of paper. Periodically, there are review mini-tests which combines facts from two different tests.
The 2s page contains an A List, B List, C List, and D List. Each list has 21 problems of adding 2 to a number. The next page is the 3s and it has an A List, B List, C List, and D List. Each list contains 21 problems. Then you'll see a review test of the 2s and 3s in four columns with 21 problems in each column.
I had my students complete a strip of problems in 2 minutes. (You could choose any amount of time you wish.) At the end of 2 minutes I took up the tests. Those students who made 100% did not have any basic facts homework that night. Those students then went to the next set of facts, such as the 3s. If a student missed any of the problems in that stack, then that student wrote just the facts that she missed. The next day, that student was tested on that set again using a different list from that page.
I don't keep all students on the same set of facts. Students who make 100% go on to the next set of facts. (Don't use each column for a child who is doing well. You'll want those children who do well to go to the next set of facts.) So, I would have several students on the 2s, some on the 3s, a few on the 4s, and then some on the 3s and 4s. When finished with all of the subtraction facts, the student then goes on to the multiplication timed mini-tests (sold separately). I use a class chart with each student's name to manage where each student is and to track progress. I wrote the number missed under each heading by that child’s name. When that homework was turned in, I circled the number missed to show that homework was completed.
Basic subtraction mini-tests are appropriate for grades 1 - 5 and above. Even older students lack a strong foundation of basic facts. You'll probably want to download the addition mini-tests as well.
