This math fact sheet has two different sets of problems on it. Each set has 20 different addition equations. There are vertical and horizontal addition equations to help the students see addition equations in two different ways. This is a great way to practice addition because you can choose what addend your student needs to work on and have them practice that number by filling in the blank addend on every equation. First you put the addend in the box at the top of the page or tell your student what number to work on and then the student writes the addend in the empty addend spot of the addition equation (before you time them). I always start all of my students on the 1s addition facts. I use this addition fact sheet as a timed test and I give my students one and a half minutes to complete their timed test. If the student completes the timed test and misses 0 facts or 1 fact, I have them move on to the next addend number. So if the student misses just one or doesn't miss any of the 1s equations, they get to go on to 2s and so on. I use a student list and color in the number they passed with a Sharpie. This shows me the progress of each student by using a bar graph and it's easier to tell the students what number they are on. This classroom list is also included. Just add your students' names and you are ready to go. This math facts activity makes it so that all my students are working on the number they need to and at their own pace. I teach second grade so I usually stop at 12s. These math facts can also be used in many other grades and for practice too!!
