These packets were designed to help students memorize their subtraction facts. There are several different types of packets available. Some packets focus on just one subtrahend (e.g., subtracting 3s) and other packets are mixed (e.g., all of the possible 1-10 subtraction facts). Some packets contain 40 problems per page and other contain 100 problems per page.
We typically have students do a page from a mixed 1-10 packet first to determine which facts they need to work on. However, because students memorize math facts fastest through extended repetition, we recommend that once you a identify the specific numbers the student needs to work on, work on packets designed explicitly for that number. Packets contain between 400 and 1,000 problems. Students who do all off these problems (with checks for accuracy) quickly master all of their addition facts. And, from there, they see huge time and accuracy increases in the rest of their math work.
Ideally, students should be able to complete about 20 problems a minute. So, 40 problem pages should be completed in 2 minutes and 100 problem pages should be completed in 5 minutes. If a student finishes a packet without achieving mastery (100% correct under the time limit), reprint the packet and keep working. The practice will pay off!
There are many different packets to choose from below, including both mixed packets and packets that focus on an individual number's subtraction facts. Each page has a random set of 40 or 100 problems. Each page also has a speed and accuracy guide, to help students see how fast and how accurately they should be doing these problems. After doing all of the practice problems, students should have memorized their 1-10 subtraction facts.
