Strategies for Addition & Subtraction Facts Within 18 is a second grade workbook which deals with two main themes: Mental math strategies for adding and subtracting within 0-20; such as adding just one more, a trickwith nine and eight, and subtracting using addition. Memorizing the basic addition and subtraction facts of single-digit numbers. In the first several lessons we study basic strategies for adding and subtracting within 0-20, such as adding one more, a "trick" for adding 9 or 8, subtracting to 10, and subtracting using addition. After those, we study the idea of completing ten and going over. For example, the child adds 8 + 5 by first adding 8 + 2 (which makes 10), and then adding the 3 that was "left over". All of these lessons in the beginning part prepare the student for the next part of the workbook, which has to do with memorizing the basic addition facts. The next lessons in the workbook, Adding with 9, Adding with 8, Adding with 7, and Adding with 6, provide lots of practice for learning and memorizing the basic addition facts. There are 20 such facts: from 9 + 2 to 9 + 9: 8 facts (lesson Adding with 9)from 8 + 3 to 8 + 8: 6 facts (lesson Adding with 8)from 7 + 4 to 7 + 7: 4 facts (lesson Adding with 7)from 6 + 5 to 6 + 6: 2 facts (lesson Adding with 6) Some children will accomplish this more quickly and need less practice. Some will need more practice. You can also add in some Internet-based games (a list of online games is provided). Learning and memorizing the basic addition and subtraction facts of single-digit numbers is very important for later study. For example, regrouping (carrying/borrowing) in addition and in subtraction requires that the student is able to recall all the sums of single-digit numbers and corresponding subtraction facts efficiently and fluently. The goal is to memorize these facts, or at least become so fluent with them that an outsider cannot tell if the student remembers the answer or uses some mental math strategy to get the answer.

Math Mammoth Add & Subtract 2-A deals with two main themes: strategies for adding and subtracting within 0-20; such as adding just one more, a trick with nine and eight, and subtracting using addition; memorizing the basic addition and subtraction facts of single-digit numbers with an answer between 10 and 18. While focusing on addition and subtraction techniques, the lessons also include many word problems. The goal is to memorize the facts, or at least become so fluent with them that an outsider cannot tell if the child remembers the answer or uses some mental math strategy to get the answer. Some children will accomplish this quicker and need less practice, whereas others will take longer. Thus, don't assign all the exercises in the book by default. Use your judgment, and try to match the amount of exercises to your child's need. The ones that don't get assigned can be used later for review. You can also use games to reinforce the facts, and in place of some of the exercises in the book (a list of games is provided in the book). Learning addition and subtraction facts is quite important for later study. For example, regrouping in addition and subtraction (carrying/borrowing) requires the ability to recall the basic facts efficiently and fluently. We will start the book with a few mental math strategies (Add Using "Just One More" and A Trick with Nine and Eight). The lesson Adding within 20 reviews those strategies and gives more practice. These initial lessons don't yet involve actual memorization techniques. The lesson Subtract to Ten explains another basic strategy, and has to do with subtracting in parts. For example, to do 13 - 5, one can subtract 5 in two parts: first do 13 - 3, which equals 10, and then subtract the rest, or 2 more. Memorizing the subtraction facts will be more efficient, but I want children to understand this strategy, because it is useful in many other situations also. Then we review how to complete the next whole ten, which is an important concept. An example of this concept is the question: What number do you add to 23 to get 30? As an equation, we write: 23 + __ = 30. In the next lesson, we study sums that go over ten, doing these sums in two parts. For example, in the sum 9 + 7, the child first completes 10 by adding 9 + 1. Then, the child adds the rest, or 6, to 10. Learning this prepares the child for addition facts where the sum is more than 10. The next lessons, Adding with 9, Adding with 8, Adding with 7, and Adding with 6, provide lots of practice for learning and memorizing the basic addition facts. There are 20 such facts: 9 + 2 till 9 + 9: 8 facts 8 + 3 till 8 + 8: 6 facts 7 + 4 till 7 + 7: 4 facts 6 + 5 till 6 + 6: 2 facts The last part of the book includes various lessons titled Number Rainbows and Fact Families with.... These give lots of practice and reinforcement for the basic addition and subtraction facts, emphasizing the connection between addition and subtraction as a strategy for subtraction facts. The follow-up to this book, Add & Subtract 2-B, practices adding and subtracting two-digit numbers mentally and in columns (regrouping).

The purpose of this study was to determine if supplementing the Regina math curriculum, Harcourt math 2004, with five different addition strategies, would improve computational fluency of addition math facts through the sum of 18 in my second grade classroom. The data was collected over a nine-week period during the fall semester of 2008-2009 school year at Regina Elementary in Iowa City, Iowa. Data sources for this study included daily lessons of each strategy, weekly addition assessments, and a pre-test/post test assessment. The 40-problem pre-test was administered at the beginning of the study and the same test was administered at the end of the study as a posttest. Other sources of data included a math graph for each student to record their weekly assessment scores. Each lesson in the study included direct instruction of the basic addition strategy, guided practice, hands-on activities, and cooperative learning activities in the classroom. After the posttest was administered to the subjects, findings suggest that this strategy-based instruction and guided practice did increase the computational fluency of my second grade students.

This book has more than 3100 subtraction facts for daily practice by students. Each page has 2 different sets consisting of 18 problems each. It is recommended for students to attempt 1 set daily for consistent practice. Book starts with addition strategies to help students grasp basic concepts and get started. Once students start gaining confidence in individual facts, they can review their knowledge by solving mixed facts. Book can be used to track practice time for each set. Date and time can be recorded at top of each page. Answer to each problem is given at the end of the book. Knowing subtraction facts is helpful not only in academics; we frequently use subtraction in our daily lives too. Just like learning to walk before you can run, learning subtraction and familiarizing yourself with numbers are building blocks for other math topics taught in school. Mastering the basic math facts develops automaticity in kids. Automaticity is the ability to do things without occupying the mind with the low level details that are required; this is usually the result of consistent learning, repetition, and practice. For instance, an experienced cyclist does not have to concentrate on turning the pedals, balancing, and holding on to the handlebars. Instead, those processes are automatic and the cyclist can concentrate on watching the road, the traffic, and other surroundings. Until students have developed sufficient sensory-cognitive tools supporting access to symbolic memory, they will not be able to image, store or retrieve all of the basic facts with automaticity. Therefore, students need a comprehensive, developmental, and multi-sensory structured system for developing automaticity with the facts.

This supplementary workbook is for children ages six and up, and has reproducible pages to give students an opportunity to learn the math facts. The addition and subtraction facts to 18 are taught in an original way-not just drill and practice, but by grouping and associating them with easy-to-learn methods and tricks. Each page was carefully designed; the facts are introduced with a trick and then those facts are practiced by trick name with previously learned facts, also identified by their trick name. After initial instruction, teachers/parents can assign workbook pages for class work or homework to give children practice and review. Not all students will need to do all of the pages. Cumulative practice pages include most, if not all, of the tricks taught to that point. The children will see that they can be successful in completing pages without counting on fingers or using a chart. This book will complement any mathematics curriculum, and is a perfect resource for parents, teachers, special education, and home school programs.Included in the book: Introduction, How to Use the Book, 232 workbook pages, Answer keys, Certificate of Mastery, Record-Keeping pages, Index

This volume emerges from a partnership between the American Federation of Teachers and the Learning Research and Development Center at the University of Pittsburgh. The partnership brought together researchers and expert teachers for intensive dialogue sessions focusing on what each community knows about effective mathematical learning and instruction. The chapters deal with the research on, and conceptual analysis of, specific arithmetic topics (addition, subtraction, multiplication, division, decimals, and fractions) or with overarching themes that pervade the early curriculum and constitute the links with the more advanced topics of mathematics (intuition, number sense, and estimation). Serving as a link between the communities of cognitive researchers and mathematics educators, the book capitalizes on the recent research successes of cognitive science and reviews the literature of the math education community as well.
