Book Synopsis Math Mammoth Add & Subtract 2-A by : Maria Miller
Download or read book Math Mammoth Add & Subtract 2-A written by Maria Miller and published by . This book was released on 2024-04-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
Book Synopsis Strategies for Addition and Subtraction Facts Within 18 by : Maria Miller
Download or read book Strategies for Addition and Subtraction Facts Within 18 written by Maria Miller and published by . This book was released on 2015-12-30 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Math Mammoth Add & Subtract 2-B by : Maria Miller
Download or read book Math Mammoth Add & Subtract 2-B written by Maria Miller and published by . This book was released on 2024-04-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Math Mammoth Add & Subtract 2-B is a continuation to the book Math Mammoth Add & Subtract 2-A. The goal of this book is to study addition and subtraction within 0-100, both mentally and in columns, especially concentrating on regrouping in addition (carrying) and in subtraction (borrowing). Mental math is important because it builds number sense. This book includes many lessons that practice mental math. For example, the child practices adding and subtracting two-digit numbers when one of the numbers is a whole ten (such as 30 + 14 or 66 - 20). The students also learn to solve sums such as 36 + 8 or 45 + 9 with mental math (there is a regrouping), comparing them to the sums 6 + 8 and 5 + 9. Since 6 + 8 fills the first ten and is four more than the next ten, the sum 36 + 8 fills the next whole ten (40), and is four more than that, or 44. At the same time, students also learn to add two-digit numbers with regrouping. This is explained in detail with the help of visual models (base-ten blocks). You are welcome to use actual physical manipulatives, if you prefer. The main concept to understand is that 10 ones are regrouped to form a new ten, and this new ten is written using a little "1" in the tens column. After addition, the lessons focus on column subtraction, initially without regrouping and then with regrouping. The lesson Regrouping practices breaking down a ten into 10 ones. It is crucial that the child understands what happens here. Otherwise, they might end up only memorizing the procedure, and will probably at some point misremember how it was done. If you notice that the child does not understand the concept of regrouping, provide more practice with concrete manipulatives or visual exercises before proceeding. After learning regrouping, students practice mental subtraction in two separate lessons. One of them expounds on several methods for mental subtracting. The other is about Euclid's game-a fun game that also practices subtraction of two-digit numbers.
