PDF + Softcover B&W

Math Mammoth Addition 1 is a self-explanatory worktext, dealing with the concept of addition and addition facts within 0-10 (in few occasions numbers between 10 and 20 are used). The book is suitable for kindergarten and first grade.

The PDF version of this book is enabled for annotation. This means that if you prefer, your student can fill it in on the computer, using the typewriter and drawing tools in Adobe Reader version 9 or greater.

The book starts out with very easy addition problems within 0-5, using pictures. If the student does not yet know the symbols + and = , you can introduce them first orally. In other words, use blocks or rocks and make addition problems where you use both kinds of wordings: “Three blocks and four blocks makes seven blocks. Three blocks PLUS four blocks EQUALS seven blocks.” Play like that until the child can use the words PLUS and EQUALS in his/her own speech. This will make it easier for him/her to use the written symbols.

Soon the lessons start including “missing addend” problems. We first use pictures, and gradually get to the abstract 1 + __ = 5 with symbols only. Keep in mind that children may confuse this problem with
1 + 5 = __. You can word these problems like this: “1 and how many more makes 5?” You can MODEL them by drawing: First draw 1 ball. Tell the child that we need to have a total of 5 balls. He is to draw more until there are five balls. In the missing addend problem, however many balls the child has to draw is the number that goes on the empty line. So, first there is one ball, then we need to add (draw) some more to make 5. But how many more were drawn?

After that, the book contains many lessons called Sums with... whose goal is to help the child memorize addition facts.

My approach to memorization is many-fold:

  1. Structured drill, such as you see in the lessons Sums with 5, Sums with 6, and so on. This is not random drill, because you will start it by showing the pattern or the structure in the facts. This will help the student to tie the addition facts in with a context and help him understand the facts more on a conceptual level, instead of merely memorizing them at random. In sums with 5, the child learns the number combinations that add up to 5: 0 & 5, 1 & 4, and 2 & 3. This understanding is the basis for the drills.

  2. Using addition facts in games, in math problems, everyday life, or anywhere else. Games are especially useful because they help children like mathematics.

  3. Random drilling may also be used as a tool among others.

  4. Memory helps such as silly mnemonics or writing math facts on a poster and hanging it on the wall. These are not needful for all children.

However, keep in mind that children will need LOTS of opportunities to add numbers to actually memorize the facts, so the memorization may not totally occur as your child works through this book. These same addition facts are further studied and used in the Math Mammoth Subtraction 1 book, and in all later math work since they are constantly used. At the latest, your child should memorize addition facts during second grade.

Quotes About This Product

Math is actually fun and he [my son] is remembering so much more than he did with the other systems we used.

The difference in his math skills is amazing. He is able to tell me the answers from oral drills without even stopping coloring for all his sums up to 5. Your worksheets just show him the ideas in a way I wasn't able to explain and without all the storylines that Calvert and Singapore use.

I have struggled with teaching my son his math facts. He is dyslexic which makes it much more problematic for him. I was really looking for a math book to teach math families in a fun way vs just flash cards all the time. This was the answer, he loves [...]

Math mammoth involves more writing of numbers than I had thought so I will wait a bit before using this product with my 4.5 year old. I have used some of the activities as inspiration for manipulative based activities, which he enjoys. [...]

I bought this to help my daughter learn her addition facts. Our current math curriculum used the flashcard method, which was not working for us. I have been SO PLEASED. In just one week, my daughter has memorized more math facts than she did in a year [...]

I bought this book for my 5yo daughter and I am very pleased with it! The teaching style reminds me of Singapore Math. Another reviewer mentioned the space to write answers in was too small; My kids didn't have any trouble with this (and they have poor [...]

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
