Math Mammoth Clock


Math Mammoth Clock is a worktext that covers telling time and reading the clock, telling time intervals, and understanding the calendar.

The book contains both textbook explanations and exercises, and is designed to be very easy to teach from, requiring very little teacher preparation.

Math Mammoth Clock covers reading the clock, figuring out simple time intervals, and using the calendar, all in one book. The topics progress starting from the first grade level to the third grade level. Therefore, you also can let your child work the pages of this book in different time periods, and not go through it all at once, depending on your child's current level.

The lessons are divided to the grade-levels this way: reading the clock to the half-hour is first grade material; reading the clock to the five-minute intervals is second grade; and reading the clock to the minute is third grade level. I realize this is somewhat arbitrary, and there is no need to follow it exactly but I want to explain it so you can keep it in mind that the material in this book does get more difficult towards the end.

You will need a practice clock, such as an alarm clock, where the child can turn the clock hands. Reading the clock is a skill that will be used in everyday situations, so this topic (fortunately) is one that children also learn by experience, and do not easily forget once learned.

The PDF file for this product 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 Acrobat Reader version 9 or greater.

I was skeptical, but I'd heard so many rave reviews that I decided to test this program. My daughter has struggled with clocks, and it's been a week of about a page a day, and she's totally able to tell time now! I'm convinced! [...]

My daughter wanted to learn how to tell time and I decided to buy this instead of paying a similar price for something on TeachersPayTeachers. I think that I made a good choice as this gave me much more content and structure for the price. [...]

I love this curriculum because it allows my child to work on a specific topic until they get it down. It builds in easy steps. Sometimes the directions are a little confusing for the child (& for me) but we always figure it out. She just demonstrat [...]

I'll be using this as a "bridge" activity for my 5 year old over the summer. It looks great! The clock pictures are clear and large enough for her handwriting. It takes you through each step of learning to tell time and the parent/teacher gui [...]

This program has been a wonderful supplement to our Math-U-See Alpha program. MUS does not spend a lot of time on clock-work so I print off a page of the Math Mammoth Clock each day and staple it to her daily MUS worksheet. [...]

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.
