Math Mammoth Contest

Explain WHICH book or product interests you most (see the website). Then explain in several sentences the reasons and factors that keep you from buying it at this time. In other words, give your "excuses" for not buying. You can explain how much you perhaps love your current math curriculum, cite economics, and so on. Just let your fingers fly on the keyboard!

Math Mammoth is having a contest for books from her website.

This here be my entry. :)

What would I like to get should I have an opportunity to do so?
Math Mammoth Clock
is a worktext that covers telling time and reading the clock, telling time intervals, and understanding the calendar. It is suitable for grades 1, 2, and 3.
Why? Because telling time is important. :) And I figure this book will have some hints for helping my buggy learn to tell time that I might not think of.

Math Mammoth Canadian Money
is a worktext that covers money-related topics usually encountered during grades 1-3, using the coins and bills of Canada. The book contains both textbook explanations and exercises, and is designed to be very easy to teach from, requiring very little teacher preparation (you do need to find some practice coins before the lessons).
Why? A book that uses Canadian money! so many are just USA only. So I think this is cool.

And last but not least Math Mammoth Introduction to Fractions
contains fraction-related material suitable for approximately grades 2-4. This material does not include division or multiplication of fractions, nor adding unlike fractions. The lessons are mostly simple, introductory lessons to various fraction topics.
why? simply because the idea of teaching fractions seems a bit beyond my thinking today. I know my buggy is only 3 and fractions is not something he'll be learning yet....but it's good to be prepared. :)
