Primary Math Book 2A teaches numbers, comparing, and place value to 100, addition and subtraction with/without renaming, measuring length in meters, centimeters, yards, feet and inches, measuring weight in kilograms, grams, pounds, ounces, multiplication and dividing by 2 and 3.

The Primary Mathematics U.S. Edition series of elementary math textbooks and workbooks is meant to be part of a system of learning in which adult supervision and independent practice go hand in hand. The main feature of this series is the use of the Concrete to Pictorial to Abstract approach. Students are provided with the necessary learning experiences beginning with the concrete and pictorial stages, followed by the abstract stage to enable them to learn mathematics meaningfully. This approach encourages active thinking process, communication of mathematical ideas and problem solving, which helps develop the foundation students will need for more advanced mathematics.

Practice exercises are designed to provide the students with further practice after they have done the relevant workbook exercises. Review exercises are provided for cumulative reviews of concepts and skills. All the practice exercises and review exercises are optional exercises.

The color patch is used to invite active participation from the students and to facilitate oral discussion. The students are advised not to write on the color patches.

Above extract from Preface of Primary Mathematics U.S. Edition (reproduced with the permission of the publishers).

The textbooks contain the learning tasks for students to do under adult supervision and interaction, along with practice and review problems. They are meant to be non-consumable and to be used along with the Primary Mathematics Workbooks.

Answers or answer keys for Primary Mathematics U.S. Edition textbooks and workbooks are found in the teacher's guides and home instructor's guides. Answer keys booklets are also available - one for Primary 1-3 and one for Primary 4-6.

All 3 dogs, 3 different sizes and ages love it! Can’t go wrong!
Size: Medium, Style: Bristle Bone
Great! Super great! When you HAVE TO GET THEM OUT OF YOUR HAIR! This toy is durable even without the beef flavored insert! I have a Border Collie who has too much energy and an Aussie who can’t sit still and a small stray who is constantly figuring out a way to steal these from the other two! Safe, effective and actually cleans their teeth! This might well be my first Amazon review because this toy deserves it!

Bully approved
If he wants something to gnaw on he will sit with it but he doesn't really play with it. Which is probably the point. It's lasted. The ends are the most chewed. Overall great for a chewer!

Surprisingly Durable
Color: Green
Our dog is an aggressive chewer. She has destroyed other toys meant for "aggressive chewers" in less that 6 hours. This toy has lasted 17 days and it's still going. It does have areas were the seam has given way and a very small amount of stuffing has come out. She has "killed" the squeaker. But the toy is still usable. We just played Tug of War this morning. It will not last forever. It is showing it's "age". But the durability is there. I am ordering more.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.
