Primary Math Textbook 1B teaches comparing numbers, picture graphs, counting, addition, and subtraction to 100, multiplication, halves, quarters, telling time, money and more.

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.

Long lasting dog treat
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
My dog absolutely loved this stuffed shin bone—it kept her occupied way longer than most treats, which is always a win. It’s a great option when you need something that will actually hold their attention. What I Loved:    •   Long-lasting chew compared to typical treats    •   The stuffing inside keeps dogs interested and engaged    •   Helps with boredom and keeps them busy    •   Once finished, the bone can be reused with other fillings One Small Con:    •   It can get a little messy depending on how your dog chews, so it’s best to give it in an easy-to-clean area Who It’s Best For: Perfect for medium to strong chewers or dogs that need something to keep them occupied for a while. Final Verdict: This is a great value and a go-to for keeping dogs entertained. I’d definitely recommend it if you’re looking for a longer-lasting treat that your dog will actually stick with! 🐾

🦴 The Ultimate Distraction: A Must-Have for Power Chewers!
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
Finding a chew toy that can withstand my 70-pound "House Hippo" (an expert-level destructor) for more than ten minutes felt impossible, until we discovered these stuffed shin bones. These treats are an absolute game-changer for long-lasting entertainment, durability, and distraction. Exceptional Durability and Value: The bone itself is thick, natural, and surprisingly sturdy. Unlike processed chews that crumble or get demolished instantly, these last for days of chewing. The value is tremendous because they provide two phases of entertainment: first, the intense effort of licking out the filling, and second, the satisfying work of chewing the bone itself afterward. Irresistible Appeal (Peanut Butter/Cheese Filling): The filling is the secret weapon! My dog goes absolutely wild for the flavor. The filling is firmly packed inside, which means he has to spend a significant amount of time actively working to get every last bit. This intense focus buys me hours of peace and quiet, which is invaluable. On top of that, they offer good nutrition! Less Mess, More Fun: I appreciate that these bones are relatively neat. They don't leave greasy residue all over the carpet like some marrow bones, and the durable exterior means minimal splintering (though, as with any bone, supervision is required). They satisfy my dog's natural chewing instinct while promoting dental health by scraping against his teeth as he works the chew. Final Verdict: If you have an aggressive chewer who needs a serious, long-lasting treat that is both entertaining and structurally sound, look no further. These stuffed bones deliver on their promise and are now a staple in our dog treat rotation!

Still Going Strong Months Later
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
These stuffed chew bones have been amazing for my dogs. Even months later, they’re still happily chewing on them, and that says a lot since they’re aggressive chewers. The bacon and cheese filling keeps them interested, and the bones themselves are durable enough to handle their chewing without falling apart. After all this time, the chews are still holding up and my dogs love them every time. They keep my dogs busy, help with dental care, and are definitely worth having on hand for large dogs who love to chew. Durable, tasty, and long-lasting—can’t ask for more.

Long lasting
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
These are the longest lasting bones I have ever purchased. But if you don't want a heavy bone that makes noise when dropped this is not for you. They go sliding across my floor as they are being tossed around and played with. But they love them and they have lasted for months. I am glad they are not as expensive as others. To many things are over priced. Dogs love them.

Arrived on time and as described
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
It is perfect for my 120 lb dog. He did give up after 6 hours of trying to get the “stuffing” out. The bone held up to his chewing. He loved it!
