Dimensions Math® PreK-5 series features the progression, rigor, and pacing that define Singapore math. Throughout the series, five characters offer students suggestions on how to think about problems. They remind students of strategies they’ve learned and point out important information that encourages them to come up with their own solutions.

Textbook lessons begin with a task that allows students to apply their previous knowledge and learn through discussion. Once students have mastered a concept with the use of concrete and pictorial aids, they are ready to take on more abstract mathematical problem sets. They reach fluency by collecting various strategies along the way and applying them to new problems. Word problems give students a sense of math in real-world contexts. 

Workbooks offer independent practice that follows a careful progression of exercise variation. Each textbook lesson includes a corresponding workbook exercise that starts with pictorial representation and progresses to more challenging abstract problems. Workbooks for PreK-2 are perforated. 

Teacher’s Guides include lesson plans, mathematical background, games, helpful suggestions, and comprehensive resources for daily lessons. Lessons are laid out clearly and activities are designed for the whole class, small groups, and extension.

Textbooks and Workbooks do not include answer keys. Answers are in Teacher's Guides.

Aggressive chewer approved
Size: Large, Number of Items: 1, Size: Large, Number of Items: 1
Got this to help amuse my 90lb GSD while I was out of town for a month. He gets one meal a day in it, and really enjoys the work. It’s easy, not a puzzle, no frustration, just a “job.” He chewed on the yellow top pretty aggressively while I was gone, and it still works fine. This is a dog that destroys even the most durable chew toys in minutes to hours when he’s anxious, and I imagine he experienced some anxiety while I was gone especially during periods when he was alone. So, I’m quite pleased with the durability. This will definitely stay in the meal service rotation and I will replace it if necessary. One thing to note: the fill hole is pretty small. His kibble is small enough that one might think it would easily pour right in, but no. At some point I’ll get annoyed enough to pull out my drill and make that hole larger.

My dog loves it
Color: 1 PC-Beef-Red, Color: 1 PC-Beef-Red
The bone arrived today and my dog loves it. He is a very aggressive chewer and destroyed almost all his toys so far, even toys that were advertised for aggressive chewers unfortunately didn't held out long, the longest so far was a stuffy we couldn't find anymore and that one lasted him a few weeks but everything else lasted him an hour up to a few days max, even bones don't last him long so we have our hopes set on this bone to satisfy his chewing needs. I will update my review later on sturdiness, since we just got it and I can't review that yet but so far he loves it he has been chewing on it non stop, he already managed to get very small pieces of as shown in picture but with a regular bone he would've already been much much further. The bone is only 10 bucks so the value for money you get based on my experience so far is amazing! But also for this I will come back later to touch upon more. The size is good, our boy is a medium sized dog and this bone was advertised for medium to large size dogs and I thinks the size is just right for our boy . And there is definitely a beef flavor on it you can smell it but it doesn't smell bad it's a nice smell and not very strong but when he is chewing on it you smell it. I would based on my experience so far definitely recommend this bone but also on this I will touch back upon later if it's worth it in the long run. So far a very happy dog and owners here. Edit on May 8th (original review was on March 11th) He still hasn't managed to destroy it it's the first (cgew)toy he hasn't managed to destroy yet which is very impressive since he managed to destroy the even most toughest things we got for him in a week tops and bones within 1, 2 days tops, so we are very happy and pleased with this bone and will definitely get more later. He still enjoys chewing on it and leaves our things mostly alone for some reason he just likes stealing my things and chew on it lol. So 2 months later still stand by recommending this when your dog loves to chew and destroys everything he puts his mouth on.

Extremely durable, dogs love them
Color: 2 PC-Beef-Red, Color: 2 PC-Beef-Red
I was looking for the toughest and most durable dog chew bone I could find and this is it. I have bought multiple other brands that claim to be very durable and tough for a very long time and this is the one for sure. The shower has described this phone accurately and it truly does last. I purchased this bone about 2 months ago. As you see from the photos attached, this is a very well made chew bone and my aggressive pitbulls can't tear it apart do they try. They never get tired of it and chewing it every single day for hours on and keeping them very occupied. I have two bones and three pitbulls that chew on it every day. It is so adorable and has an awesome flavor to it which I think entices them even more to want to chew on it. The durability and Lasting power is amazing to me with these tough chewers. I highly recommend this product to everyone out there. I will say only one negative and that is that the middle wraparound piece they were able to pull off but that is not a big deal because there is plenty of bone which was under that cover in the middle of the bone. There's a few mauled chips missing from the ends but the life of this bone is obviously going to be a long time which really surprised me. Give it a shot if you have heavy duty chewers and you will find how awesome this phone really is and it's durability and strength our second to none in my opinion.

My dog loves it.
Color: 1 PC-Beef-Red
My dog is a super aggressive chewer when it comes to toys. Anything that is soft he rips apart. This one has a wonderful squeaky sound that makes him happy and he enjoys the smell of it. This is a very strong material and definitely worth the price.
