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.

Only Made It Two Weeks
Color: Grey, Color: Grey
This toy easily became my Fig's favorite toy. The squeaker wasn't as annoying as it is in many other dog plushies. However, that's where the positives end. After the first week, there was a hole in the stitching on its neck. I sewed it up, but it obviously did not last. The squeaker went silent after a few more days. I bought it on March 28th, and it is now April 12th. It's just a rag, now. RIP little honey badger. You did well in your short life time.

Not 100% indestructible, but cute and worth the money
Color: Grey, Color: Grey
My dog absolutely love this little toy although when I looked up indestructible dog toys, this is one of the first things came up. I have to say it is not indestructible. I have not found one single dog ball or chew baby that is indestructible. My dog has found every which way to destroy them. It is now four days later and it’s still almost intact, but she has placed a hole in it. It does come with a squeaker, although the second day she already pulled it out it’s cute and it’s fun. Your cat could technically play with it if you had a cat and they wanted one quality wise, I would say it’s definitely close to indestructible, but it’s not completely indestructible and the colors were so fun.

It's not indestructible.
Color: Blue
Buyers beware, I have a jack russell, and I just got this item ten minutes ago, my dog ripped it up.It is not indestructible, it is a waste of money. My dog is very aggressive with his toys. So back to the drawing board...So I can't return this item because, it's ripped up and they're not gonna give me my money back... So do not buy this toy.

P.O.S.
Color: Grey, Color: Grey
Toy is not as advertised. It is NOT for aggressive chewers. It is NOT indestructible. It is NOT for medium to large dogs. I knew the moment I opened it that it would be demolished by my 24 pound Miniature Blue Heeler. And here we are 5 minutes after giving it to him, picking up pieces of cotton off of the floor. This should be marketed as a kids stuffed animal. In no way shape or form is this a chew toy unless you have an aging toothless two pound Chihuahua. It would have taken longer for my dog to chew up the $10 dollar bill I gave for this. 💩

Great for aggressive chewers
Color: Grey
Tuff toy, my yorkie has been trying to tare squeaker out for about 3 days, he works on the fur part but so far it stands up to his chewing, I have gone thru 3 other toys this week so glad thi one works! It lasted 8 days. They need to make whole toy out of material and put fur on top of the tuff material. Once he found out wetting the fur softens it he pulled the seam apart.
