Blackline Masters for 2A

Click here to view samples of Dimensions Math® Teacher's Guide 2A.

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.

My Dogs' Absolute Favorite Chew: Tough, Flavorful, and a Lifesaver for Boredom!
What sets the Benebone Wishbone apart isn't just its durability—though that's impressive enough—it's the thoughtful design that caters to how dogs actually play and chew. Crafted from super-tough nylon infused with real bacon flavor (not some artificial nonsense that fades after one gnaw), this wishbone-shaped toy is ergonomically curved for easy gripping with paws or mouth, making it perfect for aggressive chewers who like to toss, carry, and battle it around. The three prongs give them multiple angles to attack, which keeps them engaged for hours without getting bored. For my Goldendoodles and Golden Retriever, who are all large-breed goofballs with endless energy, the large size (about 7.5 inches long) is spot-on—not too big to intimidate, but substantial enough to withstand their enthusiastic chomping. We've had ours for over two months now, and while it's showing some honorable battle scars (tiny grooves from their teeth, which actually make it easier for them to grip), it's nowhere near splintering or breaking. Compare that to the Nylabones we've tried, which either splintered too quickly or lacked any real appeal—these Benebones win hands down every time.Flavor is where this toy really shines, though. That real bacon infusion isn't just a gimmick; it's embedded throughout the nylon, so even as they chew deeper, the savory scent and taste keep coming. The more food-motivated Goldendoodle goes absolutely feral for it—drool flying as he parades it around the living room like a trophy, grumbling possessively if the others get too close. The female Goldendoodle prefers a more playful approach, flinging it across the room before pouncing back in for wrestling matches that leave her curls even more disheveled, while the Golden Retriever settles on the rug for long, focused sessions that help him unwind after fetch marathons. It's hilarious to watch them "fight" over it (in the gentlest, most sibling-rivalry way), but what's even better is how it redirects their energy. No more shredded couch cushions or nipped at ankles during zoomies—these bones have cut down on destructive behavior by at least 80%, giving me more time to relax and less time playing fetch with toy remnants.Safety and quality are top-notch too, which is crucial when you're dealing with heavy chewers. Made in the USA with non-toxic materials, it's free from BPA, phthalates, and all that sketchy stuff you worry about with imported plastics. The company even encourages responsible use: supervise play, especially for puppies or super-aggressive types, and replace when the ends wear down (though ours are still going strong). At this price point for a toy that lasts weeks instead of days, it's an absolute steal—I've already ordered backups in peanut butter flavor to rotate in and keep things fresh.If your dogs are anything like mine—energetic, mouthy, and in constant need of occupation—this Benebone Wishbone will be a game-changer. It's not just a chew toy; it's a boredom buster, a dental helper (those ridges get the tartar going), and a source of pure joy for your furry family members. My dogs love these bones more than their walks some days, and that's saying something! Five stars all the way—highly recommend grabbing one (or three) before your next Amazon order. Your sanity (and your furniture) will thank you.

Truly Durable - No Joke, These Actually Last
I purchase these for the rescue I support, and they live up to their “durable” claim - no joke, these truly last. Durability: These are genuinely built for aggressive chewers. While the edges do eventually get rough with heavy use, the fact that they last a while with determined chewers is impressive. Most toys don’t make it that far. Design: The wishbone shape gives dogs multiple angles to chew from, which keeps them engaged longer. The ergonomic design works well for powerful chewers. Made in USA: Knowing these are made in the USA gives me confidence in their quality and safety, whether for rescue dogs or personal use. Flavor: The real bacon flavor keeps dogs interested and coming back to the toy repeatedly. Pros: ∙ Truly durable - actually lasts ∙ Made in USA ∙ Real bacon flavor dogs love ∙ Wishbone shape for multiple grip points ∙ Perfect for aggressive chewers ∙ Edges get rough eventually but toy holds up ∙ Rescue regularly uses these ∙ Better longevity than most chew toys Bottom Line: When a chew toy genuinely lasts with aggressive chewers, that’s noteworthy. Yes, the edges get rough with extensive use, but the toy itself holds together far longer than most. Excellent for rescues, shelters, or anyone with power-chewing dogs. Highly recommended!

Great Bone for aggressive chewers but watch the wear & tear
I’m extremely happy I found Benebone Bacon Flavor Large Wishbone for my puppy who is an aggressive chewer. As the packaging reads this is a durable nylon. My puppy chewed the bone down to what you see in the picture within 3 days. It’s easy for him to handle. He loves the bacon flavor. He immediately took to it as soon as I gave it to him & off he went to work. I did check with my Veterinarian first to inquire if this was a safe bone & she assured me it was. She did advise to be aware of the wear & tear on the bone & toss when I felt it was time. I honestly wouldn’t of known when. I’m happy I took the time to read the inside of the packaging this bone came in. It referred me to the benebone website which showed pictures of bones-which I attached- that reflect the wear & tear & when it’s time to toss. There are the 3 categories of “Light Wear,” Moderate Wear“ & “Heavy Wear.” You’ll see the written description next to each. This I found very helpful, therefore I wanted to include it in my review, in hope of helping you. By the looks of my current bone it’s in between moderate & heavy wear. The large is costly, I feel, but it 100% occupies my puppy. It’s his favorite “toy.” I’ve only had small shavings come off since he’s chewed it. Nothing major to clean off the couch where he lays. Stuffed toys are a thing of the past now. I’ll continue to buy once it’s time to toss this bone because he loves it so much. I also love that Benebone is Made in the U.S.A.! I definitely recommend! A heads up! If you click on their store on the main page of this bone you’ll find other shapes of the nylon bone as this one. This Benebone won’t disappoint. Take the time to read the packaging. It’s informative & cool!
