Blackline Masters for PKB

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

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.

Great for big dogs
Size: Medium, Number of Items: 1
Our pup is now 15 months old (nearly 110 lb and still growing). We got this ball when he was 3 or 4 months old. GOODS - - Our pup fetches with extreme drive, and the rope helps him quickly snatch the ball off the ground (versus a tennis ball, in which we are worried he will go head over heels at times) - Our pup also loves to play fetch in the water, and this ball floats great and again, the rope gives another point to bite onto - The yellow color is easy to see, even in grass - Our pup typically fetches the ball, and leaves the rope mostly out of his mouth. So, throwing the ball doesn't result in saliva-covered hands - It's pretty easy to throw the ball 50', and possible to throw it 100' - It doesn't roll/bounce, so if you are for example playing fetch on your front lawn and are concerned with a tennis ball rolling into the street, this one alleviates that issue - Our pup is spoiled and has several balls. This is absolutely his go to ball. We have woken up in the morning before to see him standing next to the bed with the ball in his mouth, asking us to get up and play. BADS - - Occasionally when he goes to fetch it, he will step on the rope as he tries to pull up on the ball. - We have gotten this ball stuck in trees multiple times. In fact, there is one stuck on the roof of our church from playing fetch on the lawn there. :-/ Not a fault of the ball, but if you start whipping it around like nunchucks, it might not go where you want. - The near max you can through this ball is 100'. And since it doesn't roll/bounce, throw distance is throttled. We often play fetch in a local baseball field, and have no issue wearing him out with this ball. However, if you are planning on throwing a ball the distance of half a football field, you might want to consider something else. SIZE - - We purchased both the medium and the large. Even though our pup is huge and can fit a soccer ball in his mouth, he still prefers the medium. It's easier for him to get in his mouth and breath while running back. The medium is the size of an orange, whereas the large is the size of a grapefruit. DURABILITY - - We have gone through about 4 of these balls, BUT this is because we lost 3 of them. We believe he dropped one out of the car window while we were driving, one is on the roof of our church, and I forget about the other one. On the first one we had, the stitching behind the black tape was down to a few threads after about 5 months. Given duration we use these balls (every day) and the joy he gets from them, I feel the durability is good for the price. - We do play tug with the ball at times, and no issues there Enjoy!

Good but better options out there.
Good ball, but is a cheaper version of the Foamster sold online. The rope is cheap and comes apart, and can be abrasive to a dogs mouth. The Foamster uses a higher quality ball and are more durable and use grippy biothane straps rather than cheap rope. They are also made to order in the USA with lots of fun colors. Worth the extra money if your dog likes these balls.

Fun toy for fetch
Size: Medium, Number of Items: 1
Daisy loves this toy. I found it from her dog trainer, and it makes rewarding her with a quick tug of war and fetch really easy. Also it’s shockingly durable. It looks like foam, but she has not destroyed this one.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.
