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.

Aggressive chewer (terrier) approved!
Color: Blue Octopus
I would give five stars except for one small area. The back seam was too easy to access to get the squeaker out (literally under half an hour of him playing). ***BUT*** the legs are SO strong and can be used for tug of war and they are crinkly and he loves it. Highly recommend!

Not bad, wish it was more durable

GREAT FOR MY LITTLE ADOPTED DOG!
Color: 6 pack
These little soft dog toys are wonderful for small to medium sized dogs. I recently rescued a dog who had never seen a toy, nor did she know how to play with them and these are perfect. She is a 13 pound half Chihuahua/terrier mix, and she loves to play with these little toys. They’re cute to me and she likes them so that makes me happy.

Cute but not durable
Color: Blue Octopus, Color: Blue Octopus
My dog LOVES the toy and was so excited to get it. It is so cute…but not durable like advertised. My chewer was able to rip a hole by the evening we received it. We like it…just not excited for the clean up
