Math Mammoth Grade 5-B worktext (Light Blue Series) is the student worktext covering the second half of fifth grade math in the Math Mammoth curriculum. This is the 2023 edition.

The books starts out with chapter 6, where we study multiplying decimals by decimals, dividing decimals by decimals, and conversions between measuring units.

Chapter 7 covers the addition and subtraction of fractions, and chapter 8, the multiplication and division of fractions.

Chapter 9 is about geometry. Students learn to classify triangles and quadrilaterals, and study the concept of volume in the context of right rectangular prisms.

Features

- Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, not just learn "HOW" to do it.
- Concepts are often explained with visual models, followed by exercises using those models. These visual models can take the place of manipulatives for many children; however, it is very easy to add corresponding manipulatives to the lessons if so desired.
- The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much.
- Very little teacher preparation is required. :)
- The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material.
- After each chapter introduction, you will find a list of Internet links and resources (games, quizzes, animations, etc.) that can be used for fun, illustrations, and further practice.

Please note this book is spiral (coil) bound.

The first half of 5th grade math is covered in Math Mammoth Grade 5-A worktext (available separately at Lulu). Also available for grade 5 are the answer key book and a book containing cumulative reviews and chapter tests.

Lovely and comfortable
Color: Brown, Size: Mid Back
Well made and easy to put together. I bought 2 and found them both to be well worth the money. You can tell the quality is there vs. other chairs I’ve bought online before.

Smooth!
Color: Brown, Size: Mid Back, Color: Brown, Size: Mid Back
Good value and looks pretty good. Faux leather feels like Naugahyde. Should be durable since that's what boat seat are made of. Could use a bit more lumbar support, but overall quite comfortable. Wider than I expected (so it must be designed for us Americans.) Casters are fantastic. Far superior to traditional plastic casters. Because these are made of rubber, they are dead quiet and smoooooth rolling across the flooring. Took about 30 minutes to assemble. Lots of parts but the pictorial instructions were clear. I'd give it five stars, but I wish it had a bit more height adjustment. We'll see how it holds up, but so far I'm pretty pleased.

Very pleased with my purchase
Color: Brown, Size: Mid Back
Easy to put together - instructions are good - excellent quality and the chair is comfortable. Far from being flimsy it's a heavy chair which rolls perfectly as needed. You won't find that many good chairs (if any!) at this excellent price. As always the ultimate question is: would I buy it again? The answer is YES, definitively. Great purchase.

superb, worth 2x the pricez
Color: Brown, Size: High Back
While this may appear to be an average run of the mill copycat sort of generic office chair, it's actually very comfortable with perfect lumbar support. Looks great, and the leather (or leather equivalent) feels durable. This sucker will last me in my WFH setup for years I do not doubt. Save yourself a few hundred bucks getting this versus some "premium" office chair... I doubt you'll notice much if any difference.

22 year old gamer approved.
Color: Black, Size: Mid Back
So far so good!! I bought this chair for my gamer son, he sat the springs out of his last one, so this one making it this long has me very pleased. It was easy to put together, and the quality is pretty notable, especially the wheels, super smooth rolling. It was definitely worth what we paid for it, and he finds it very comfortable, providing plenty of back support, and a stable seat for hours of gaming.
