Math Mammoth Grade 4-A Worktext (International Version) is the student worktext for the first half of grade 4 mathematics, and part of the Math Mammoth Grade 4 complete curriculum. This book covers addition, subtraction, patterns, graphs, large numbers and place value, multi-digit multiplication, time, and measuring.
The worktext contains both the necessary instruction and the problems and exercises (the 'text' and the 'work'; thus a "worktext"), and is for the most part self-teaching.

Please note this is a student worktext and does not contain the answers.

Features

* Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the maths, 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.
* There is a strong emphasis on mental maths and number sense.
* It requires very little teacher preparation, which is a big help to most parents. :)
* 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.
* For multiplication tables and division facts, you can use our online practice program (free).

The other parts of Math Mammoth Grade 4 (International Version) are: grade 4-B student worktext, grade 4 answer keys, and grade 4 tests and mixed revisions, all of which are available on Lulu.

Base isnt a charger, But otherwise its decent.
The overall quality of this product is high. It worked and funcioned as expected. My toddler hated it. He couldnt deal with the vibration even on the toddler steeing. It has 2 settings for different age ranges but you have to go through them every time you turn it on. This would have been better as a selector switch somewhere else that remained in place. The base is NOT A CHARGER. that was very dissapointing. Not only is the base NOT a charger, you cant even plug the toothbrush in and then let it sit in the charger. The should have just made the base...the charger. Plug that in and leave it and that way the tooth brush stays charged all the time. Overall other than the base being a dissapointment this isnt a terrible toothbrush. If your child is ok with the vibration they will probably love this.

Works well has plenty of pressure.
It is a great device, a bit awkward to use over a bowl sink, but with some minor adjustment of the nozzle, it works well. It appears to be as effective as most water picks and I like not having to fool with a hose, that can break.

Needed replacement, 2nd one works OK
The first one I received had a broken latching mechanism. Not a shipping issue, as the box was fine, it just wouldn't latch the attachments because the mechanism wouldn't come all the way out. After getting a replacement the 2nd one worked better. It has 3 settings for soft, normal, and pulse. For me, the normal put out the best force for clearing out bits. After washing with it for about 30 seconds though I still don't feel it cleans we well as real floss, or even a waterpik, but it does help after brushing. I will add it to my routine as it does help flush out some things, but it won't be replacing my flossing. It is sort of portable, in that can be packed away and holds a charge, but it's still pretty large and takes up a good amount of space in a toiletry bag. It's not bad, but not really outstanding either.

I like this better than my name brand unit
🔵 Features: The water pick boasts a generously sized reservoir, which is a standout feature. It also comes with a convenient USB charger, offers 3 speed settings (normal, soft, and pulse), and features quick and easy detachable heads. 🔵 Power: In terms of power, comparing it to my current unit revealed no noticeable differences in pressure or volume to the naked eye. Both units effortlessly deliver a stream of water up to 12 feet. 🔵 Heads: The water pick includes a plethora of heads, more than most people would likely need. Personally, I would have preferred a lifetime supply of the simple angled head picks, but the variety provided caters to all preferences. 🔵 Overall: After using it for a few days, I found that it performs admirably. When placed side by side with my old unit, I consistently reach for the 7AM2M unit, primarily due to its larger reservoir. In all other aspects, I find them comparable, and I wholeheartedly recommend this water pick to others.
