The two books (worktext part A and part B) deal with:the four operations with whole numbers
place value with large numbers and the judicious use of calculator
problem solving & simple equations
decimal arithmetic (all operations with decimals)
statistics and graphing
fraction arithmetic (all operations with fractions; fraction division is only dealt with in special cases)
geometry: review of angles, area, and perimeter; drawing circles; classifying triangles & quadrilaterals; volume of rectangular prisms
The fifth grade is time for fractions and decimals, in particular. In part 5-A, we study decimals in depth and with substantial detail. Students also deepen their understanding of whole numbers, learn much more problem solving, and get introduced to the calculator.
The year starts out with a study of whole numbers and their operations. Students get to review multi-digit multiplication and learn long division with two-digit divisors. We also review divisibility and factors from fourth grade, and study prime factorization.
In the second chapter, the focus is on large numbers and using a calculator. This is the first time a calculator is introduced in Math Mammoth complete curriculumthus far, all calculations have been done mentally, or with paper and pencil. I want students to learn to be critical in their use of the calculatoruse it with good judgment. Every exercise where calculator use is to be allowed is marked with a little calculator symbol.
The third chapter is about equations and problem solving. We study simple equations with the help of a balance and bar models. The main idea is to get students used to the idea of an equation and what it means to solve an equation. Students also do a fair amount of problem solving using the visual bar model.
The fourth chapter is about decimals and their operations. It is a long chapter because now is the time to learn decimal operations well. It is assumed that the student already has a solid foundation for decimal place value, as taught in Math Mammoth 4th grade curriculum. That is the true means of preventing common misconceptions, or students resorting to rote memorization of the decimal operations.
In chapter 5 we study graphing in a coordinate grid, line and bar graphs, and average and mode. Today's world has become increasingly complex, with lots of data in the media, so our children need a good grasp of graphs to be able to make sense of all that information.
Chapter 6 is about the addition and subtraction of fractionsanother focus topic for 5th grade, besides decimals. Students learn to add and subtract unlike fractions, using the technique of first converting them to equivalent like fractions.
In chapter 7, we study the multiplication and division of fractions (division only in special cases), relying first on visual models, and then proceeding to the abstract shortcuts.
Chapter 8 takes us to geometry, starting with a review of angles and polygons. From there, students will learn to draw circles, to classify triangles and quadrilaterals, and the concept of volume in the context of right rectangular prisms.

Great and balanced history of space exploration.
Format: Hardcover
An amazing coffee-table book that goes in depth telling the full history of space exploration, not leaving out the achievement of the Soviets and other pioneers. The print, photo quality and writing is top-notch with an unbeatable price. Just fantastic.

Interesting Material For The Space Inclined
Format: Hardcover
Okay, so I should start by saying that I am not a space exploration expert or really enthusiast. I am curious though. What this means is I don't have a lot of books on space exploration, and I haven't spent large amount of time looking at that kind of information. This review is from someone who is, well as I said, curious about it.
So let's kind of start with what this book covers, very early theory kind of things, lie Greek BCE space models all the way through possible future exploration and challenges with future development. It's very dry, very factual. It reminds me of kind of a textbook approach where it takes ideas like thee Space Lab, spy satellites (Corona Reconnaissance), and launch vehicles from Asia and just lays out what happened and key facts about the topic. These are not stories persay. They're not meant to grip someone not already interested and while I am sure someone deep into the topic might feel perfectly adequate to some, I wish I had more incentive to read it from start to end. Instead I largely jumped around looking at specific topics like the the First Flight, Columbia, which I had a basic foundation of information for already. This made it an easy read. In that same section, there is a topic called out about New Astronauts where women, diversity and non-military personnel like engineers and scientists became astronauts. For sections like these I wish there was... well more.
So it took me a really long time to go through the book because it consist of several topics that didn't draw me in and several that did but didn't provide as much information as I wanted. The book promises the history of the space exploration, from ancient time and to the future, and largely it delivers on the promise, in brief snippets, and maybe it the ambition of that massive amount of time that it left me feeling wanting about topics I already had interest in, like Mining the Solar system.
Think of this is a way to touch on nearly every topic, an tiny introduction to each one because very few topics have more than one or two pages covering it which means if you really want to know who is wants to go mine those 2 to 3k mineral rich asteroids, for what, and what the challenges are.. you'll need to find another book.
Finally, I'll touch on the pictures. Yes, you can find a lot of these online, probably even bigger ones, but have them all in one place. There are so many of them that you really could just thumb through the pages and see iconic as well as pleasantly surprising ones, and each one has a caption that gives some key details, like one that is the Boeing made shuttle main engine you can find at, well one of the museums of course! There was also a basic schematic for one of the engines which I was not expecting, and the same thing for a voyager probe.
It won't bee something I will ever browse again for casual reading, but for a space lover, this might be just thing they want to start with.
