1. Math Mammoth NewsHere's a short video I recently recorded covering the basics of Math Mammoth curriculum:
2. How does Math Mammoth teach math facts?
Math Mammoth uses a hybrid approach where the children are shown various strategies for math facts, but the curriculum also incorporates some drill.
For addition and subtraction facts, the main or foundational strategy is that of fact families. We don't just study one fact family here and there, but GROUPS of fact families. The reason for that is, it allows the child to see the PATTERNS and the structure in these facts. But – we also use drills. (See an example video here.)
There are also other strategies taught, such as doubles plus one, and the nine-trick.
For multiplication tables, the curriculum incorporates what I call a structured drill. This consists of first memorizing the skip-counting pattern, which are the answers, and then associating the different multiplications with the answers. At first the drilling is done within the structure of the table, and not randomly. From that we upgrade to random drilling.
The tables are also taught in a very specific order which lessens the overall memorization work. And there are videos that you can use for the multiplication table drills.
Based on the feedback I've gotten, this approach has proven to be quite effective.

4. Teaching word problems
1. Do you have a book on just teaching word problems?
No, I don't have a book focusing on word problems only... but some day we might put together one.
And I don't have a list of such keywords either. In fact, I don't believe in such an approach. Typically, if you teach that "this" word signals a certain operation, one can devise a wording where that same keyword signals something else.
For example, "more". Does it always signal that you should add? Consider this one:
Mickey has some toy cars, and Henry has 9, which is five more than what Mickey has.
Of course, most of you probably know that Math Mammoth books contain plenty of word problems. If a child has difficulties with them, I suggest, first of all, starting from the beginning, and secondly, asking children to draw or act out the word problems with objects, in grades 1-3 in particular. If the child continues have lots of difficulties, you might check if they have any problems with reading comprehension.
This article of mine can also help: The trouble with math word problems.
5. "How to Learn Math" (for students)"How to Learn Math (for students)" from Youcubed/Jo Boaler is now available for free from edX.
I have gone through this course several years ago and my daughters have as well; it is a good one. The goal is not so much to learn math per se, but to gain a different mindset towards math.
Here's the syllabus:

6. The equals sign creates troubleDid you know the humble equals sign (=) creates actually a lot of trouble?
I found it interesting that when students were asked to complete this:
4 + 3 + 2 = ( ) + 2Many students will incorrectly add everything on the left, put that in brackets, then proceed to add the final 2.
4 + 3 + 2 = (9) + 2 = 11The question really requires the following:
4 + 3 + 2 = (7) + 2 = 9------------------
Another problem is the "running equals" phenomenon, where people write things like
10 + 4 = 14 + 5 = 19 − 6 = 13If you take the first and the last expressions in the above "chain", you get 10 + 4 = 13.
According to the article, people in the US have much more of a problem with running equals than people in other countries, and I must say my experience agrees with that. The author of the article was thinking maybe it has to do with the fact children are allowed to use a calculator from a very young age. (Calculators often use "running equals" type of a processing.)
