And the bar models themselves are great for multi-step problems and a great tool to analyze the problem and draw it visually. They are great as a step towards simple algebraic problems.

How is this emphasis on understanding? Where do the students even evaluate that it is a comparison before they start the model? How is the names the most important part of the problem? I could rewrite the problem with different names, different theme, and it is solved in exactly the same way. And...

Guess and check? That is not how you should solve this problem. That is silly. These bar models are not about guessing.

If spending time drawing pictures about a single math fact is math, then this sounds an awful lot like Investigations where they had to draw squirrels in rows and columns to show a multiplication fact. So did they add by counting? You are supposed to add by making a ten. I guess you can modify an...

There is a "Singapore Math Way" to organize a box. Cool. Maybe there is a "Singapore Math Way" to organize my house.

This is the way they learn it the third grade with the Primary Mathematics. So by fifth grade they can divide easily. But I did it this way with my children even without the Singapore math when I homeschooled the older ones before I used the Primary Mathematics with the youngest one. I just used ...

Nice that it all works out with exactly twice as many and all the blocs end up equal sized.. It looks like the problem was made up to fit making a model.

Better to start with the after information. Then you don't even need the before model.
