chrisk120 :
That is VERY creative. i'd rather do it algebraically. But if I didn't know algebra, that is really cool reasoning.

Norman :
Too many people in the comments arguing that one way is faster or the other way is faster. Not enough people realizing that both are *doing the same thing*

Mr. Salazar :
Procedural vs conceptual. Many like to argue in favor for algebra with arguments of time/efficiency but when asked to explain, can not (in many cases). Bar modeling or strip diagrams are useful.

The second way is how my brain works. It was the reason I could get the right answer but couldn’t “show” my work.

He’s essentially saying you don’t even need to know algebra in theory

SKOLORADO :
I did it a bit differently. I knew that having 1/7 of the boys getting an A meant the total number of boys needed to be divisible by seven, and so would the girls by four. And because 116 is already divisible by four the number of boys had to be factors of four and seven. So by a very quick process of elimination (28 and 88 doesn’t work) got to 56 boys (8 with A’s) and 60 girls (15 with A’s).

The 7th markings being so good is the most impressive part of this

He's doing it the exact same way as "algebraic" but just visually

I love this so much I cannot even explain it.

Practical logic like this isn’t something that’s taught very well. Some people have an intuitive ability to do this offer rip and some people would really benefit from having these analogies explained and taught.

Orlando A Williams :
The algebraic way is faster IF YOU KNOW ALGEBRA is a point that many people seem to disregard.

You also know the amount of girls has to be divisible by 4 and boys divisible by 7

These are the kinds of teachers we need because not everyone thinks/solves problems the same way, but you can still get to the same (correct) answer.

This is really great. I think this is really useful for helping people be able to visualize what a word problem is actually describing.

Sherizati :
It's not about the expedience at which you find the answer. It's about understanding and visualizing what is being asked, and what the algebra represents.

I don’t need to know how to do this anymore but this made it so easy.

cupcakesncatastrophe :
I simply thought of it as the number of girls is divisible by 4, the number of boys is divisible by 7, so 4G + 7B = 116. Then we have the second equation of G + 7 = 23. That means G = 15, B = 8, or there are 60 girls and 56 boys.

I got lost when he said "and those two are 23, and those two are 23". What was his logic there?! It's 1am and I have a 4 month old and 2 others under 5 so excuse my brain for not working lol.

drawing the picture and with his slow methodical detailed explanation is the true answer. you are a fantastic teacher. some people will get the alternative faster some people will get the picture faster.
