I find that kids have a tough time translating algebraic expressions to English and vice versa. Am I alone?
Yeah, didn't think so.
One of the things that I have been trying to focus on this year is to convey to students the universality of the things they are learning. For example, cause/effect in language arts becomes input/output in math. Conflict resolution is the same as problem solving. Language arts has expressions and sentences, so does math. Scientific method can compare to making a conjecture in geometry, testing it out and then using inductive logic to arrive at a conclusion (read: rule).
So what happens when you tell them to translate: the product of 3 and the sum of x and 2?
You get: 3x+2, right?
Not quite.
Well I figured we needed to develop a mashup of English and Mathanese; Mathglish, if you will. Here is what we came up with:
English to Mathanese:

Mathanese to English:
The key this time was to allow the mashup. I live in a rural area where the Spanish speaking population is very large. Many of my kids speak and understand Spanglish. I have never done it this way before and the kids nailed it.
How do you do it?
Update: Just did a quick check for understanding 2nd period and 26/28 kids circled the bases.
