Learning algebra lets students apply “lower math”. You may not use algebra at starbucks but the extra application of “lower math” will help you make change for a dollar.
Learning algebra teaches students “how to learn”. Too many students (and then employees) don’t know how to learn. Students should be stretched in a number of areas, some of them “hard” for every student (math, reading comprehension, professional writing, science, etc). They may end up in a job where those areas are used. In most cases they will not use it but will be able to learn whatever they need for the career they choose.
We should bring back vocational training (like metal-shop). If some students and their parents really want I’m ok with them skipping algebra and taking fast-food-shop. At least learn to make change for a dollar and keep your hand out of that bubbling liquid the fries go in and maybe practice speaking English and being polite.
Must be able to make change in one’s head first, before manipulating multiple variables.
