We took a triangular ruler outside, leveled the base and lined it up by eye with the top of the building. Then we measured the distance to the point where we were standing and the distance from the ground to the ruler.
I really wish education reduced the amount of rote learning involved and focused more on letting students explore and make mistakes with the educator as a guide.
Then one day we all went outside with our solar cookers and hot dogs and had a cookout. IIRC, there was a lot of variation among the cookers. Different reflectors were used (piece of aluminum sheet, bent and held by end brackets. Mylar film laminated to a wooden parabola "bed". One kid got adventurous and designed his with a vertical dog holder, and a circular parabola that was actually several different profiles stacked to "smear" the focal point along the vertical axis. I don't remember if it worked well or not)
I think we were meant to learn some sort of process engineering in addition to our respective subjects? Or just "teamwork", I guess.
In my experience, students are expected to memorize all sorts of equations without ever really being expected to understand why you're calculating the integral in the first place (even at decent universities). Obviously the risk with that is that you won't recognize any problem can be solved with integrals, no matter how concrete. Once I left the fancy tricks behind I felt like a fog lifted and it was actually really fun to see how integrals fit into both applied and abstract examples.
Going back to that simple explanation once people are a bit more experienced can make things click for a lot of people. Remaining people what they are dealing with and why can also help.
My class consisted of hour after hour of solving integrals of different types using all the different shortcuts, and the exams were largely the same. I feel like that time and effort could have been much better spent.
Aren't people who try to do this a running joke?
'Adam has five apples and seven buckets and must drive to Rapid City...'
People hate that stuff.
You can do a ton of cool stuff with maths, including calculating the movements for figures in a computer game, extrapolating the distance to the moon, etc.
And before someone claims I am beeing unrealistic: in my youth I worked with teens from socially complicated backgrounds and helped them to learn for their maths exams, exactly like this. These were kids that in bad moments would pull a knife on you or throw furniture out of the window. This was literally the only way to get them to start caring about the result of a mathematical formula and then they demanded to know more..
In fact I only understood why integrals were useful, when I started learning for the final exam.
This stuff can be really cool, but if even your teacher does as if it is the most boring and useless thing in the world, if even your teacher is unable to explain beforehand why you want to know this, how would you?
