Not sure this makes sense pedagogically. I would challenge you to try this in a classroom of average middle schoolers and see how it goes. I don't think you grasp the difficulties here.
- _aavaa_ 4y agoNot sure why you think it doesn't make sense pedagogically. Counting and numbers are taught before addition. Then addition is "proved" in terms of those. Then multiplication is "proved" using addition. One building on the next.
- adamsmith143 4y agoThe proof for 1+1=2 is something like 150+ pages. We don't give that to kindergarten kids do we.
- _aavaa_ 4y agoHence the use "prove" rather than prove. But the length of the real proof is beside the point. We teach them about 1 and 2 before going to 1+1=2. And when we do go to 1+1=2, we show it to them using objects and counting. We don't simply tell "here's the function for addition, just put numbers into to to solve problems".
