The portion in which the young student talks about Singapore Math books is very brief, but its good to know that its not just the adults, but the students themselves who find our textbooks helpful. The state of Math ability in the US is at a crisis- with an entire generation of youngsters fed on “fuzzy math”- aka TERC investigations, supposedly a new way of teaching math where the kids learn to discover principles on their own. I hope we never go down that road with newer teachers pushing for more “creative” classes.
Some things just need to be drilled and then later understood.
