Ask HN: Where to find good problem sets for elementary mathematics?
I’m coaching elementary math / CS to a few kids of age 9-12 from my extended family and I often struggle to find or invent relevant problems for them to train on. Do you have pointers to problem sets that I could use for this purpose?
Concrete examples of topics for which I could use problem sets:
computing angles in elementary geometry
fractions
solving linear equations
combinatorics
unit conversion weed through these search hits for something that fits your student bodies. Many might be above a lot of them, but a quick looks showed a few for the younger people.
