So an article has come out in the UK about calculator use in primary schools. They are close to banning them in primary schools since they have dropped in PIMMS (?) rankings in maths. I agree that more students are struggling with math due to over relying on the calculator. I even think that I fell into some of that reliance on the technology. It will be interesting to see if it actually is implemented in the schools and what the results will be.
