It was SMP maths my primary school used, basically same principle as you describe..grab a card out of a box and work your way through on your tod...no learning of principles whatsoever. A fecking horrendous way to try and teach maths.
What did SMP stand for? When I was nineteen I had cause to go back, to seek help with some more advanced maths, and was told that KMP had been replaced by SMP.
At my primary school we had Maths textbooks from SPMG - the Scottish Primary Mathematics Group. Pretty good as I remember.
