I am looking at purchasing the Abacus maths scheme and have got a free trial at the moment. I've had a look and really like the planning and resources - we are looking at mixing this with White Rose mastery questioning to bulk it up a little. Is anyone using the Abacus maths scheme and how are you finding it? What other schemes are you mixing it with (if any)? How do you use the extra resources (fluency fitness, problem solving etc) to structure your lessons? I'm surprised to find mostly negative reviews around Abacus an mostly it's due to the lack of mastery questioning but it seems to give a good base of fluency to build upon.
