This cannot be pinpointed. And it won't be linear (they go backwards as well as forwards). But have a broad idea of their mathematical repertoire allows us to choose starting points...
So, target your instruction to developing mental representations.
Then, we must appreciate that almost all of what is considered 'practice' in classrooms is not.
...
@ashtonC94@blatherwick_sam@mathsteacher09 ...rather, what tends to happen in classrooms is surface level. We have moved away from what has always been known; the correct type of practice makes perfect.
Schools have largely stopped doing this because national bodies have promoted automaticity and fluency as the aim...
This proposes a challenge because there is absolutely nothing enjoyable about deliberate practice!
So, we need to continually demonstrate to pupils to benefits of determination...
@ashtonC94@blatherwick_sam@mathsteacher09 ...getting deliberate practice right in mathematics requires us to know the technical details of the mathematics at hand and to know the tried and tested techniques for best honing these - in other words, the teacher needs to know how to coach pupils in very specific ways...
Now, to your question, which is perhaps one about qualifications?
If so...
Suppose a pupil arrives in year 7 having gripped no maths at all (highly unlikely, but let's use the extreme example)...
@ashtonC94@blatherwick_sam@mathsteacher09 ...if you wish that pupil to get a Grade 4 at GCSE (I think that was the suggestion?), then all is well: it is absolutely possible and, actually, not particularly difficult if taken seriously.
So, we start afresh with them and build maths from the beginning.
That is perfectly doable. Take, for example, the 'KS2' you referred to (although there is no such thing really) and review the expectations. Compare to a foundation paper. You'll see that...
@ashtonC94@blatherwick_sam@mathsteacher09 ...someone who has gripped those stated areas of maths can comfortably complete a full foundation paper (you might have to throw in a bit of mean, median, mode and range, but not much else).
Getting from no maths to that maths in 5 years is more than achievable 👍
@ashtonC94@blatherwick_sam@mathsteacher09 ...the key to establishing, revising, strengthening and expanding mental representations is deliberate practice. And deliberate practice absolutely depends on consistently working as the very boundary of one's comfort zone.
This is why it is crucial to ignore KS2 or 3 etc...
@ashtonC94@blatherwick_sam@mathsteacher09 ...instead treat mathematics as a full domain and every pupil as an individual with some specific level of knowledge. Always target their learning at a 'just right' level of challenge to keep them in that zone.
This is why a goal of automaticity is harmful rather than helfpul...
@ashtonC94@blatherwick_sam@mathsteacher09 ...the teacher who is happy about the pupil who completes 30 questions correctly is the teacher who wonders why they can't do the same skill 12 months later.
30 ticks means they are completely in their comfort zone. No learning is happening. No long term memory is at play...
- Know that they can all learn well. They have identical potential
- Work hard on mental representations
- Ensure practice really is practice and not regurgitation
- Keep them at the bounds of comfort zone
In 5 years, they'll fly!

In the last 20 years, teacher training, inspection and PRM observations of classroom teachers have all become obsessed with the cult of pedagogy. They reward and promote the exquisite performer, for their card sorts, group work, 3-part lessons and active learning...
...yet they forget that pedagogy alone is useless. Teaching must be applied to something. We should not be interested in the who can “teach well”, but instead should reward those who can “teach mathematics well”...
The didactics of mathematics- the technical detail of what is to be taught - is vital. The effective mathematics teacher is the teacher who applies their pedagogy to ensure that all pupils grip ideas. This requires didactics, not mere performance...
Have being hearing lots of mastery myths this week (as I do every single week), so here are a few things that are most certainly not anything to do with mastery but are still being passed off as mastery...
Schemes of work stating, for example, what will be presented at pupils in Year 7, term 3, week 5, lesson 2 #notmastery
Unit tests used to label pupils with grades #notmastery
Anderson (1983); Fredrick, Walberg, and Rasher (1979); and Seifert and Beck (1984), find that pupils spend only about half their in-class time actually engaged in learning activities
There is a small positive relationship between allocated time (however measured) and pupil achievement.
There is a positive relationship between time-on-task and pupil achievement; this relationship is stronger than the allocated time-achievement relationship, but is still modest.
Following my recent chat about mastery learning and the ways that TIME is used in schools with @mrbartonmaths on his eponymous podcast, lots of people have being asking me to elaborate on what is known about how time is allocated in the classroom. So, here is a thread on time...
All human beings can learning well. But all human beings learn from different models, metaphors, examples and instruction. And, crucially, all human beings learn at different RATES.
In a mastery approach, TIME is the key variable.
Time is used in many different ways in schools. A summary of Cotton's Educational Time Factors follows...
