Ok, so I think, having looked at these I do now understand the relationship between them. I think the work you are planning will effectively join the ESIFC on the left across the void to the ATLs on the right. Is that correct?
If so I think my next step would be to look at the curriculum plans across the school and see where the skills can best be introduced and reinforced across MYP. This would create another 3 maps that sit behind this and show its practical implementation in years 7, 8 and 9 (we only run the 3 year MYP) Is that what you are planning?
I think that I may need to have done that before I am able to get the staff on board. Clearly, I would only be able to suggest ideas and any detailed lesson documents or workbooks would be my next step when teachers have seen the benefit and we can collaborate.
