Revision task - The 12 days of Christmas

An idea I found on TES but I needed slightly harder question (and a rhyme…)
Built along the 12 day of Christmas song:
HIGHER:
on the first day of Christmas… equations
on day 2: equations and standard form
on day 3: equations and standard form… and angles
on day 4: … and surds
on day 5: … and factorise
on day 6: … and ratio
on day 7: … and indices (getting harder)
on day 8: … and product of prime factors
on day 9: … and Circle theorems
on day 10: … and long multiplications
on day 11: … and simultaneous equations
on day 12: … and estimate (calculations)

FOUNDATION
on the first day of Christmas… equations
on day 2: equations and fractions
on day 3: equations and fractions… and order of operations
on day 4: … and simplifying algebra
on day 5: … and decimals
on day 6: … and indices
on day 7: … and transformations
on day 8: … and rounding
on day 9: … and area
on day 10: … and construction
on day 11: … and factorising
on day 12: … and long multiplication

by the time you reach the 12th day, it will take the whole lesson, but not so bad as it should be in the final week (not the best time to start a new…)
