Key Instant Recall Facts
KIRFs (Key Instant Recall Facts) are designed to support the development of the mental skills that underpin much of the maths work in school. They are particularly useful when calculating, be it adding, subtracting, multiplying or dividing.
Instant recall facts help enormously with mental agility within Maths lessons. When children move onto written calculations, knowing these facts is very beneficial.
For your children to become more efficient in recalling them easily, they need to be practiced frequently and for short periods of time.
