The Ra maths group has been learning to use addition strategies for solving problems with larger numbers.
Charlie has used Place Value partitioning - separating numbers based on place value and recombining.
Hannah has solved her problem by using tidy numbers. Rounding to a tidy number (that is easier to add) and then adjusting her answer (compensating) to get the correct result.
Lidia has used a similar Rounding and Compensating strategy when operating with tens (decades).
May has used the same strategy in two different ways. Great musical accompaniment as well May!
