Primary 5 Mathematics
Percentage, rate and area of a triangle all arrive in P5, and each one asks your child to hold two ideas at once. This is the level where gaps from P3 and P4 usually surface, because these topics assume fractions are already comfortable. Worth checking the earlier lists if something here is not landing.
