The specific outcome includes representing decimals to thousandths; whereas the previous curriculum included reading and writing decimals to thousandths in Grade 6.
The specific outcome includes relating fractions to decimals (to thousandths); whereas the previous curriculum included only decimals to hundredths in Grade 5.
The specific outcome includes comparing and ordering decimals (to thousandths) with specific strategies outlined; whereas the previous math curriculum focused on comparing and ordering fractions and decimals to hundredths with no strategies suggested.
The specific outcome includes adding and subtracting decimals (limited to thousandths); whereas the previous math curriculum focused on adding and subtracting decimals to hundredths with emphasis on concrete, pictorial and symbolic connections.
