Teaching points

Teaching point 1: A longer length can be described in terms of a shorter length using the language of ‘times’; the longer length can be calculated, if the shorter length is known, using multiplication.
Teaching point 2: A shorter length can be described in terms of a longer length using the language of fractions; the shorter length can be calculated, if the longer length is known, using division.
Teaching point 3: Other measures can be compared using the language of ‘times’ and fractions, and calculated using multiplication or division.
