Length and height
Spring term · 7 skills
Compare first, then measure with something, then measure with a ruler — in that order, because a ruler means nothing until you have measured with cubes.
Mass and volume
Spring term · 8 skills
Heavier and lighter on a balance; fuller and emptier in a jug. Both are compared long before either is measured.
Equal groups

Summer term · 8 skills
A half is one of two equal parts — of a shape, or of a group. The word "equal" is the whole lesson.
Position and direction
Summer term · 7 skills
Where a thing is, and how far it has turned. Quarter turns here are the same quarters as in fractions, on purpose.

Money

Recognising coins and knowing what each one is worth. A 2p is bigger than a 5p, which is the first time size and value disagree.
Time
Summer term · 11 skills
