Learning objectives

Use first, second, third and later position words accurately
State a viewing or ordering direction before assigning ordinal positions

Concepts and principles

Ordinal numbers tell place in an ordered sequence; cardinal numbers tell how many.
Positions can reverse when the reference direction changes.

Examples and worked solutions

Separate teaching example (not verified as a native game question): Four planes are queued from left to right. Which ordinal position is the third plane?: Worked solution: Third from the left, given the stated direction.

Guided practice

Read whether the displayed question counts from left, right, first arrival or another basis
Locate the referenced object before choosing a dropdown answer
Explain the ordinal position in one sentence

Expected observations and explanations

An object can be second from one end and third from the other if the group has four objects.

Assessment questions and answers

What does “fourth” tell you?: Answer: Position in an ordered group, not total quantity.
Can a plane be first from the left and last from the right?: Answer: Yes. Position depends on the stated reference direction.
