Learning intention

- I can identify its preposition and object.
- I can use a comma to clarify an introductory phrase boundary.
- I can distinguish plurals from possessives.
- I can show singular, plural, shared and separate possession.
Board 1: complete phrase
under the old bridge = preposition under + object noun group the old bridge.
Do not select only under.
Board 2: introductory comma
During the final minutes of the match, the crowd became silent.
Mark the whole introductory phrase first; then place the comma at its end when the boundary needs clarification.
Board 3: apostrophe meaning
- dogs = more than one dog
- dog’s collar = one dog owns the collar
- dogs’ leashes = several dogs own the leashes
- children’s games = irregular plural possessive
Board 4: shared versus separate
Sam and Priya’s project → one shared project.
Sam’s and Priya’s projects → separate projects.
Meaning first, apostrophe placement second.
