1 One or many
Language Singular and plural: this is a book / these are three books
- Hold up one pen: the class says this is a pen. Hold up three: these are three pens.
- Do six or seven objects with the whole class together, alternating one and many unpredictably.
- Split the room in two. Hold up objects; the half that says the correct full sentence first scores. A half that says only the noun scores nothing, and say so before you start.
- Finish with something awkward on purpose - two dusters, or a handful of chalk - and let them argue about it in English.
Variation Harder: use objects whose plural is irregular, and teach these are three children as a whole phrase rather than as a rule.
Large class Halves rather than rows, because the sentence has to be said together and forty-five pupils in two groups can chant a sentence in unison where six teams cannot.
