Too and enough describe whether something is more or less than we need. Too goes before an adjective or adverb and means 'more than is wanted': This coffee is too hot to drink. Enough goes after an adjective or adverb but before a noun: He isn't tall enough. We don't have enough chairs.

The point is usually taught at A2. The main difficulties are word order (enough tall instead of tall enough), confusing too with very (The movie was too good, when learners mean very good), and choosing too much with uncountable nouns and too many with plural countable nouns. Learners also need the follow-on patterns too/enough + to-infinitive and for + person: It's too cold for us to swim.

Teaching tips: Too / enough

Use real objects or pictures (a tiny T-shirt, a huge shoe) to elicit It's too small and It isn't big enough.
Watch for 'too' used as a positive intensifier: too means there is a problem, so The party was too good sounds odd; use very or really.
Drill the two positions on the board with arrows: too BEFORE the adjective, enough AFTER the adjective but BEFORE the noun.
Set a problem-solving speaking task, such as why an apartment is unsuitable, so learners combine too, too much/many and not enough naturally.

Questions teachers ask

What is the difference between 'too' and 'very'?

Very simply intensifies (The bag is very heavy), while too means it is more than is acceptable and there is a consequence (The bag is too heavy to carry).

Does 'enough' go before or after the noun?

Before the noun (enough money, enough time) but after adjectives and adverbs (old enough, quickly enough).

When do we use 'too much' and 'too many'?

Too much goes with uncountable nouns (too much sugar) and too many with plural countable nouns (too many cars). Too much can also follow a verb: You worry too much.
