📈 Grammar A2-7: Comparatives and superlatives: consolidation

A1 introduced -er and -est; this material makes them safe. Learners get a four-question procedure instead of a feeling: two things or a whole group, how many beats the word has, whether it is one of the three rebels (good, bad, far), and the one-change check. The full spelling table is here — just add the tail, add only r or st after -e, double the last letter after one vowel plus one consonant, turn y into i — together with the two errors that outlive A1: the double comparative (more bigger) and the superlative that has lost its the (busiest day). Thirty multiple-choice items, a twelve-word beat sorter, six reveal cards on the irregulars, six error corrections and a school-magazine text where every comparative and superlative explains its own choice.
