For this 15 minute warmer/ starter activity I give the students a mini-whiteboard and give them 15-20 seconds to identify the odd-one out. I use this at the beginning of the school year and throughout the year for revision. It is possible that the students can come up with other possible answers and I enjoy challenging them to think outside the box! I just use the second slide, but you could use the first slide and ask the students to figure out the odd-one-out for all the phrases in teams.
Adjectives, the odd-one-out and rules covered:
beau mauvais gentil intéressant
intéressant follows the noun !
jeune allemand vieux nouveau
allemand follows the noun !
grande petite rouge importante
rouge, because the others are made feminine by adding an “e”, rouge already has one!
marron bleu olive bleu-clair
bleu because the other adjectives are invariable as they are both nouns and adjectives or are hyphenated.
fraîche verte fausse blanche
verte is not an irregular feminine form i.e. it follows a pattern the others don’t : frais – fraîche, faux – fausse, blanc –blanche
meilleur ancien cher propre
meilleur because the others have one meaning if they are placed before the noun and another if they are after it. Ancien = former/ old, cher = dear (beloved)/ expensive, propre = own/ clean
