Help the amateur baker prepare for the grocery store by dragging the correct noun forms into the blanks.
My famous cake recipe requires three apples, but I only have one banana in my kitchen. I also need to buy two large eggs from the market.

apples & eggs: In English, when you have more than one of a countable noun, you must add an -s or -es to the end of the word.
banana: Because there is only "one," the noun remains in its singular form without an -s.
Tip for Vietnamese speakers: Even though numbers like "three" or "two" already tell us there is more than one, English still requires that extra "s" at the end of the noun!
Grammatical number
Subject-verb agreement: the verb must match the subject's number, not the nearest noun. The list of items is long (✅) — not are, because the subject is list (singular), not items. This "attraction" error is the most common number mistake.
Grammatical number is the singular/plural system affecting nouns, pronouns, and verbs. Agreement means making them all match.
Diagnostic: find the actual subject (ignore prepositional phrases between subject and verb). Is it singular or plural? Match the verb to that.
Noun
Noun vs verb: the two core word classes. Nouns name things; verbs describe actions/states. Many English words can be both (run, play, cook, work) — only the sentence slot tells you which role it's playing. The run was exhausting (noun) vs I run every day (verb).
A noun names an entity. It interacts with articles, determiners, forms plurals, and controls verb agreement and pronoun choice.
Diagnostic: can you put the/a before it or pluralise it? → noun. Does it describe an action with tense? → verb. Can it do both? → check the sentence context.
A1 | Elementary | Beginners
A1 vs A2: A1 covers isolated survival phrases (Where is…?, I am…, How much?). A2 handles connected sentences about familiar routines and simple past events. If you can manage short fixed phrases but not string together original sentences about your day, you're still A1.
A1 is the entry level of the CEFR: greetings, introductions, numbers, basic present tense, and core function words.
Diagnostic: can you describe yesterday using past tense? No → A1. Yes → you're moving into A2.
Easy
Easy vs Medium vs Hard: Easy = one rule, obvious answer, A1–A2. Medium = one rule but realistic distractors, A2–B1. Hard = interacting rules, edge cases, B2+. Start Easy to check you have the basics before moving up.
The Easy tag filters for single-rule, short-sentence, common-vocabulary challenges designed for beginners or for anyone wanting a confidence check on fundamentals.
Diagnostic: if you get Easy questions wrong, stay here — your foundations need work. If they feel trivial, move to Medium.
