I have expanded the quizzes on AM/IS/ARE in the kids' section of Road to Grammar. Previously, there was only one quiz, now there are four:
1 AM/IS/ARE with pronouns.
2 AM/IS/ARE with singular and plural nouns, including names.
3 AM/IS/ARE with various tenses, passive voice and uncountable nouns
4 Question form of AM/IS/ARE
