I don't like blue. - Flashcards for the chant: "Do you have a (green) cap?"
Here are 2 sets of flashcards that are more for teaching the chant rather than vocabulary although you could use them to teach count vs. non-count nouns with reference to the articles "a" and "an". Don't let the kids say "Do you have 'a' green pants?" "Do you have 'a' blue shoes?" etc. They (the kids) will get stuck on "Do you hava" for everything and may thus continue to sound very glorified about it for the rest of their lives... So, I'll leave it up to the ALTs and HRTs out there to decide whether to burst their bubble.
As for me, I think right around this time the kids are old enough to understand we in the "English World" don't treat all nouns the same. If they ask you why, just tell them "Doraemon" said so. Or you could tell them if you put an 'a' in front of an __s word you might make an 'a __s' out of yourself in front of other people. He he he.... it's just a joke, ok...
Actually, the plural is called "fukusu-kei" in Japanese and "a" or "an" equals 1 so we never put it in front of a pluraled word... "fukusei mono no mae ni, "a" wa iranai desu..." (unless you are using a counter, but mostly only the Grade 6ers can get that). The HRT can save you tons of time if he or she can explain, translate, or review this in one minute or so.
By the way, didn't you already explain about milk, ice-cream, and juice and all that other stuff back in Lesson 4: "I like apples." vs. "I like milk." To simply put it just ask the kids why we don't have an 's' after milk (and hope that some smart kid can figure it out and explain it for you in front of the class). Works for me, and saves me a lot of time. (It's amazing how well kids can understand each other...) Or check that post here at eigonote_book_1_unit_4_lesson_1_archives.html
