In my class, I used this game to clarify the collective nouns as we practiced them. As we worked through the Kahoot questions, I kept a table on the side of the whiteboard listing the collective nouns, and what they consisted of. As we encountered new collective nouns, I put them up on the table, and elicited from the students what the collective nouns consisted of. An example is below:
I was looking for a suitable video to introduce collective nouns to my low-level ESL students. While searching through the Internet, I discovered that much of the material available on collective nouns seems to be based on obscure collective nouns for groups of animals (e.g. a murder of crows, a parliament of owls, etc.) rather than explaining more practical and common collective nouns. And this video falls into that as well, particularly the second half of it.
Nevertheless, it's short, it's upbeat, it's entertaining, and at least some of the collective nouns that it introduces are useful. In my class I played this video for my students. They were tasked with writing down at least 6 collective nouns from the video. In my class, I needed to play it a couple times for them to accomplish this. I used this as a way to introduce the topic of collective nouns.
Recently I was teaching singular/plural nouns to low-level 5th grade students. I started out with a very basic kahoot game that simply tested whether or not students could identify basic plural forms. That game is here: Basic Singular and Plural
Once that basic Kahoot was mastered, I moved on to a Kahoot that I found that tested irregular plural forms: Singular & Plural. I made a copy of it so that I could make my own edits on it. These edits were mainly to make the prompts more based on pictures, but I did add in a couple questions, and also deleted a copy questions. My edited copy is here: Duplicate of Singular & Plural.
In my edited copy, I also made a move to introduce collective nouns, specifically: class, family, army
