Irregular Plural Nouns

We've been doing some review work on irregular plural nouns. When I covered this earlier, a few of my kids were still a liittttlle shaky on the whole concept of nouns (compared to verbs and adjectives), so I decided to touch on it again. This is a writing activity we did last month in our writing journals:

This was enough for the majority of the class to "get it," especially after writing sentences that used irregular plural nouns.  But to let my stragglers catch up to the pack, I did this activity:

I had a list of 28 nouns one for each student, with several nouns for each of the following singular-to-plural rules: 
~add -s, 
~add -es, 
~change y to i and add -es, 
~change f to v and add -es, and 
~keep the plural noun the same as the singular. 

I then drew name sticks to assign students to a word, and they had to draw and label the singular noun on one side of the page, and draw and label the plural noun on the other half of the page, using the appropriate rule.  

The best part of this activity came the following morning during reading centers, when the kids had to sort each other's labeled drawings according to the rule they used to make the noun plural.  They recognized each other's work, and loved using their own work to do the sort. I guess there are situations where my beautifully crafted and laminated flash cards aren't the best way for kids to learn!  (While my ego took a slight blow, I realized that it's a lot less work for me if the kids make their own sorting cards for grammar and spelling conventions.)

To really drive the concept of irregular plural nouns home, I assigned this app in one of my iPad centers. In this free app, the kids are given a sentence that uses an irregular plural noun, except they have to decide what form of the noun should be used. For example, "The boy saw three ______ in the forest."  Then the students have to drag either the word deer or the word deers into the blank.
