About this activity
Foot becomes feet, mouse becomes mice, and child becomes children — but deer and sheep stay exactly the same. At Pearl's Doubling Pond, the child reads a word and taps its correct plural, resisting the pull of the ordinary '-s' ending, in an interactive Grade 2 grammar activity.
The big idea is that not every plural is made by adding -s. There are two wrong choices each time, and they pull in opposite directions: for 'mouse' the child sees 'mice', 'mouses' and 'mouse' — one has added an s that does not belong, and the other has changed nothing at all. Adding an s is the healthy over-application of a rule the child has just learned, so the round is not about avoiding a bad habit; it is about knowing which words are exceptions. The child has to know the special plural rather than reach for the default ending, which is the whole point of learning irregular plurals.
It is aligned to Common Core L.2.1.b — forming and using frequently occurring irregular plural nouns. No timer, no score — just calm, playful practice.
