Grade 4 Singular & Plural: Free SOF IEO Practice | Glovoy

One becomes many, and English has rules and surprises: cats, but mice; boxes, but sheep.

It’s foundational grammar that quietly underpins all good writing, introduced early and revisited until it’s automatic. A regular SOF IEO question type in the lower grades. Try the questions below: the irregular ones are secretly the most fun.
