“One box, two ____.” Each line gives a word as one of something and asks for it as more than one. Most take an s; a good many do not, and those are the ones worth the page.
Plurals look like a single rule and are about six. A word takes -s until it hisses, and then it takes -es; a y after a consonant becomes -ies but a y after a vowel does not; several f words take -ves; and then there are the ones that change in the middle — children, men, feet, teeth, mice, geese — and the two that do not change at all. A child who has met all of those on one page has seen that there is a pattern rather than a rule.
The irregular ones are the sheet's real content, and they are irregular because they are old: the words English has used most often for longest are the ones that never got tidied up. “Sheep” and “fish” are on here for the same reason — they are the answer a child least expects to be allowed to write, and getting to write “two sheep” once is worth more than another twenty -s words.
The answers were decided when the sheet was built, so the key is the same page with them drawn in rather than a second attempt at the same questions — there is no way for the two to disagree. The number in the footer is the seed the sheet was built from: it is printed so that the identical sheet can be had again next week, rather than one that merely looks like it.

This page is one sheet out of a family that can print thousands. The topic is a setting rather than a different worksheet: ten of them — rhyme, syllables, word families, prefixes and suffixes, plurals, contractions, homophones, synonyms and antonyms — and each is asked in whichever of the three shapes suits it, written on a ruled line, circled from four, or joined up in two columns. How many questions and how many columns are switches beside them.
The settings travel in the link rather than on a server, so a sheet you make can be bookmarked or sent to another family as it stands — and the Name: line is printed blank, because there is nowhere in a shared link to put a child’s name. See what we don’t collect.
Word Jungle deals the sight-word lists as flash cards: the word is read aloud, in a sentence, and typed back — which is the half of spelling a worksheet cannot do, because paper cannot say a word out loud. A child who has just worked through a page is the one likeliest to race it, and the record book then knows which words they keep missing, so the next sheet can be exactly those.
