rain + bow = ___
Each row prints two words joined by a plus sign and a line to write the compound on. Six to fourteen rows a sheet, drawn from a bank of fourteen pairs and shuffled, with the answers on their own page.
Why compound words are worth a lesson
Because they are the first place a child sees that long words are made of shorter ones they already know.
A reader who has met butterfly as a single unfamiliar shape has to learn it whole. A reader who can see butter and fly inside it has decoded it from parts, and that is the same skill that later gets them through unhelpfulness and photosynthesis. Compound words are where the habit starts, and they start early because the parts are words a five-year-old already has.
The meaning is not always the sum
This is the interesting part and the part worth a conversation.
Some compounds mean exactly what their parts say. A toothbrush is a brush for teeth. A seashell is a shell from the sea. Others do not: a butterfly is not a fly made of butter, and a rainbow is not a bow that rains.
Ask a class which of the completed words on their sheet mean the sum of their parts and which do not. It takes five minutes, it produces some genuine argument, and it is the beginning of understanding that words carry history rather than logic.
Spelling: they join with nothing between
No hyphen, no space, no letters dropped. Foot plus ball is football, with both t's intact even though nobody pronounces them separately.
That is worth stating, because the words on this sheet are the well-behaved kind and English does not stay that tidy. Ice cream is two words. Well-known takes a hyphen. Which form a compound takes is largely a matter of how long it has been in the language, and the honest answer to "how do I know?" is that you look it up.
What the generator asks for
Problems from 6 to 14, a worksheet title, an instruction line you can rewrite, optional Name and Date fields, and the answer key. A4 or US Letter.
Extending it
Work backwards. Give a compound and ask for its parts, which is harder and catches children who completed the sheet by joining letters without reading either word.
Or take one part and collect compounds from it. Snow gives snowman, snowball, snowflake, snowstorm, snowdrop, and a class can usually find more than you expect.
Print at 100% on A4 or US Letter.
