Example

Example: hard level, six rows a page, for kindergarten

Level Hard (a different kind of thing), Rows per page 6, Pictures In colour, Pages 2, Add the answers on, worksheet number 1, US Letter. Each row has four pictures and one does not belong.

  1. Hard rows follow five rules: another kind among things of one kind, the only one that cannot fly, the only one not from the sea, one picture mirrored, or one missing a small detail.
  2. The odd one gets a colour the others do not share where it can, so colour never points to a second answer.
  3. Answer pages follow, with the odd one ringed in red.
Row Pictures on page 1 Odd one out Why
1 snail, whale, fish, crabsnailthe only one not from the sea
2 bed, lamp, balloon, tableballoona toy among furniture
3 four dressesthe 2nda small detail is missing
4 four leavesthe 4thit is mirrored
5 octopus, T-shirt, hat, mittenoctopusan animal among clothes
6 ball, rocket, teddy, kiterocketa vehicle among toys

odd-one-out.pdf: 12 rows on two pages and two answer pages. Ask “why?” for each row: “the only one that does not live in the sea” is the reasoning the sheet is for.

How it works

  1. Choose easy or hard and how many rows on a page.
  2. Pick colour or outlines and how many pages.
  3. Print; children circle the one that does not belong — and say why.

Frequently asked questions

What do children learn?
To look closely and to sort: noticing what is different, and thinking in groups — fruit, animals, vehicles — which is the root of reasoning.
What makes the hard level hard?
The pictures are all different; the odd one is a different kind of thing, like a bird among animals that swim, or a small detail that is turned the other way.
Why ask children to explain?
“It is the only one that cannot fly” turns a guess into reasoning and builds vocabulary.
Are the answers included?
Yes, with the odd one circled.
How many pictures are in a row?
Easy: five, four the same shape or picture and one different; about two rows in five are shapes. Hard: four, three of one kind and one not, or four the same with one mirrored or missing a detail.
Can a row have two right answers?
Each row is built against it: the odd one is never of the row’s kind and the rest all are, and where it can, the odd one has a colour the others lack, so colour does not suggest a second answer.
Is anything uploaded?
No. The worksheets are made in your browser.
