What's on the sheet

5 rows of 4 Oopsies
The rule is always a color: yellow, green, teal, purple, red or orange
The odd one is a color far from the row's color

Printed instructions: “In each row, circle the Oopsie that doesn't belong. Hint: look at the colors!”

About this odd one out sheet

Each row has four Oopsies: three of the same color and one from a clearly different color, like a purple Oopsie in a row of yellow ones. The generator measures the color each drawing really shows, so a "green" Oopsie always looks green. A good first odd one out, and a chance to name colors together.

Tips for parents and teachers

Ask your child to say the rule out loud: "they're all green, except this one".
Cover the odd one and ask what the others have in common.
Print in color: this sheet is all about color.

The skill it trains: visual discrimination

Visual discrimination is the ability to notice how things you see are alike and how they differ: their shape, color, size and small details. It is what tells a child that b and d are two different letters, or which of two almost identical pictures has an extra button.

Visual discrimination: what it is, signs a child finds it hard, and more activities

Play it in Oopsies: Odd Ones

💡 Odd Ones

Every Oopsie on screen shares a feature with the one to find: its color, an accessory, its smile or its shape (all red, all with a mustache, all with glasses…). That shared feature never gives it away, so children compare faces and small details.
