Guess My Button

Sorting and classifying can help you discover a lot about the patterns of objects, people, and places. To begin, you might ask yourself a few simple questions: What's the same? What's different? And this is the strategy you'll need for Guess My Button. The computer has secretly picked out one of the sixteen buttons you see on the screen. What you need to do is determine which button it is by selecting questions about the attributes of the buttons.


Set Game

Try the "SETS" Problem of the Day! The object of the game is to identify the 6 'Sets', of three cards each, from 12 cards laid out on the screen. Each card has a variation of the following four features: 1.COLOR: Each card is red, green, or purple.

2.SYMBOL: Each card contains ovals, squiggles, or diamonds. 3.NUMBER: Each card has one, two, or three symbols.

4.SHADING: Each card is solid, open, or striped.

A 'Set' consists of three cards in which each feature is EITHER the same on each card OR is different on each card. That is to say, any feature in the 'Set' of three cards is either common to all three cards or is different on each card.
