Instructions for Use

Who’s Missing? allows students to identify and create the next element in the pattern.

To start Who’s Missing?, click on the “Who’s Missing?” link under Logic, strategy, and then click on the “Who’s Missing? 1” link.

A sequence of 2, 3, or 4 heads is displayed in a repeating pattern. You have to identify the pattern to figure out which head is next in the sequence. Then you have to build a head to fit the pattern.

To use Who’s Missing?, click on the hat, the colour, and the shape you need. Then click on the resulting head. If it's the correct one, it'll replace the question mark. If not, the word “NO” is displayed in red just under the head and you will have to correct the head you built.

Click on the “New game” button to get a new pattern.

Dr. Seuss Sticker Game allows students to complete a pattern.
