Instructions for Use

Measure the Teddy Bears challenges students to measure in whole and half units, using an online ‘ruler’. There are 10 questions, each worth 10 points.

Click the “Continue” button. A teddy bear will stand up against a ruler. Tell how many units tall the teddy bear. Click “Continue” again to get another question.


Length  allows students to order pictures of people from tallest to shortest.

Click “How to Play” and read the instructions. Drag the players over the numbers to order them from tallest to shortest (where number 1 is the tallest). If you drag the player over the number correctly, the player will snap into place over the number and start moving. The activity will tell you when you have ordered all the players correctly.
