**Instructions for Use**

**Which Holds More?** allows students to compare two containers of water and determine which container holds more.

Click “How to Play” and read the instructions. You will be shown two clear containers and watch water being poured into each container. Click on the container that you think holds more water.

**Can You Fill It?** challenges students to use smaller containers of water to fill a larger, empty container—without spilling over.

Click on “Capacity”, then click on “Can You Fill It?” Click “Play.” You will be shown a large empty container. There are three smaller containers full of water. You must choose the smaller containers to use to fill up the larger container, without spilling over. The object of the game is to fill up the large container with water in the fewest pours possible. Click “Next” to try filling another container.
