Do you know what the letter is? Think of the answer in your head and then click on the white space of the card to flip it over and see if you were right!

Advance the cards by clicking the arrows below the letter.

*If the cards are moving on their own, you likely have the "play" button clicked (highlighted). Unclick the "play" button and then use the arrows to advance the cards manually.

You can also shuffle the cards by clicking "shuffle" in the bottom left corner.

Everyone's computer is different. If you need to zoom in on your screen to better see the letters, no problem! You can do that by following the instructions here:

For Windows: Press Ctrl and the plus key (+) to zoom in. You can press this keyboard combination as many times as you need to zoom in for a closer look. Press Ctrl and minus key (-) to zoom out.

For Mac:  Hold Command (⌘) and press the plus key (+) to zoom in, or the minus key (-) to zoom out. Simply keep holding the plus or minus key to continue zooming instead of additional tapping or repeating the shortcut.
