I REALLY dislike cutting out paper activities. This dislike is what prompted me to create my first activity (drag and drop Geometry Proofs) with technology. When my team found a fun Memory Game activity I CRINGED at the thought of cutting out all of those sets and then finding a place to store them.
I went through a few attempts to create a memory game in Google Slides. I thought about linking pages but I needed to see two at a time. I wanted to remove one element “on click” but I could only get them to dissolve in a specific order. I settled on deleting the cards and it worked like a charm.
I know, you are all wanting to create your own memory game now! You’re in luck, I have a quick tutorial for you!
I used the basic white background so it didn’t distract from game. Place all of the “back side” of the cards, the part with the content, evenly spaced on your background. I ended up putting boxes around mine to help me get them spaced. I love that Google Slides give you guide lines as you place your items.
You can also use the arrange menu and select horizontal or vertical and align them perfectly.
This is probably the most important step. We don’t want the background to be deleted while we are playing the game. Once you have the “back side” set exactly as you want it, go to file – download as – and pick jpg or png. 
Once it’s downloaded, delete all of your elements. I know, that’s scary. I do go into my history and set that version as editable background, you know, just in case you made a mistake.
Now you will set this as the background. There is a background button on the top middle of the menu bar. Once you click it, select your image and set as the background. Now you can breathe again. All of that work is still there, not gone forever!
We are ready to make the cards. I used the rectangle shape and held down the SHIFT key to make sure I had perfect squares. 
I used the gradient tool to select the background and put a ? on it just like the original memory game.
One suggestion from my students was to make this an image so the ? wasn’t editable. Sometimes when clicking on the square they got the ? instead.
You can copy and paste these and use the align tool again to get them close to where you want them. Then move them exactly where you need them.
Create the rules page. I’ve included the image of my rules page below. It explains how you would “flip” the cards over to play the game.
Play the game!
I sent this to my students through Google Classroom and said make a copy for each student. They enjoyed it and learned from the activity as well.
If you make a memory game, please share! I love to see how people use my ideas.
