Speed Giving Games involve having people make a decision between two charities. In SGGs, participants who come to the table are given a 1-minute introduction to the concept of effective giving and the two charities involved in the SGG, and are then invited to make a decision about which of the two charities to support. Their vote results in a dollar each going to either charity, sponsored by an outside party, usually The Life You Can Save. For the SGG, we chose GiveDirectly as the effective charity, and the Mid-Ohio Food Bank as a local and not so effective charity.

Will keep in mind about the photo, thanks for the feedback.

It's not stated so explicitly, but it sounds like you're told about an effective charity and a not-so-effective charity, asked to choose one, and The Life You Can Save gives one dollar to whichever charity you chose. The context is used to spread ideas about effectiveness and encourage critical thinking about philanthropy.

And I guess this is the packet that he talked about giving to the SSA members, which describes how to run your own giving games.
