Okay, so imagine you and your best friend really like playing a game of basketball against each other. Now, imagine your best friend lives in a different country and you've never played basketball against people from that country before.
The Summit Series was like that. It was a big game of ice hockey between two countries: Canada and the Soviet Union (which now is Russia). The people who were organizing the game thought it would be really exciting for everyone to see which country was better at playing ice hockey.
So, in 1972, Canada and the Soviet Union played eight games against each other. It was really exciting because Canada had some of the best ice hockey players in the world, but no one knew how good the Soviet Union was because they had never played against each other before.
The games were played in both Canada and the Soviet Union. People from both countries were really excited to watch the games, and it became a really big deal.
In the end, Canada won the series by winning four games and tying three, while the Soviet Union only won one game. It was a really big deal for Canada because it showed that they were really good at playing ice hockey, and it made everyone in the country really proud.
So, the Summit Series was just a big game of ice hockey between two countries that everyone was really excited about. It was a really big deal because it showed which country was better at playing ice hockey, and it made people feel proud of their country.
