Here's another quick game we've been playing this week in honor of St. Patrick's Day.
Take two small containers. Place shamrock cards in one and gold coins in the other. (The shamrock cards have green stickers on the back.)
Take out two shamrocks and flip them over. Count the dots and take out the corresponding number of coins for each dot. Add the two numbers together.
This game is quick to set up is a good independent activity.
