Are you ready for a fun way to learn about decimals? Today, we're going to play a game to explore the concept of decimals.

But first, let's review what we already know about decimals. Decimals are a way of expressing parts of a whole number. For example, if we have 0.5, this means we have half of a whole. If we have 0.25, this means we have a quarter of a whole.

Now, let's get ready to play our game! We'll be using a deck of cards to practice working with decimals. Each card will have a decimal number on it, and we'll use them to practice adding and subtracting decimals.
