I can review and apply knowledge of place value through games.

Today's Lesson

Today we will learn how to review place value through games. Math helps us solve problems and understand the world around us.

Place value means the value of a digit depends on its position in the number. In the number 23, the "2" is in the tens place (worth 20), and the "3" is in the ones place (worth 3). So 23 = 20 + 3. This system helps us write any number, no matter how large, using just ten digits: 0-9.

Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!

Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
