Today's Lesson

Today we will learn about skip count by 10s to 120. Math helps us solve problems and understand the world around us.

Skip counting means counting by a number other than 1. When you skip count by 2s, you say: 2, 4, 6, 8, 10... When you skip count by 5s, you say: 5, 10, 15, 20, 25... When you skip count by 10s, you say: 10, 20, 30, 40, 50... Skip counting is a pattern—you add the same amount each time. It's a faster way to count and helps you get ready for multiplication!

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.
