Learning Objective
I can count by 10s to 100.
Today we will learn how to count by 10s to 100. Math helps us solve problems and understand the world around us.
Skip counting means counting by jumping over numbers in equal steps instead of counting by ones. Counting by 2s: 2, 4, 6, 8, 10… (even numbers). Counting by 5s: 5, 10, 15, 20… Counting by 10s: 10, 20, 30, 40… 100. Skip counting builds number sense and is a stepping stone to multiplication—counting by 3s is the same as the 3 times table: 3, 6, 9, 12… Use a hundreds chart to see the patterns: when you count by 5s, the pattern always lands on a 5 or 0. Skip counting by 10s is especially important because our number system is base-10.
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.

Teaching Tip
For younger learners: Use concrete objects and hands-on activities when teaching count by 10s to 100. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
