Learning Objective
I can use symbols to represent unknowns.
Today we will learn how to use symbols to represent unknowns. Math helps us solve problems and understand the world around us.
Representing a number means showing it in different ways. You can represent 15 with: numerals (15), words (fifteen), pictures (15 dots), base-ten blocks (1 rod and 5 units), or on a number line (point to 15). Using different representations helps you understand what the number means. When you solve problems, choose the representation that makes the most sense for that problem!
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 use symbols to represent unknowns. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
