🧩 Introduction to Algebraic Thinking

Algebraic thinking is like being a math detective! Instead of just computing answers, we learn to look at expressions as puzzles that need to be balanced. This topic builds the foundational logic needed to understand variables, balance mathematical statements, and work backward to find hidden parts.
• True or False Equations Using the Equal Sign (=): Many students think the equal sign means "and the answer is...". But in algebra, the equal sign acts like a balance scale! It states that everything on the left side must have the exact same value as everything on the right side. For example, 5 + 3 = 6 + 2 is a True equation because both sides equal 8. However, 4 + 2 = 5 + 3 is a False equation because 6 does not equal 8.
• Missing Numbers in Addition and Subtraction: Finding a hidden value (an unknown) that makes an equation true. We use empty frames, blank boxes, or…
