You completed REPEATING PATTERNS — a line-up where the same colors come back again and again in the SAME order! When you saw Red-Blue and knew Red-Blue came next, you found the pattern unit (the part that repeats) and used it to PREDICT what comes next. You mastered AB patterns (two colors), AABB (two of each!), and ABC (three in a row). Spotting patterns is a SUPER thinking power — patterns are in the days of the week, the seasons, music beats, your heartbeat, stripes, tiles, even how leaves grow! Once you see the repeating part, you can ALWAYS guess what's next. That's real number thinking — and YOU just used it! 🦋
