Introduction to Repeating Patterns: AB and ABC Sequences

Scratch Garden

This engaging animated video introduces early learners to the fundamental concept of patterns through humor, movement, and visual examples. Hosted by a quirky red character, the lesson defines a pattern as something that repeats again and again, moving from simple auditory and physical examples to more complex visual sequences. The video uses a scaffolded approach, starting with basic identification and moving toward prediction and problem-solving. The content covers key mathematical concepts including identifying repetition, distinguishing between AB and ABC patterns, and recognizing the "core" (the unit that repeats). It employs memorable and silly examples—like a "Popcorn, Unicorn, Mustache" sequence—to maintain student interest. The video also introduces the algebraic concept of labeling patterns with letters (A, B, C) and demonstrating how patterns extend infinitely unchanged. Ideally suited for early elementary classrooms, this video serves as excellent direct instruction for math centers or whole-group learning. It encourages active participation by asking students to move their bodies, say terms aloud, and predict what comes next. Teachers can use the built-in pause points and questions to check for understanding, making it a versatile tool for introducing algebraic thinking and logic skills.
