Patterns and Sequences: Unplugged Coding with Everyday Steps
Grade 1 · CS & Digital Fluency · NYS K-1.CT.2 · 40 Minutes
No devices required — this is an “unplugged” computer science lesson.
NYS-Aligned Standard
K-1.CT.2 — Identify and describe patterns and sequences; follow or create step-by-step instructions. NYS Computer Science and Digital Fluency Learning Standards (2020), Computational Thinking
Learning Objectives — “I Can” Statements
- I can find and extend a pattern.
- I can put steps in the correct order (a sequence).
- I can create simple step-by-step instructions for a task.
Essential Question
How do patterns and putting steps in order help us — and help computers — get things done?
Lesson Sequence
Hook / Warm-Up (8 min)
Clap a pattern (clap-clap-stomp, clap-clap-stomp). Students continue it. Then show a color-bead pattern and ask, “What comes next?” Introduce the word pattern.
Direct Instruction (10 min)
- Define pattern: something that repeats in a predictable way.
- Define sequence: steps that happen in a certain order.
- Connect to computers: “Computers follow steps in exact order — just like we do when we get ready for school.”
Guided Practice (12 min)
“Get Ready for School” sequencing: scramble picture cards (wake up, brush teeth, get dressed, eat breakfast, backpack on). Class orders them correctly. Discuss what happens if steps are out of order.
Independent Practice (8 min)
Students extend a given pattern (draw the next two shapes) and number a 4-step sequence (e.g., planting a seed) in order.
Closure (2 min)
Share: “Tell me a pattern or a sequence you saw today.”
SDI & Differentiation Block
Supports for MLLs/ELLs
Entering/Emerging (NYSESLAT Levels 1–2):
- Use physical pattern manipulatives (blocks, beads) instead of drawing
- Sequence with picture-only cards; no spoken response required
Transitioning/Expanding (NYSESLAT Levels 3–4):
- Vocabulary with visuals: pattern, sequence, order, first/next/last, step
- Sentence frame: “First ___, next ___, then ___, last ___.”
Supports for Students with IEPs
SDI Adaptation Dimensions: content, methodology, delivery
- Content: Use 3-step sequences and simple AB patterns
- Methodology: Hands-on manipulatives; act out the sequence physically
- Delivery: Allow pointing/placing instead of writing; pre-cut cards; extended time
Suggested Placement: ICT, Resource Room
Teacher Notes
Patterns and sequencing are the foundation of later algorithmic thinking and coding — name the connection explicitly (“you are thinking like a computer scientist!”).
