Creating Simple Sequences

Active learning works because moving a body through space makes abstract directions concrete. When students physically act as the ‘robot,’ they feel how a turn changes left and right, turning directional language from guesswork into measurable logic.

Learning Objectives

1. Design a sequence of instructions for a robot to navigate an obstacle course.
2. Compare two different sequences of instructions that achieve the same outcome, identifying the more efficient one.
3. Justify the order of steps in a simple block-based program for a character's movement.
4. Create a short algorithm using directional language to guide a peer through a defined path.

Inquiry Circle

⏱ 30 min·Small Groups

Inquiry Circle: The Human Maze

Create a grid on the floor using masking tape. One student is the 'Programmer' who uses arrow cards to give directions, and the other is the 'Robot' who follows them to reach a target (like a toy kangaroo) while avoiding 'lava' squares.

Prepare & details

Design a sequence of steps to make a character move across a screen.

Facilitation Tip: During The Human Maze, place a cone at each decision point so students must name the exact turn before moving.

Setup: Groups at tables with access to source materials

Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template

Think-Pair-Share

⏱ 15 min·Pairs

Think-Pair-Share: Arrow Talk

Show a simple path on a grid. Students think about which arrows (Up, Down, Left, Right) they need to get from start to finish. They share their 'code' with a partner and check if it works.

Prepare & details

Compare different sequences that achieve the same outcome, evaluating their efficiency.

Facilitation Tip: During Arrow Talk, have students hold their arrows against their chests so the symbol’s orientation matches their body’s perspective.

Setup: Standard classroom seating; students turn to a neighbor

Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs

Simulation Game

⏱ 20 min·Pairs

Simulation Game: Fix the Glitch

The teacher lays out a sequence of arrow cards that leads to a dead end. Students work in pairs to find the 'wrong' arrow and swap it for the correct one so the path works again.

Prepare & details

Justify the order of steps in a simple program.

Facilitation Tip: During Fix the Glitch, give each group a red pen to edit the sequence before testing it again.

Setup: Flexible space for group stations

Materials: Role cards with goals/resources, Game currency or tokens, Round tracker

Teaching This Topic

Teach this topic by insisting on precision before speed. Require students to read instructions aloud exactly as written before acting them out. Avoid letting students skip steps or use vague terms like ‘around the corner.’ Research shows that early attention to detail prevents persistent errors later.

What to Expect

Successful learning looks like students giving clear, precise instructions that another person can follow without guessing. They understand that every step must be defined and that perspective matters when giving directions.

Watch Out for These Misconceptions

Common Misconception

During The Human Maze, watch for students who give directions as if the maze walker is facing the same way they are.

What to Teach Instead

Have the maze walker stand back-to-back with the instructor so both can see how their left hands point in opposite directions. Require the instructor to give commands from the walker’s perspective.

Common Misconception

During Arrow Talk, watch for students who use vague language like ‘go over there’ or ‘turn a bit’.

What to Teach Instead

Hold up a 3x3 grid and ask students to count steps aloud. Require commands to include a number and a direction, such as ‘2 steps forward’ or ‘1 step right’.

Assessment Ideas

Exit Ticket

After The Human Maze, give students a half-sheet with a simple grid and starting point. Ask them to write four directional commands to reach a target square. Collect and check for accuracy before they leave.

Discussion Prompt

After Fix the Glitch, display two different sequences that both reach the same spot. Ask students to vote on which they prefer and explain their reasoning in terms of efficiency or clarity.

Quick Check

During Arrow Talk, ask students to draw arrows inside a printed maze to show the path from start to finish. Circulate and check that arrows match the sequence they described aloud.

Extensions & Scaffolding

• Challenge: Ask students to create a sequence that includes a diagonal move using only four cardinal directions (e.g., Up, Down, Left, Right).
• Scaffolding: Provide a small grid with a drawn path already started; students fill in the missing arrows.
• Deeper exploration: Introduce ‘wait’ or ‘repeat’ commands by having students follow a sequence that includes pausing for three seconds before continuing.
