How it works

A robot does only the steps it is given.

A bug is a mix-up in the steps. It is nobody's fault.

We fix the steps and try again.

Worked examples

Mia's fence

Mia gives Bo three cards: paint, paint, paint.
Bo does every card, but the brush is dry, so the fence stays plain.
Mia sees that a step is missing. That mix-up is a bug.
She adds a card at the start: dip the brush. Now the paint rolls on.

Bo on the board

Bo starts at the top left, facing right, and goes forward twice.
The second step bumps a rock. That is a bug.
Fix the steps: turn right, forward twice, turn left, forward twice.
Now Bo lands on the star.

Bo walks the dotted way to the star.

A bug at home

Pick a job with a grown-up, like making a sandwich.
You say the steps, and the grown-up does only your steps. Leave one out, like the bread.
When the job goes silly, say, that is a bug! Then add the missing step and try again.

Try it again

After a fix, run the steps once more.
If another mix-up shows up, fix that too.
Fixing bugs is part of the job, and nobody is in trouble.

Words to know

bug: A mix-up in the steps.
step: One thing for the robot to do.
fix: To change the steps so they work.
card: One step, written down.

Watch out for

A bug is not the child's mistake, and it is not the robot's. Bo did exactly what the steps said.
Do not say bad robot. Look at the steps instead.
Do not give up. Fix the steps and try again.
A new step can be missing from the start: look there first.

Try it

Why did the fence stay plain?

The brush was dry, because no card said to dip it. Bo did every card. A step was missing.

What is a bug?

A mix-up in the steps. A bug is a mix-up we can fix.

Is a bug anyone's fault?

No. Bo did fine and Mia did fine. We just fix the steps.

Bo bumps a rock. What do we do?

Fix the steps and try again. A bump is a bug, so change the steps.

For grown-ups

Pick a job with a grown-up, like making a sandwich. You say the steps, and the grown-up follows only your steps, so leave one out by mistake, like the bread. When the job goes silly, say "That is a bug!" and then add the missing step and try again.

When something goes wrong at home, say 'that is a bug, let us fix the steps' instead of 'that is wrong'. Your child hears that mix-ups are normal and fixable.
