Flow Charts: Drawing the Steps of a Plan

  • Grade 6

  • BC6-AD-04

A flow chart for logging in with a password is built one shape at a time, with a key naming what each shape means: an oval for the start or end, arrows for what comes next, a parallelogram for an input or output, a diamond for a question and a rectangle for a step to do. The chart is then followed beside a small login screen, first with a wrong password that loops back to "Try again" and then with the right one that opens the account and reaches the end.

Transcript

What the lesson says

How can we draw a plan for logging in with a password?

We can draw it as a flow chart, made of shapes joined by arrows.

An oval shows where the plan starts or ends.

Arrows show what comes next.

A parallelogram shows an input or output, like typing the password.

A diamond asks a question: is the password correct?

Each answer gets its own arrow, one for yes and one for no.

If yes, a rectangle shows a step to do: open the account.

Then the plan ends at another oval.

If no, the output is a message saying “Try again”.

Then an arrow leads back, so the password can be typed again.

With a wrong password, the answer is no, so we go back.

With the right password, the answer is yes, so the account opens.

A flow chart draws a plan as shapes joined by arrows.
