### Stay Storyboarding All Summer Long

Lesson Plans by Anna Warfield

I can’t draw. I’ve tried to learn, but my hand does not move the pencil in quite the right way. Even though my hands don’t have the master skills of an artist, my brain is still very creative. Storyboard That is very easy to use and it's fun to use all year long!

### Diagram a Process

Lesson Plans by Anna Warfield

Instructions and processes are so much more easily understood when accompanied by visuals. When we storyboard a process or create a sequential diagram, we can focus on discrete steps, cause and effect, and sequence.

#### Storyboard Text

• Maybe I can help.
• GAH! Math is so stupid! It doesn't make any sense!
• This protractor thing is impossible!
• I will show you how to use it. Well, step 1...
• ﻿
• Make sure the protractor is not backwards! It makes life so much easier if you can read the numbers.
• Before we measure, tell me if this is an acute, right, or obtuse angle.
• It IS acute, so that means it measures less than 90 degrees. We already know the answer is between 0 and 90 degrees!
• The line doesn't reach the numbers!
• Acute?
• There are two parts of the protractor to help you get the angle in the right place: 1) an upside-down T at the bottom middle 2) the base line (0 degrees or 180 degrees)
• We want to place the protractor on top of the angle so the middle of the T is at the vertex.
• Acute angle! 40 degrees! Take that MATH!
• Rotate the protractor so the vertex of the angle is still at the T, but one leg of the angle is lined up with the 0 degree line.
• That's OK. Don't you remember that definition about angles? Two RAYS with the same endpoint? Rays go on forever, so we can just extend the legs of the angle.
• The legs of the angle are extended, so we just need to read the numbers. Our options are 140 degrees or 40 degrees. Which is it?
