Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Gather Stuff You Need
Stuff you'll need
1) a leather spectacle sleeve
2) a ruler
3) a pin or needle to mark lines on leather ( I used a compass pin)
4) stuff you would basically keep in a pencil case
Step 2: Leather Sleeve to Ruler
Mark points on the leather sleeve from the ruler so that they're visible
Step 3: Lable the Marks
Lable the marks made on the sleeve ( I used a ball pen but you can use a permanent marker of some sort with a brighter colour) let the labels dry.
Step 4: You're Done
Use your sleeve as a pencil case and a ruler
