Straighten is like when you have a wiggly, squiggly line, and you make it all nice and straight like a ruler. Imagine your spaghetti noodle is all twisty, and you gently pull it so it’s not twisty anymore. That’s making it straight! It’s like when your shoelaces are all tangled up, and you smooth them out so they’re neat and straight.
Think of your hair after you wake up. It might be all messy and sticking out everywhere. When you brush it, you make it nice and straight and tidy. Or like when you have a bent straw, and you make it straight so you can drink your juice easily.
Straightening is like when you have a piece of paper that’s been crumpled into a ball. You flatten it out so it’s smooth and straight again. Or when you have a line of toy cars, and you line them up so they’re all in a neat, straight row. It’s all about making things neat, tidy, and easy to use!
