In math, we were learning about inequalities. There is one inequality that needs a close dot on a number line. That is equal to or =. This sign needs a closed dot because it includes that number. For example, > with and equal under it means it it includes it. If you leave it out, it just means > with out a closed dot.
    I learned that an equal to needs a closed sot because it includes that number. I never knew this, but now I know it needs a closed dot. I can teach someone else like my brothers and sisters .
