# Notation for Domain and Range Foldable

Post Contents

Tomorrow, my Algebra 2 class will begin identifying the domain and range of a function from a graph.  I created a domain and range foldable to help my students keep the three different notations separate.

I used a basic three door foldable.  The first flap contains all of the information about set notation.  The second flap features algebraic notation, and the third flap focuses on interval notation.

I’ve sized my template that is sized to fit in a composition notebook below.  My students will add this to their Algebra 2 interactive notebooks.  This is one of my favorite and most versatile foldables.

Over my years of teaching Algebra 2, I did several variations of this same foldable.

Do you teach any of this in algebra 1?

We do domain and range using set notation. But, we're only looking at discrete sets of points.

Thanks for making this. I'm about to teach my Algebra 2 students about interval notation and I needed a good way for them to organize their notes. What you made will really help.

Wow! That looks great! I remember learning this and being somewhat confused about it, but this seems like a great way to teach it and it makes so much sense! I love your blog and you seem like an amazing teacher! :)
