It’s very helpful to have a reference on the wall!

This is a beautiful display that looks good in any Math Classroom! Most teachers print it on card stock, laminate it, and keep it for years. These posters will come in handy every year.

#### Implied ones can baffle even the best of them. When you can’t see them, they are easily forgotten.

Don’t let your students leave their invisible ones behind!

I was inspired to create Invisible Math when my students were combining like terms, so it was crucial that they recognized those invisible 1’s.

I created Invisible Math five years ago. It didn’t get much attention until last fall – in autumn of 2018 Invisible Math went VIRAL on Instagram, and now it’s on the wall on thousands of math classrooms across the world.
