Like GoMath but don't like their digital materials? I made my own to help my kids stay engaged. Each Notebook file page comes with a learning target that is easily changed to meet your exact wording. Many of the lessons include a Marzano-aligned vocabulary study page.
Don't use Go Math? These are still great for you as they are driven by the standard.
Let this Smartboard presentation help you teach your whole class or small groups how to write fractions in simplest form.
There is a short formative assessment included at the end. I LOVE not having to create the fraction models that morning or as I'm going along. It's SO EASY when it's already saved for you! :)
Check out my freebie to see if my work will work for you. I use these every day in my classroom.
