When I was looking for Spanish immersion materials for math - there were none!!! So I am making my own. I use these every day in my classroom. I will be posting more throughout the year.
If you want to see an example of my work, check out my freebie in my store. It's in English but you'll get a sense of how the pages go.
This is a SmartBoard (Notebook) document to help your Spanish language learners learn 4.NBT.5. It covers how to use the distributive property along with expanded form to multiply 3 digits by 1 digit.
If you use GoMath - it is aligned with Chapter 2 Lesson 7.
I hope that my work can be helpful for you. :)
