### ⭐⭐⭐⭐⭐ Review
*by C***E on 20 March 2021*

This is a great workbook. It's very well layed out and clear to read. We did a couple of page of each topic each day when school were closed and it worked very well. My child enjoyed it so much so he'd often do two pages of each topic. We will continue to use this book and I Highly recommend it.
