Great summer workbook
Format: Paperback
This book is a great tool to use over summer break to prevent loss of learning. I have been using this book with my 2nd grader for a few weeks and he enjoys the short lessons. I would prefer the lessons have a few more questions to cover each lesson.

Great way to support summer learning!
Format: Paperback
I absolutely love the Summer Bridge Activities: Bridging Grades 3–4! This workbook is a fantastic way to keep kids engaged and learning over the summer break. The activities are well-designed, fun, and educational, providing the perfect balance between reinforcing what they’ve already learned and getting them excited for the next school year. The layout is visually appealing, with colorful pages and interactive exercises that make learning feel like play.
What I appreciate most is how it covers key subjects like math, reading, writing, and critical thinking skills in bite-sized chunks that kids can easily manage. My child enjoyed doing a little bit each day, and I noticed significant improvement in their confidence as they completed each activity. It's great that this workbook also includes helpful tips for parents to guide their kids through the exercises.
Overall, this is a must-have resource for parents looking to keep their children sharp and engaged during the summer while still having fun. Highly recommend!

Great for growing minds!
I love these workbooks! We used to buy these at a local store until it closed. They help kids retain what they learned in school over the summer. The worksheet usually takes 5-10 minutes a day.
