Ideal for Summer Learning
Format: Paperback, Format: Paperback
The books are made of good quality and are durable for daily use. The pages are colorful, and the text is a good size for children to read. The instructions are clear and cover a wide variety of topics to reinforce children during the summer.
I would like for it to explain some concepts and not just be exercises. It includes answer sheets for all exercises, stickers to reward each day of exercise, and a diploma upon finishing the book. The exercises are designed for 15-20 minutes daily and are meant for children to review every day.
The pages are thick, so even if they use markers, it won't bleed through to the other side. I highly recommend them to avoid the summer gap when returning to classes.

Good book for summer!
Format: Paperback
I always get my son a workbook for that summer gap between grades, just so he doesn’t forget what he has learned and to get a little head start for the next grade. I usually get another brand but decided on this one and it is so great! Had the same exact material my son learned in second grade so it was easy for him to get in the groove of things and eases him into the next grade
