Got this to keep my little guy learning over the summer, and it’s been a win. We do about 20 minutes a day, and he actually looks forward to it — which says a lot! The activities are the perfect mix of fun and educational, covering reading, math, handwriting, and little logic puzzles that make him feel like a pro. It keeps his brain engaged without overwhelming him, and I love that it feels like a confidence booster instead of a chore. Great for quiet time, car rides, or a productive break between play. Highly recommend for anyone wanting to sneak in a little learning before first grade kicks off.

Keeps Their Minds Sharp

Format: Paperback

Got this for my daughter to give her pages to do for homework each day during the last month of summer. She likes doing school work to begin with but it took me by surprise when she would take it upon herself to keep completing page after page by herself. She really likes this workbook. The instructions on each page are clear and easily understood for her. Perfect for the age group and grade.

Great practice for the summer

Format: Paperback, Format: Paperback

I bought this book to use with my son the summer between kindergarten and 1st grade. I love that it has a variety of topics it covers including spelling, sight words, reading comprehension, and a mix of math skills. My son loves the colorful pages and variety of activities. He also loves that there are stickers included for when he completes each page. Would absolutely recommend this, especially for reluctant/high energy learners.
