Puzzles! When I was a teacher I loved having puzzle time in my classroom. We could use easy puzzles on the tough days and tough puzzles on the good days. Work together or work alone. Pick a new challenge, find new pictures or sit with an old favorite.
When I become a mom I gravitated to puzzles right away for my daughters. I tried so many different brands and sometimes it felt like I was buying "throw away" puzzles. Until I found the brand Melissa and Doug. WIN! These are the most durable puzzles EVER.
With all the technology that is available today... it's old favorites, like puzzles, that can help us, as busy moms, keep our kids engaged, challenged and learning through trial and error.
