Craft With Seashells
Seashells make a great craft because they are inexpensive (or free) and the options are endless. Your tots can paint them, string them, or stack them. The only thing needed is some glue and a little creativity!
Write a Summer Bucket List
Teach the kids about setting goals early on with a Summer bucket list. It doesn't have to be anything serious — friendships, new sports, or recipes — but it will be fun to check items off the list and turn to it for ideas when it feels like you're in the midst of an endless Summer. Consider making one at the end of the Summer too, heading into the school year.
Make a Slip 'n Slide
Oh the slip 'n slide! Whether you choose to homemake one  with plastic sheeting or purchase one  ($20), no child will turn this activity down. Try adding pool toys and setting it on a slight slope to increase the fun factor.
Make Designs With Body Paint
No need to head to the fair; have fun at home with body paint  ($7). Use a paint brush and glitter to draw their favorite designs.
Try a Bubble Paint Project
This time it's OK for your child to blow bubbles in her drink! With only a few ingredients you probably already have around the house, your tot will make beautiful and dreamy bubble prints  that turn into great book covers, handmade cards, or decorations for her room. Messy, yes, but that makes this project even more fun — and perfect for a sunny Summer afternoon!
Take a Hike
Head outdoors with a local hike. A scenic stroll is just the way they can get their energy out and explore good ol' Mother Nature. It's the perfect opportunity for teaching them about plants and flowers too.

A chalkboard wall gives your artists a place to draw without the worry — phew! Consider these creative ideas for chalkboard paint  and read this guide  before you get started.
Feed the Ducks
Pack up the kids, head to the park, and feed the ducks! With just a roll of bread, you and the kids are guaranteed endless entertainment, not to mention giggles. You can even make a half-day trip of it, packing a lunch and hanging by the playground.

Make Chalk Spray
Sure, the kids can play with sidewalk chalk this Summer. But why not switch it up a bit and let them spray their chalk. By simply mixing paint, water, cornstarch, and soap , they'll have a unique formula that's fun to spritz on the driveway and sidewalk.
Turn the Deck Into a Massive Game Board
Board games are a lot more fun when you can actually jump into them. The 36th Avenue  converted their deck into a game board with a giant pair of dice.
Make a Trike Car Wash
With little more than some PVC pipe and a garden hose, you can transform your driveway into a car wash for small tricycle riders.

Play Car Wash
A car wash is probably one of the few chores that can be turned into playtime. Get out the buckets, rags, and bubbles, and let them have fun with it. Reward them for their hard work with a few bucks or a trip to the candy store!
Create an Outdoor Science Lab
Science is fun but messy. So bring the lab outside in the Summer and let kids mix and spill to their hearts' content! This outdoor science lab  has everything kids need to start experimenting — beakers, test tubes, food coloring, and a ground ready to soak up the spills!

On a particularly hot day, fill some water balloons and place them in baskets throughout the yard. Then invite the neighbors over and inform them all of your water balloon fight.
Plan a Treasure Hunt
Pull out the pirate hats and send them on a treasure hunt. Make a treasure map by staining the paper with coffee and burning the edges. Then, have a prize — gold coins — hidden at the end of the journey. Watching their excitement will be just as fun for you as it is for them.
Play Sidewalk Sudoku
If your tot already loves the game of sudoku, put the pen and paper away and shut off the iPad because it's time to create a giant version for the driveway . Once other kids see your tot solving the puzzles, they'll be quick to join in the fun!
Set Up an Obstacle Course
Get the kids into a competitive spirit with an obstacle course. Using objects you already own (ropes, tubes, and beams), you can create a backyard course that tests their agility  and will keep them entertained for hours. It also makes an affordable party theme too!

If you live on a coast, nothing beats a day at the beach. Pack these essentials for the babe  and let the tots play in sand. Just don't forget the sunscreen!
No need to wait until Christmas; bake up these gooey sugar cookies  and let the tots decorate. Use cookie cutters, food coloring, and sprinkles to make each cookie unique.
Plant a Garden

Try Throwball Painting
Art and movement join forces when you start throwball painting . All that's needed is a box, some paint, and some balls. The end result is nothing short of colorful!

Your child will also explore color theory, seeing what happens when the primary colors (red, yellow, and blue) mix together! Doing this project outdoors makes cleanup as easy as a hose-down.
Go Fountain Jumping
Plan a day of visiting park fountains and splash pads to keep the kids cool. Each pad is different, providing tots with tons of different ways to play.

Put your little detectives to work with a scavenger hunt. This is a great activity for a group of kids, and you can set it up anywhere: park, backyard, house, or neighborhood. Keep it simple or turn to this detective party  for clues on how to set up a more elaborate adventure.
Camp in Your Backyard
No Summer is complete without a night of backyard camping. Pitch a tent, make s'mores, and tell campfire stories — no worry of bears necessary!
