Smart son asked me as I was throwing in a load of laundry if we were going anywhere today. I replied that I wasn't sure, but likely not. He shouted cheers of delight and said he loved staying home best of all. That made me feel good. I do try to have fun with my kids when they are home. I like our home to be a place they love to be. So in case you need more summer fun ideas...
sculptures- yes just get some wood pieces, glass marbles (dollar tree is great for this) and some wood glue- still washable but much better than elmers for bonding. Smart son did his on a scrap of masonite and painted his. Smart baby very systematically worked on his on a canvas board.
Colored cookies- so easy and fun. I should have taken the picture yesterday before we were left with only 3. Simply take sugar cookie dough roll the balls in colored sugar and bake. no sprinkle shaking mess- just cool colorful cookies-- We did them in pink, blue, yellow, green, orange.
Jumping raisins/or dancing spaghetti whichever you prefer. Cup 2/3 way filled with water, 2-3T vinegar, 1 t. baking soda and raisins or spaghetti pieces- my kids watched with rapt attention for 15 minutes while they bounced up and down.
Glowsticks- seriously I found a place that sells 15 skinny ones for 1$- They are the perfect light sabers, secret weapons, lights for under the bed forts, incentives for extra good clean up. They keep them occupied forever and all for less than 10 cents a piece!
