HIT- Great quick snack or added side dish with dinner. I could see many versions of this. Crescent Pepperoni Roll-Ups would be perfect for appetizers while watching football or for a girls movie night in.
Recycle old water bottles and grab some cheap pool rings. You could color the water like the rings too make a more challenging match/ring toss games for the older kids. Add glow sticks for night time ring toss
DIY Tic Tac Toe Game Board for kids- this would be easy to do for either gender. those pretty organza bags with the black sharpie lines and different colored glass stones from the dollar store :) love it!
Target Golf Game: Great indoor golf using a cardboard box for kids - great for a cold day! You can color them primary/ secondary/ tertiary and make a point value system with the holes being worth certain points, .Easy to make, lots of fun.
