Here's a cheap, easy and fun activity for your kids. Cut a pool noodle in half and then glue two sides of the cut noodles together keeping the inside of the noodles up. Decorate it however you please. Then prop it up on your stairs, using a chair or gluing it to a wooden box like the picture below. Use a clear organizing container as the marble catcher at the end. For summer time it's fun to fill it with water and you could even use food coloring to make the water a different color. Now your marble track is ready for racing!
All you'll need is some pool noodles, funnels, measuring cups or plastic drinking cups and tape (duct tape or packing tape should work or you could even find some suction cups to stick them to the walls).
