If your elementary student is having trouble learning the basics of ratio, try this hands on activity:
Fill several cups of water and give them food coloring in the primary colors. Let them experiment making new colors by adding varying "parts" together of the food coloring to see what happens.
Alternatively, you can use paints instead of the food coloring.
