Start with two colors
Choose two colors that look clearly different. Ask the child to separate, name and match objects with the same color.
Add action words
Use words such as take, place, swap, arrange and repeat so language moves with the activity.
Build a short pattern
After sorting colors, make a simple pattern such as red-yellow-red-yellow.
End with the child choice
Let the child choose a favorite color and build their own arrangement as the closing activity.
