Overview
The kid hunts for things in nature that match a color. It is the fastest hunt to win, which makes it the right first one for toddlers and preschoolers. Hand them a color and a bag and they will fill it. Expect 15 to 20 minutes of focused searching, longer if you run several colors.
How to Do It
Pick two or three colors that actually exist in your yard or park. Green and brown are everywhere; red, yellow, and purple show up in flowers and berries. Hand the kid a bag and name the first color: "find me three green things." For pre-readers, give them a paint chip or a square of colored paper to hold up against what they find, which makes the matching concrete and self-checking.
Let them decide what counts. A kid holding a yellow square up to a dandelion is doing real visual discrimination. When the bag has a few of one color, switch to the next. Step back and let them range; your job is to name colors and confirm matches when they ask, not to find things for them.
Tips & Tricks
The paint-chip trick is the lever that makes this work for the youngest kids, because it turns an abstract color word into a side-by-side match they can do alone. To stretch it, ask for shades: "find a darker green than this one." To keep it going, dump the finds and sort the whole bag by color on the grass at the end, then count each pile.
Variations
Easier, for a toddler: one color at a time, you carry the bag, and you accept any reasonable match. Harder, for an early-elementary kid: a rainbow run where they must find one thing for every color in order, or a "two things that match exactly" challenge that forces close comparison. For Simba's age, make it a point-and-fetch game with one color and big, safe items so nothing small goes in his mouth.
