Marker Lid Sorting

Activity: Sorting marker lids by color

Learning Materials: assorted marker lids (any small item that comes in a variety of colors will work), cups for sorting (we use yogurt cups)

Directions:
1) Sort the lids by color
2) Count how many different groups there are

Extended Activities (when ready)
1)  Compare the groups with the most/fewest lids
2)  Count how many lids are in each group
3)  Sort the lids by size

Even further extension (older students)
1)  Chart on a graph how many colors are in each group
2)  Add two groups together
3)  Find the difference between two groups

N is sorting the marker lids by color

I let N choose which color some of the lids were as they could have gone in different groups.

Counting which group had the most.
