Use the table feature of a word processing program to create the basic chart. Use 10 vertical rows, with one cell for each finger. Make one horizontal row for each child in your class. Add an extra row at the top and the left side for names and labels.
Type each child's name in one cell in the horizontal row.
Type an identifier for each finger, such as thumb, ring finger or pinkie, on the first vertical row.
Print the chart in black ink.
Open nontoxic, washable-ink stamp pads or pour a few golf-ball-sized puddles of tempera paint onto a palette or paint tray. Place the ink or paint on a covered table.
Invite the children to come up to the table. Help each child to press her fingers, one at a time, into the ink or paint. Cover the entire fingertip.
Help him to press his fingers, one at a time, onto the correct space on the chart. Set the chart aside to dry.
Hang the chart at child's eye level. Give each child the chance to examine her own print as well as those made by classmates. Discuss what the prints look like and how they are similar or different.
