Every year with kinders I use drawing people as my way to see how the kids are progressing.
The 2nd or 3rd project in the year I have students draw the best people they can without any pre-teaching. I use this to see if they are at a scribble stage, cookie people stage..... etc. The next class I ask the students to color in their people - I look to see who selects colors, who colors in, who colors over, who sticks with one color crayon.... etc.
Then midway through the year we draw people again. This time I ask them to draw people with their heads at the top of their paper and toes at the bottom. We do an example drawing where students help me fill in eyes, nose, hair, ears, mouth, fingers.... on and on. The students do another drawing and color the next class. I specifically ask students to pick colors on purpose and to color IN their picture instead of over. At this point most students have graduated past cookie people and have full bodies -- and most will color IN their picture, but many still pick random colors.
At the end of the year we read "Giraffes Can't Dance" and talk about how they know the animals in the pictures are dancing since the pictures don't move. It is really interesting to listen to kids try and explain what they see. After the book we have our own freeze dance party!!! I play different types of music and the kids dance around - when the music pauses so do the kids. I have them look around at how they are standing -- bent arms, bent legs, tilted heads....
Then I have the students draw people again - I ask them to draw at least one arm and one leg to be bent. Next class, just like before, students color IN with colors that make sense.
At this point in the year I am looking for better motor control, the ability to use their favorite color on shirts/pants/shoes instead of faces and hair.
