I like to create curricular materials based on experience with a group of kids, not before. Recent work with 3rd graders and Turtle Art suggested that many kids were having trouble with part-whole relationships and procedurality. I asked kids to use the turtle to draw Halloween images. A few kids made recognizable images out of geometric shapes. Most did not.
So, I was inspired to create this Turtle Art activity in which procedures/stacks of blocks are provided and the students are then expected to assemble a complete image
The shapes used in this jack o’lantern are crappy enough that some kids will wish to improve upon them. The use of squares at an angle as eyes, cause children to see the geometry of shapes in new ways.
