Because most of the students visiting Pioneer Sholes School are in the third grade, the multiple levels of arithmetic study typically achieved in a one-room school are less distinct than at the turn of the last century. However, to carry out the multiple level plan already laid out for reading and spelling instruction, the teacher can once again divide the class into three reader levels and assign work from the photocopies of antique text books kept at Pioneer Sholes School in the bottom of the book case in the back of the room.

Goal:  To study the concept of the number twelve as a whole number and as a product of its fractional parts.
