Week 10 The shepherd and his sheep
A shepherd with 6 sheep had 13 sections of fence which were arranged
into 6 pens of identical size and shape (congruent). The arrangement is
represented with 13 toothpicks shown on the board in your classroom. (Sorry,
I cannot create the picture for the teacher web page.)
One evening, someone stole one of the fence sections leaving only 12. After
thinking long and hard, the shepherd rearranged the 12 sections to form 6
pens of identical size and shape for the sheep.
Use 12 toothpicks to show how the shepherd made the six pens. This can be
done without any overlapping or cutting of any toothpicks. Glue or tape your
solution onto a piece of paper.
