Let's Do Math to PIECES!
using the book, PIECES: A YEAR IN POEMS AND QUILTS


Guess How Many?

Some of these are easy, but some are hard. How many can you answer?
Make a guess, then count, add, multiply and subtract to find out. 
Let's start counting:
  • How many quilts are in the book, including the cover?
    • Did you know I cheated?  I only made one quilt for “Nose Knows” and “Mirage”.
    • Can you see what I did to trick you into thinking it is two quilts?
  • How many different geometric shapes can you find in the book?
    • Can you name them?
    • Do you know a name that would include all the others?
  • How many of the quilts use geometric shapes?
  • How many don’t?
Let's count triangles:
  • How many quilts have at least one triangle?
  • Which quilt has the most triangles?
    • Can you figure out how many?
  • Which of the quilts with at least one triangle has the fewest triangles?
    • How many does it have?
  • The Pieces quilt has lots of triangles and is very hard to count. You might want to print out the coloring page of this quilt.
    • Still too hard? Cut the quilt into sections. Figure out the number of triangles in each section, then add them together.  This might be a good project to do as a team. 
Let's count squares:
  • How many quilts are made mostly with squares?
  • How many quilts are made only with squares?
  • How many quilts have squares as part of the design, including the borders?
  • How many have squares ONLY in the borders?
  • Which quilt do you think has the most squares?
    • Why do you think that?
    • Are you counting the partial squares that you can see all around the edges of “To Each His Own”, “Nose Knows” and “Mirage”?
  • I can think of two ways you could find out how many squares are in each quilt.
    • Can you think of two ways?  More than two?
    • What would be the easiest way for you?
  • How many squares in all do you think are in all twenty the quilts I made for this book?
  • How many squares are inside the book?
    • This is tricky because of the places where parts of quilts are used in the front and back pages.  Also some of the borders are copied from the quilts. I didn’t make them, and don’t forget about the quilt that’s a cheat.*  (Let’s just leave out the squares that show in the photographs at the end, shall we?)
  • How many squares are on the cover?
  • How many squares are in “Encore”?
    • If I added another row all the way around how many squares would that be?
    • If I added two rows all the way around how many would that be?
  • Are there more squares or more rectangles in the book?
    • Why?
  • Are there more quadrangles or more rectangles?
    • Why?
Most and Least:
  • Of the quilts that are NOT made with squares, which one do you think has the most pieces?
    • Be careful.. Sometimes the quilting lines can make one piece look like more than one, and sometimes one fabric looks a lot like it's neighbor so it looks like one piece when it's two.
    • Why did you choose that quilt?
    • Do you think it has more or less pieces than the quilt with the least number of squares?
    • Do you think it has more or less pieces than the quilt with the most squares?
  • Which quilt do you think has the least number of pieces? 
    • Why did you chose that one?
Total:
  • Can you estimate how many pieces of fabric are in all twenty quilts I made for this book?
    • I’m going to include all the borders in my count.  Can you see how some of the borders are made with 4 pieces of fabric—2 across the top and bottom and 2 on the sides? Some have 8 pices in the borders.
Your turn:
  • Can you make up your own math problems about the quilts?
    • PS: Maybe you could make up some problems and give them to your friends.
    • PPS: Be sure you know the answers!
  • Want to know my answers
  • Do more math to Pieces...
