Sir Cumference and Lady Di discover "Fracton numbers" while purchasing cloth and cheese at the Fracton Faire. While two-fourths may seem like the same as one-half, in truth it denotes two parts of one-half, or two quarters of the whole. But the real mystery is the fact that items at the fair keep disappearing, and Sir C, Lady Di, and the Earl of Fracton must set a numeric trap for the thief, teaching an important lesson along the way about the comparative size of fractions.
Puns--both literal and visual--abound in this fun adventure story with beloved characters and a solid pedagogical foundation.

Join Sir Cumference and the gang for more wordplay, puns, and problem solving in the clever math adventure that introduces readers to  charts and graphs through an annual bake-off.

Sir Cumference and Lady Di need a baker to prepare a special dessert for the annual Harvest Faire. Two bakers compete to see whose dessert is most popular. When Pia of Chartres and Bart Graf have trouble keeping track of the votes their desserts receive, they each develop a better system. Pia places a colored candy around the edges of a pie dough (like a pie chart), and Bart stacks up cookie tins (making a 3D bar graph). When there’s a tie, the two chefs cook up a hybrid dessert just in time for the Faire. Puns–both literal and visual–abound in this fun adventure story with beloved characters and a solid pedagogical foundation.
