<p>Title of Book: Sir Cumference and the Sword in the Cone Author: Cindy Neuschwander & Wayne Geehan (Illust.) Publisher (Date): Charlesbridge (2003) ISBN: 9781570916007 Grade Levels for Recommended Use: 3-5 (Ages 8-10) TEKS: (1) Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. (B) Use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution. (C) Select tools, including real objects, manipulatives, paper and pencil, and technology as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems. (D) Communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate. (7) Geometry and spatial reasoning. The student uses attributes to identify two- and three- dimensional geometric figures. The student compares and contrasts two- and three- dimensional geometric figures or both. (A) Describe attributes (the number of vertices, faces, edges, sides) of two- and three- dimensional geometric figures such as circles, polygons, spheres, cones, cylinders, prisms, and pyramids.</p><p>Brief Summary: King Arthur has issued a challenge. The first knight to find the sword, Edgecalibur, will be the next king. Young knights Radius & Vertex are on a hunt to find the sword, which has been hidden in a geometric solid somewhere on the castle grounds. They attempt to decipher a riddle the King has scribed on parchment. Will they unravel the riddle of Edgecalibur and inherit the throne? Materials needed: Book: Euler’s Formula 3D Geometric Sir Cumference & Geometric Net Chart Shape Handout The Sword in the Handout (Printable) (On The Board) (Printable) Cone</p><p>Math Journals Scissors Pencil Clear Tape</p><p>Suggested Activity: 1. Read Aloud  Read up to page 9 2. Geometric Nets  Pass out the Geometric Net Handout.  Distribute one (or two) shape nets per table/group – (Use Cube, Pyramid, Rectangular Prism, Triangular Prism, Cone & Cylinder).  Have students cut out geometric shapes and assemble.  Review faces, edges, and vertices vocabulary. 3. Read Aloud  Read pages 10, 11, 12 4. Euler’s Law  Have the Euler’s Law Chart posted on the board for students to come up and fill out. – Alternately have it posted on the SmartBoard and have students fill it in digitally.  Have students count the faces, edges and vertices of their assigned shape. – One person from each group should come and fill out their portion of the Euler Chart  Review the numbers presented in the book (page 12) – What do you notice about the shapes? – Do all the shapes follow Euler’s Law? – What shapes are Vertex and Radius looking for? 5. Read Aloud  Read pages 13, 19 - 25 6. Cone Conundrum  Have students calculate the heights of each of the four-presented cones if they followed Euler’s Law (3 x diameter). Compare results with the length of the shovel (48 inches). - Have students guess which cone holds Edgecalibur. – 3 x 24 = 72; 3 x 36 = 108; 3 x 21 = 63; 3 x 17 = 51.</p><p>References/Websites: Neuschwander, C.
