SET of 2 - Discovering Geometry: An Inductive Approach 2nd Ed - Student Hardcover [PD-2106] + Teacher's Guide and Answer Key [PD-2105] (Michael Serra, Key Curriculum Press)

Good condition, two volumes, sold together as one complete course. STUDENT HARDCOVER: kept under a clear plastic protective sleeve, so the boards beneath show only minor surface wear and scuffing on the front, with moderate scuffing and some whitish rub marks on the back. Binding solid and square, text block tight. Interior clean with no highlighting and no heavy writing, with one exception named plainly - a student left light pencil sketch work on the page facing Exercise Set 2.5, confined to that spread as far as can be seen. All colour photographs, diagrams and Escher artwork present and clear. TEACHER'S GUIDE AND ANSWER KEY: the paper cover has taken the harder life of the two, with significant creasing across the front, scuffing, edge and corner damage, light soiling, and a small circular sticker at the upper right. Its spine is worn but intact and the binding is sound. Its interior is clean, with no highlighting and no writing seen, and the answer key and lesson material are complete and legible. Pages are three-hole punched as issued. Thin paper shows faint ghosting from the reverse side, a printing characteristic rather than damage. Neither volume carries library stamps, pockets, spine labels or barcodes.…
