1939 Mathematics in Action Book One (with Answers), Hart & Jahn, Vintage Book

This engaging pre-WWII textbook was designed for junior high or upper grade students learning real-world math. Topics include percentage, geometry, ratios, and problem-solving through everyday applications—like postage rates, design symmetry, and railroad shipping costs. A striking vintage cover makes this a standout piece for educators, math lovers, and collectors of early educational materials.

Overall good condition:

• Cover: marks/fading and wear at edges and corners (bumped)
• Spine: marks/fading and wear at ends
• Pages: wear typical for vintage school book with some writing/underlining, age marks, foxing, folded corners and small tears. Foxing, writing and/or prior owner name on pastedown and/or end papers. When flipping through pages, most all appear clean.
• Edges: age marks/brown spots/writing and darkening

Please see all pictures as well to help determine condition.
