Reseña del libro "Alyannah's Math Adventures (en Inglés)"
Dr. KD hands it to Alyannah with one rule: she cannot open it until she holds 24 river stones. Every stone she earns carries a single letter, and only when all 24 are in her hand will the message be revealed. In Alyannah's Math Adventures: The River Beyond, Grade 7, Alyannah and her friends Sofia, Andres, Priya, and Jayden, along with Rosa, a new classmate who asks "How do you know?" about everything, travel beyond the Rio Grande on a loop through New Mexico. They find unit rates at Eagle Nest Lake, write proportional equations on the rim of Capulin Volcano, measure percent error beside real dinosaur tracks at Clayton Lake, and add and subtract negative numbers at Ute Lake and on old Route 66. They solve equations in the Valley of Fires, write inequalities among the petroglyphs at Three Rivers, and make scale drawings at the Salinas Pueblo Missions. Then they measure circles at El Rancho de las Golondrinas, sample trout in the Red River, and head home to Taos for the Council of Chances, where the last stone is placed and the envelope is finally opened. Every one of the 24 stops includes: - Two illustrated story pages with a real problem and a real resolution - "Friends Who Think Differently," showing several strategies for the same problem - The River's Lesson: a clear explanation, a picture model, a worked example, and new math words - Alyannah's River Journal, with her own reflections, a Field Note about the real New Mexico place, and a tip from Dr. KD's Chalkboard - A King Frog Hop Riddle and a multistep Challenge Box - Three illustrated, leveled Math Labs (Warm-Up, Keep Going, and Challenge), fifteen questions in all - A full answer key, a Try It At Home activity, and a full-page Visual Story Back matter includes ten extra practice questions for every stop with answers, a Grade 7 Standards Map, a bibliography, an index, and a certificate of completion. The book is aligned to the New Mexico Grade 7 Mathematics Standards (the Common Core State Standards as adopted by New Mexico). It covers unit rates with fractions, proportional relationships, percent problems, operations with positive and negative numbers, repeating decimals, linear expressions, equations and inequalities, scale drawings, triangles and cross sections, circles, angle relationships, area, volume and surface area, random sampling, comparing populations, and probability. It is written for seventh graders, homeschool families, classroom teachers, and tutors. One stop per week covers the school year. Every place in the book is real, and every place hides a real Grade 7 idea. What do the 24 letters spell? Follow the river to find out. Dream it. Plan it. Solve it. Achieve it.
