輕鬆提升高計算小數的成績 | Effortlessly Boost Your Child's Decimal Calculation Grades
For students in Primary 4 to Primary 6, mastering decimal operations is often a significant academic milestone. Transitioning from integers to decimals not only tests calculation speed but also requires a crystal-clear understanding of Place Value. To help students overcome this hurdle, Great Harvest Education has combined seasoned teaching experience with modern technology to launch a brand-new, free online tool — "Decimal Master".
1. 無限生成的隨機題庫：告別「題海戰術」的枯燥 | Unlimited Random Question Bank: Say Goodbye to Repetitive Drills
永遠做不完的新題目：每次按下開始，系統都會即時運算，生成全新的 10 條題目。
杜絕死記硬背：數字組合千變萬化，迫使學生必須真正理解算術邏輯，而非依賴記憶。 涵蓋四大運算：學生可自由選擇 加 (+)、減 (-)、乘 (×)、除 (÷) 進行針對性特訓。例如孩子只有「小數除法」較弱，便可集中火力攻破弱點。
Parents often face a dilemma: exercise books are finished once completed, or children simply memorize the answers, losing the value of practice. "Decimal Master" utilizes Algorithmic Generation, which means:
An Endless Supply of New Questions: Every time you hit "Start," the system instantly calculates and generates 10 brand-new questions. No Rote Memorization: The number combinations are ever-changing, forcing students to truly understand arithmetic logic rather than relying on memory. Covers All Four Operations: Students can freely choose to focus on Addition (+), Subtraction (-), Multiplication (×), or Division (÷) to target their specific weaknesses (e.g., focusing solely on decimal division).
2. 三階段難度設計：由淺入深的學習階梯 | Three-Stage Difficulty Design: A Scaffolding Learning Approach
我們深知學習必須循序漸進。程式內建了 Level 1 至 Level 3 三個難度等級，這並非隨意分級，而是經過嚴謹的邏輯設計：
Level 1 (基礎熱身)：針對初學者。例如「一位小數」與「整數」的運算，數字較小且結構簡單，旨在建立信心，鞏固基本概念。 Level 2 (進階挑戰)：進入「兩位小數」運算。這是考試最常見的題型，考驗學生對小數點對齊（加減法）及位數移動（乘除法）的熟練度。 Level 3 (大師挑戰)：混合了不同位數的小數（例如：三位小數加兩位小數）。系統會嚴格控制數字長度（例如確保算式不會過長導致無法運算），同時提供足夠的複雜度來模擬高難度試題。
We understand that learning must be gradual. The program features three distinct difficulty levels (Level 1 to Level 3), designed with strict logical progression:
Level 1 (Basic Warm-up): Targeted at beginners. Involves operations with "one decimal place" and integers. Numbers are smaller and structures are simpler to build confidence and consolidate basic concepts. Level 2 (Advanced Challenge): Moves into "two decimal place" operations. This is the most common question type in exams, testing proficiency in aligning decimal points (addition/subtraction) and shifting decimal places (multiplication/division). Level 3 (Master Challenge): A mix of decimals with varying digits (e.g., adding three decimal places to two decimal places). The system strictly controls digit length to ensure questions are complex enough to simulate high-difficulty exam questions without becoming unmanageable.
3. 即時批改與精準回饋：家長的最佳助教 | Instant Grading & Precise Feedback: The Best Teaching Assistant for Parents
自動化改卷：學生輸入答案並提交後，系統會立即判定對錯。正確顯示綠色，錯誤顯示紅色。 精準的格式要求：小數題目最講究「精確度」。我們的 App 特別加入了 「四捨五入」指令 (Rounding Instruction)。例如題目要求「取至一位小數」，若答案是 4，學生必須填寫 4.0 才算正確。這種嚴格的判定機制，能有效訓練學生在考試中留意題目要求，避免因格式錯誤而失分。 詳細成績單：練習結束後，系統會列出所有題目的詳細清單，讓家長一眼看出孩子錯在哪裡（是運算錯誤？還是四捨五入錯？），便於進行檢討。
For busy parents, marking math homework every night is a heavy burden. "Decimal Master" solves this pain point instantly:
Automated Marking: Once students submit an answer, the system immediately judges it. Correct answers turn green; incorrect ones turn red. Strict Formatting Requirements: Decimals require precision. Our App specifically includes "Rounding Instructions." For example, if a question asks to "Round to 1 decimal place" and the answer is 4, the student must enter 4.0 to be correct. This strict mechanism effectively trains students to pay attention to question requirements in exams, avoiding marks lost due to formatting errors. Detailed Report: After the session, the system lists a detailed summary of all questions, allowing parents to see at a glance where the mistakes lie (calculation error? or rounding error?), facilitating effective review.
4. 友善介面與多語言支援：隨時隨地學習 | User-Friendly Interface & Multi-Language Support: Learn Anytime, Anywhere
為了讓學習無障礙，我們在使用者體驗 (UX) 上下了不少苦工：
繁/簡/英 三語切換：無論您的孩子就讀中文小學還是英文小學，或是來自不同背景，都能一鍵切換介面語言，無需擔心看不懂數學術語。 手機/平板全支援：介面採用響應式設計 (Responsive Design)，字體大而清晰，輸入框專為手指觸控優化（特意隱藏了容易誤觸的上下箭頭）。無論是在上學的巴士上，還是等待興趣班的空檔，拿出手機就能進行 5 分鐘的高效特訓。
To make learning accessible, we have put significant effort into User Experience (UX):
Tri-Lingual Switching: Whether your child studies in a Chinese or English medium school, you can switch between Traditional Chinese, Simplified Chinese, and English with one click, ensuring no barriers with mathematical terminology. Mobile/Tablet Optimized: The interface uses Responsive Design. Fonts are large and clear, and input fields are optimized for touch screens (we specifically hid the up/down arrow keys that often cause accidental changes). Whether on the school bus or waiting for a class, students can grab a phone and complete a 5-minute high-efficiency training session.
