The Mission:

Solve four-operation math word problems by constructing "bar models" out of train tracks. Set up the tracks correctly to find the missing value and let the train pass!


Math Skills:

  • Four Operations: Addition, Subtraction, Multiplication, and Division.

  • Bar Modeling: Visualizing word problems using block lengths.

  • Equation Building: Translating real-world scenarios into mathematical sentences.


How to Play:

  1. Read the math word problem displayed at the top of the screen.

  2. Use the interactive tools to adjust the train tracks so they represent the math problem. (If you use the wrong tool or get stuck, a red Hint text will pop up to guide you!).

  3. Once the track is structured correctly, input the final calculated answer into the text box.

  4. Click Submit. If correct, the train will drive across the tracks, and you will advance to a new question!

鐵路建築師：條形圖解碼


任務簡介:

透過用火車路軌拼湊「條形模型 (Bar Models)」，來解答四則運算應用題。正確設置路軌以找出未知數，讓火車順利通過！


數學技能:

  • 四則運算: 加法、減法、乘法和除法。

  • 條形模型: 使用方塊長度將應用題視覺化。

  • 建構算式: 將現實生活情境轉換為數學算式。


玩法說明:

  1. 閱讀螢幕上方顯示的數學應用題。

  2. 使用互動工具調整火車路軌，使其能夠表達這道數學題。（如果你用錯工具或卡住了，紅色的 「提示」(Hint)文字會彈出來指引你！）。

  3. 當路軌結構設置正確後，將你計算出的最終答案輸入到文字框中。

  4. 點擊 「提交」(Submit)。如果答對了，火車將會駛過路軌，你也能繼續挑戰新問題！
