The Bulldozer Leveler: Visualizing Mean
- Feb 8
- 2 min read

The Mission:
The construction site is uneven! Some piles of dirt are too high, and some are too low. Your job is to find the perfect Average Height (Mean). You must set a "laser level" so that the excess dirt from the high piles perfectly fills the gaps in the low piles.
Math Skills:
Arithmetic Mean: Understanding "Average" as a process of redistribution or leveling.
Balancing Data: Learning that the total amount above the mean must equal the total amount below the mean.
Estimation: Visually estimating the center value of a data set.
How to Play:
Analyze the Piles: Look at the different heights of the dirt piles.
Set the Level: Tap or click anywhere on the screen to set your Laser Level line.
Check the Balance: Look at the top stats:
Excess (Red): How much dirt is above your line.
Gap (Blue): How much empty space is below your line.
Match Them: Adjust your line up or down until the Excess equals the Gap.
Bulldoze: Click the CHECK button. If you are correct, the bulldozer will move the dirt to flatten the ground perfectly!

推土機平整大師:平均數視覺化
任務簡介:
建築工地凹凸不平!有些土堆太高,有些則太低。你的工作是找出完美的 平均高度 (Mean)。你需要設定一條「雷射水平線」,讓高處多出來的泥土剛好能填滿低處的空缺。
數學技能:
算術平均數: 理解「平均」是一個重新分配或拉平的過程。
數據平衡: 學習平均線之上的總量必須等於平均線之下的總量。
估算: 視覺化估計一組數據的中心值。
玩法說明:
分析土堆: 觀察不同高度的泥土堆。
設定水平: 在螢幕上點擊以設定你的 雷射水平線。
檢查平衡: 查看頂部數據:
多出 (Excess - 紅色): 你的線 上方 有多少泥土。
缺少 (Gap - 藍色): 你的線 下方 有多少空位。
配對: 上下調整你的線,直到 多出 的數量等於 缺少 的數量。
推土: 點擊 檢查水平 (CHECK) 按鈕。如果你是對的,推土機就會移動泥土,將地面完美整平!
