Fact Family Factory

2 min read

The Mission: 

Decode the bar model to find the missing factor or total, then construct the complete "Fact Family" of four related equations!


Math Skills:

  • Bar Modeling: Understanding the relationship between the total length and its equal parts.

  • Multiplication & Division: Solving for missing factors or products.

  • Fact Families: Recognizing that multiplication and division are inverse operations, allowing three numbers to form four related equations.


How to Play:

  1. Look at the bar model. Calculate the missing value (either the total at the top or one of the segments at the bottom) and type it into the flashing box. Click Check Model.

  2. The game will reveal four empty equation rows. Using the three numbers from the bar model, write out the complete Fact Family.

  3. You must construct two unique multiplication equations and two unique division equations.

  4. Click Submit Fact Family to verify. If everything is correct, confetti will fall, and a new problem will load!

式家族：解碼條形圖


任務簡介: 

解碼條形圖以找出缺失的因數或總和，然後建構出包含四道相關算式（兩道乘法、兩道除法）的完整「算式家族」！


數學技能:

  • 條形模型: 理解總長度與其等分部分之間的關係。

  • 乘法與除法: 解出缺失的因數或積數。

  • 算式家族 (Fact Families): 認知乘法和除法是反向運算，三個數字可以組成四道相關聯的方程式。


玩法說明:

  1. 觀察條形圖。計算出缺失的數值（可能是頂部的總數或底部的一小段），將其輸入閃爍的框中。點擊 「檢查圖形」(Check Model)。

  2. 畫面會展開四行空白的方程式。使用條形圖上的三個數字，寫出完整的算式家族。

  3. 你必須寫出兩道不重複的乘法算式和兩道不重複的除法算式。

  4. 點擊 「提交算式」(Submit Fact Family) 進行驗證。如果全對，畫面會飄落彩紙，並載入新題目！
