Array City: Building Multiplication Skills

Array City is a creative maths game that helps children visualize multiplication facts as geometric “arrays”. By building a city out of rectangular blocks, students develop a concrete understanding of area and the commutative property of multiplication.

How to Play

  • Roll the Dice: Click the button to generate dimensions for your building (e.g., 3 and 4).
  • Calculate Area: Multiply the numbers to find the area (3 × 4 = 12).
  • Place the Building: Hover over the grid to find a spot for your new 3×4 building.
    • Green: The spot is valid. Click to build!
    • Red: The spot is taken or out of bounds.
  • Rotate: Use the rotate button to flip your building from 3×4 to 4×3. This helps fit buildings into tight spaces!
  • Fill the City: Try to cover as much of the grid as possible without running out of space.

Maths Learning Focus

  • Arrays: Visualizing multiplication as rows and columns.
  • Commutative Property: Understanding that $a \times b$ creates the same area as $b \times a$.
  • Area: Calculating the space inside a 2D shape.
  • Spatial Reasoning: Planning where to place blocks to minimize gaps.
