How to Play
- Roll the Dice: Get two numbers (e.g., 3 and 4).
- Create an Array: These numbers form a rectangle (3 rows of 4).
- Place It: Hover over the grid to find a spot. Green means safe, Red means blocked.
- Rotate: Use the rotate button to fit buildings into tight spaces ($3 \times 4 \rightarrow 4 \times 3$).
- Earn Coins: Every square unit equals 1 Coin!
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.
