Array City in Room 5

The dreaded times tables… or are they? There are plenty of ways to help us remember basic multiplication, which is required number knowledge for Year 5 and 6 students in the mathematics curriculum.

One way we tried was by making an array city. An array is the way a times table is structured and it always makes a square or a rectangle if correct. For example, 3x3=9 is a square shape with three along the top and three down the side. This is why 9 is referred to as a ‘square number’.

The rectangular arrays, such as 7x3=21, are ideal for being shown as windows in a building. Our challenge was to create a building where the windows represented a times table array, the product (answer) was shown at the top of the building. We could be as creative as we like.

Mine is 2 lines of 10 so it’s 20. - Shaun

Some of the windows are smaller but it is still four in each line. So 4 times 9 is 36. - Addison

Mine is a skyscraper with one line of 6. I think it is 3 times 2. - Jay

Some buildings needed renovations because their times tables array didn’t quite work out. It required problem-solving and some cheap alterations. The key competencies used here were definitely thinking and using language, symbols and text. It is great to see our colourful array of arrays lining the classroom wall.
