Can you to help solve a multiplication question?
Which of these number sentences describe the array?
There may be more than one correct answer.
If we have a two-dimensional shape (2D), we can work out how much space it takes up (the area), by seeing how many unit squares fit inside the shape. In the video, you'll see how we do this, as well as how we can add up parts of unit squares.
Find the area of the shape below.
Let's look at how we can use arrays and multiplication to find the area, or how much space is inside, a two-dimensional (2D) shape, by counting how many unit squares fit inside it.
What is the area of the rectangle?
In this video, we use arrays to work out the area of our rectangle but start naming the dimensions as length and width.
Find the area of the rectangle shown.
selects and uses the appropriate unit to calculate areas, including areas of squares, rectangles and triangles
