Since the 8 in the Tens box indicates 800, it must jump over the wall into the Hundreds box.. It means 8 × 100 = 800.

It is not always as easy or practical to draw boxes to determine place value and it can take a lot of time. There are three other methods to do the same without drawing boxes. Use the number 368.
Write down where each digit would go, without drawing the blocks.
METHOD 1
3 Hundreds + 6 Tens + 8 Units METHOD 2 3 × 100 + 6 × 10 + 8 × 1 METHOD 3 300 + 60 + 8 These three methods are called expanded notation. When we write a number in expanded notation, we break down a number to show the place value of each digit.
Expanded notation ‘shows’ place value
You will now learn more place values, namely THOUSANDS, TEN THOUSANDS and HUNDRED THOUSANDS. The methods and rules you studied in Grade 4 remain the same. Study the example. © Optimi
