Concept
We already learned how to "smash" a ten-rod. Now let's do it with huge numbers.
π― The Bank Exchange Rates: * 10 Ones = 1 Ten. * 10 Tens = 1 Hundred!
Example 1: "How many Tens are in the number 40?" * Cut off the zero at the end! * Answer: 4 Tens.
Example 2: "How many Hundreds are in 30 Tens?" * 10 Tens makes one Hundred. So 30 Tens makes... * Answer: 3 Hundreds! (Or the number 300).
You are just sliding the place values up and down the chart.
