Common misconception
Children may find it difficult to comprehend that e.g. 1,200,000 may have a digit '2' in the one hundred thousands place but is actually composed of 12 hundred thousands.
Even though the digit in the 100,000s place is a 2, the number 1,200,000 is composed of 12 hundred thousands because one million is composed of 10 hundred thousands.
