Now do this put-the-text-back-together activity.
This is the text (if you need help).
Zimbabwe's central bank scrapped the country's currency to use the U.S. dollar. The Zimbabwean dollar became worthless because of hyperinflation. This peaked at 500 billion per cent in 2008. Since then, Zimbabweans liked the security of the U.S. dollar. Around 90 per cent of the economy uses the U.S. dollar. People have until September to change their local currency. The exchange rate is one U.S. dollar to 35 quadrillion Zimbabwean dollars.
Zimbabwe's old dollar will not disappear. The large number of zeroes on the bills is making them a collector's item. A 100 trillion Zimbabwean dollar note is selling online for US$35. This is over one hundred times more than the 40 U.S. cents the bill is worth. One hundred trillion is one plus 14 zeroes. One Zimbabwean is making money from the old currency by selling it to tourists. He said it was a waste of time to cash it in at a bank.
Back to the Zimbabwe currency lesson.
