Here's a simple fix the sentences ppt and a reading activity.

For the reading activity, the file includes dialogues, a worksheet, and an answer key.  I printed the dialogues and put them around the room.  Then I gave each student a worksheet (included in the file) and we did one dialogue together as a class before turning them loose.  Then they went around the room and read the dialogues to fill in their worksheet.  I would recommend teaching them how to read bigger numbers (up to 999,999) before starting or changing some of the numbers to simpler ones (like nine hundred thousand instead of nine hundred ninety-nine thousand nine hundred ninety nine) if your students are low level.
