Roundingto the nearest
ten thousand & hundred thousand
• This presentation is a resource to assist with teaching students to read large numbers by identifying periods and place value.
• The lesson gives students only two answers to choose from. This reinforces the idea of a particular place value staying the same or increasing by one.
• There is opportunity to assess student understanding, so make sure students have pencil and paper (or math notebooks) available.
