Two different sets of numbers both have a mode of 10. What could they look like?
Why is it important to sort numbers before finding the median?
How can organizing numbers help us make better decisions in real life?
Math Talk:
Have a conversation about this image. Be curious. Be creative. Can you see in different ways?
What numbers and patterns do you notice? How do you see? How and what can you count?
What is the same and what is different between the two stem and leaf plots? How does the mode, median and range calculations help make sense of the numbers? How might handwritten data tell a different story than the calculator data?
