Median, Mode, and Range




We have started something new in math class! The mathematicians are learning about the median, mode, and range during estimation projects. We estimated on index cards this week, and then posted our estimates on the chalkboard. We were sure to sequence the numbers from least to greatest.
Then we calculated the median, or middle number. We started at the least and greatest numbers, and then worked our way to the middle.
Then we tallied the mode, or number repeated most often. This was easy to see visually with the numbers on the board.
Lastly we calculated the range, or the difference between the largest and smallest number.
Nice job, mathematicians! We will continue to calculate the median, mode, and range when estimating!
