Pondering Place Value

Is it essential in mathematics to have a good understanding of Place Value.

Every number MEANS something. Every digit inside a number also has meaning. Here is an explanation from Math Is Fun:

Remember, “digit” is another word for “finger” (and “toe”). Most people have 10 fingers and 10 toes. When our number system was developed, it was developed, in part, using the fingers on our hands; thus, the reason we rely so heavily on 1’s and 10’s.

This is the video we watched in class to learn more about numbers and place value. You can watch the entire video if you like, but I think the parts that relate most to what we are doing are the first 3 minutes and the last 3 minutes. 

Here is a Place Value Chart from Mathatube that you might find helpful:


  1. Dear Mr. Pahl,
    I really enjoyed the algebra video because it’s silly but still a good way to learn a lot from it.


    1. Dear Tori,
      I think the algebra video was silly and funny too. Maybe you should ask Mr. Pahl if there is another math video that is silly and funny just like the algebra video.

  2. Dear Tori,
    Why did you like the algebra video? Did you learn anything from watching the algebra video? I need to know more about why the video was silly.
