Today was some more discussion involving the base 10 system, and other base systems. This entire discussion is meant to encourage a deeper understanding of our own system, and how this system is used in mathematics. If you understand better how numbers are grouped and constructed, you are better equipped to manipulate them.
First we wrote down an example in our math examples notebook just like yesterday:
Next we played around with creating numbers in base ten, focusing on how they are made up of ones, tens, hundreds, thousands, etc.
Students made number on the Smart Board using ones, tens, and hundreds.
Then we talked about what the place values would be in a base 2 system.
Instead of ones, tens, and hundreds we would have ones, twos, fours, eights, etc
Students made some more numbers on the Smart Board using these place values.
We also took down a few more examples:
We finally ended the day by watching a short video about black holes. I do this because I would like students to have a bit of a better sense of scale as we begin talking about bigger and bigger numbers.
Please remember – quiz on Friday on base 10, and number systems.
You should know how to break a number down into it’s individual place value parts (in base 10 and in any other base).
You should be able to count a number of objects in base 10, as well as in a base given to you.
Have a good one,
