Medieval Base 10 Practice
I never learned base 10 as a kid, or if I did, I have absolutely no recollection of it. I first learned about it when Baloo was in school for the first month of first grade. I was lost. Completely and utterly lost. I researched it, and while I can’t say I love the idea, I’ve learned to accept it and move on. This is what kids are being taught so I’m not going to fight it.
Baloo can be resistant to anything he thinks is learning, so I really like to cover-up the learning by making it look fun, or just making it cute. He was a bit star struck with the knights and dragons, so he didn’t mind doing this!
I gave him 3 little piles of tiles (should have stuck with 2 since we were only adding 2 numbers). Then I told him to put some of each in each of the 10 squares.
Then you count how many you have of the first one and put that number on the first line. Count the number of the second one and put it on the 2nd line. Then, since all the squares are full, you put =10 at the end.
And repeat!
Baloo finished the entire page! We did all 10s this time, but in the future we will mix it up with numbers 1-10, and I’m working on a base 20 version so we can do 3 addend problems as well!
You can download your own medieval base 10 and base 20 here!
I plan on including base 10 and 20 sheets in most of my upcoming packs, so keep an eye out for it with different themes!
Oh man, I pinned this to the wrong board, I guess I'll just have to pin it again……
FYI, the 20 grid is not a base 20. Base 10 refers to our counting system being based on 10, every time you reach 10 you head to the next set. So base 20 would be counting to 20 before any numbers repeated or you headed into a second digit. This is what comes of taking math for elementary teachers in college where she made us learn how to do all math functions in base 4 so we would know what it felt like for kids learning math for the first time.
And yes I just babbled way too much.
