Wow, Thursday came fast : )
How do you remember to round?
I tend to think of it like a hill (a hyperbola perhaps?), or a half circle…
If you were a rolly polly bug and you roll into a ball each time you stop, which way would you go at the various points along the way?
1.1 through 1.4 end up back at 1 and 1.5 through 1.9 end up at 2. It is the same if you were to start at 0 and start going up in the ones place. 1-4 is rounded back to 0 and 5-9 end up at 10. Enjoy this freebie : )
I would love to hear how you teach rounding. Feel free to link up any math related post.
Have a happy
