A7. “How do you know the answer isn’t 10?” #ElemMathChat

Oh I really love this one!! Been too long since I’ve been on Bluesky apparently. Beautiful!

You’re really welcome! I’m glad you like them.

Check the comments!! :) There are heaps more there.

Maybe talk through a couple of concepts and how different approaches would highlight different parts? My son (yr 11) recently pointed out that one approach would be good for getting through junior high school assessments but terrible for problem solving in Methods.

I’d make sure they were really familiar with excel. Also, if they don’t know about wolfram alpha then they probably should.

If if you were born in 1979 but haven’t had your birthday yet this year :)

This is so cool!!

These are the ones I’m taking. Looking forward to some new ones to do. :)

Well done! That is very cool.

Australian here. I work with hundreds of classes. The concepts teachers tend to be concerned about are:
K-2:
- Quantity (eg, the counters moved so there must be more, recounting their own fingers)
- subtraction
- place value

3-5:
- place value
- division
- fractions

6-8:
- same as 3-5, plus facts
