## Always, Sometimes, Never: New Math Journal Topics

1. When you subtract, you have to count backwards.
1. When you add or subtract 10, the ones place digit stays the same.
1. If my ruler is broken, then I can’t use it to measure.
1. The person with the most coins has the most money.
1. If I want to make the largest 3 digit number possible, then the hundreds digit has to be the largest digit.
1. You can partition a rectangle in half four different way.

(For some reason I didn’t take pictures of their answers to this one)

7. If I have some coins with only 2 pennies, then the total amount will end in 2.

Most of the topics easily transitioned into investigative tasks that resulted in students creating posters with “proofs” to defend their arguments. I’m looking forward to creating more next year to use with my students!

I am a math teacher that LOVES mathematics and wants to continually improve to make math make sense to elementary students.

What a lovely way to have your students engage in the SMPs Christy. To see 2nd grade students write and record their mathematical thinking at the level you’ve captured here is super empowering! The MTBoS is definitely benefitting from you sharing your class happenings through this blog.

Thank you! My students know they can’t go to their math group of they don’t tell me why the wrote their answer, even if it’s wrong. I’ll have to take pictures of the next time we do it with posters. Maybe we’ll do one more before we get out of school.
