Instead of, “Is he passing?”

Let’s try, “Is he learning?”

Our conversation will never move on from the pass-fail construct, until our questions move on.

Let’s move on.

We can do better.

@melbrethour We can explicitly guide discovery toward the conclusions needed. Discovery need not be reinvention nor glacial-paced reevolution of ideas.

How would you count these bottles?

My initial thoughts/summary of tonight's Jo Boaler webinar: https://t.co/WwGPWxDmjN

A fun problem from openmiddle: Using the digits 1-9 each exactly once, create three 3-digit numbers where their sum is as close to 1,000 as possible. Here's why it's impossible to get exactly 1,000.

I have seen every single one of these become barriers for my algebra students of all ages.

"[Students] believe that the equal sign means the answer comes next. They've been trained that way throughout school." @BuildMathMinds #BuildMathMinds24 Untraining this later is VERY difficult. We have to be aware of what we're incidentally teaching.

Avoid "mathematical run-on sentences" (thanks for this phrase!). If you write 3+4=7+5=12, your work says that 3+4 is the same as 7+5 is the same as 12.

[Math Teacher Barbie @MathTchrBarbie]

Make sure you write 9=4+5, not only 4+5=9. Also make sure students see things like 7=7 to disentangle the equal sign from reliance on operations or "doing something" for its inherent meaning.

[Math Teacher Barbie @MathTchrBarbie]

Make sure you at least sometimes read equal signs as "is the same as." @BuildMathMinds #BuildMathMinds24

"Relational Thinking is using the structure of math & connections between numbers to solve problems." Algebra IS structure and relationships/connections. @BuildMathMinds #BuildMathMinds24

[Math Teacher Barbie @MathTchrBarbie]

Yaaas! "Algebra is _soooo_ much easier if you have built relational thinking so that when you look at things you can see relationships and not just always have to compute." Christina Tondevold at #BuildMathMinds24

@NCTM Cake, because it's my birthday! Happy for it to be a round one for pi, though.

@ShannonOlsonEd : "Our students are climbing a climbing wall, not a ladder." There's more than one path.

[Math Teacher Barbie @MathTchrBarbie]

@ShannonOlsonEd Loved this talk! Thanks! You hit just the right level with it (for me at least).

We cannot just hold up a model and assume that children see what we as adults see.

The math is not in the model.

The math is in the child’s head.

Did you know you can split the Algebra Tiles on Polypad? Can you figure out what will balance the bottom scale in this picture?
