"When does it make sense to change [cultural] elements? When does it not?" @jennalaib.bsky.social shares 3 examples that explore this question. "It’s interesting to think about how these interact w/ student experiences, as we continue to make complex choices within our professional practice." 1
Session 1 of our Speaker Series, by @pamseda1.bsky.social, got Session 3's @jennalaib.bsky.social thinking: "When does it make sense to change [cultural] elements?... The answer isn’t a checklist or a directive. It’s a stance... I strive for intentionality & balance... Why this shift? & for whom?

Is a hot dog a sandwich? Is an elevator a vehicle? Is an emoji a word?
These ?s are a provocation. "We think we know what a vehicle, or sandwich, or word is, but we find our reasoning shifting as problematic cases arise. As a result, our implicit definitions become explicit & more clearly defined."

Making Sense of Word Problems

My 6yo asked me this morning:
"If 0 + 0 = 1, would 8 times 0 be 4?"
I wrote a blog post about it.

"I was surprised to learn that...my students felt strongly about not being told 'the answer'... One student wrote about the importance of having time to process the information and another wrote that listening to other students’ ideas 'helps me unstuck myself.'” - a G3 teacher #StudentReflection
We've heard similar things from elementary math teachers, about what they've learned from using our Student Reflection Tool over the course of the year!

Love this! How a child "stacks" the decks tells us so much about what they understand!
I often institute slightly bespoke rules to improve card games, but my very best one is my special rule for War:
For that game only, my kid can set up the decks (in size, composition, and order) however she chooses.
A tweak that greatly improves the enjoyment of all players
