For our district math week, we celebrated math thinking by taking it to the halls. Thanks to @stevewyborney.bsky.social Estimysteries and some WODB, all students had the chance to think more about numbers (and sports/celebrities) #RSDMathRocks

Loved the starting quote "What happens in the ones place happens in every place." And the sketches visualizing shifting tens 🤯
This is something I could utilize in groups tomorrow! #RSDMathIntervention
