I’ve been doing math education in California since 1989. Math is a civil right ALL students deserve. I will occasionally post about my children or my chickens. #TapeDiagramTuesday #iTeachMath #RecreationalMath

Mark Twain probably didn't actually say this, but my job title is literally Director of Continuous Improvement, so I at least endorse the sentiment.
Dark olive quote graphic with oversized pale yellow quotation marks in the corners. Centered text reads “MARK TWAIN” and “Continuous improvement is better than delayed perfection.”

As I see it, the diagram of the gears seems to be suggesting that when we try to combine curriculum, leadership, and professional learning communities, then the gears won't work and the system comes to a standstill. Can we just fix the image please?
Three gears arranged too closely together that they will not actually spin. One gear is curriculum and assessment. The second gear is instructional leadership. Third gear is professional learning communities. As I see it, the diagram of the gears is unwittingly suggesting that when we try to combine curriculum leadership and professional learning communities, then there is gridlock and the gears won't work.

Today was supposed to be a day off when I joined a Zoom meeting a few minutes early. I mentioned that I am struggling with preserving my days off as actual days off…rather than filling them with meetings. She just kicked me off the meeting and said she will take notes for me. I needed that.

Screenshot that says…
The Ring Pro’s biggest hurdle is going to come from its steep entry-level cost. It retails for $479 with its charging case. The case is also sold separately for $100. The Oura Ring 4 starts at $349, but can be as pricey as $499 depending on what finish you choose. The Oura Ring 4 also requires a monthly subscription of $5.99, which amounts to about $70 per year.
