Ep 43 - P2 teachers are MATH TEACHERS too!
Duane and Cole uncork a crucial conversation about why educators working with our youngest learners—preschool through 2nd grade—must embrace the title “math teacher” with the same pride they claim “reading teacher.” They unpack the regrettable disconnect that leaves many early-years classrooms brimming with alphabet charts but light on number talk, then spotlight compelling research showing that strong early-math foundations outshine early-reading skills as predictors of later literacy success. We talk about creating joyful opportunities for play-based learning to nurture numeracy between ages 3 and 8 as the hidden catalyst for lifelong learning.Join us in this conversation.RESOURCES…✚ Count, Play, Explore https://www.countplayexplore.org/ ✚ Play-based Learning in the Early Childhood Mathematics Classroom: Culturally Sustaining Play: https://cornerstone.lib.mnsu.edu/icitl/vol2/iss1/2/ ✚ Early Math Collaborative: https://earlymath.erikson.edu/ ✚ Future conference dates: https://www.cmcmath.org/conferences REGISTER FOR OUR CONFERENCES:✚ Register for CMC Central P-2 Conference on August 2, 2025.

Ep 42 - Cole has us thinking about TRUST in mathematics
Cole ask us: Do leaders TRUST their teachers to implement ambitious instruction? Do teachers TRUST themselves mathematically? Are we asking teachers to trust their parachute or trust their light switch?It is well known that teachers need to have deep, flexible, and fluent thinking about mathematics in order to fully prepare their students for higher-order learning in later grades. Providing teachers with this kind of math understanding so they can then improve the quality of their teaching will require all partners in the math ecosystem to TRUST one another.

Ep 39 - Duane remembers to press record. Then he complains.
We talk about the featured speakers who are already lined up to speak at our symposium in March, 2026. The we announce our P2 Conferences which is a series of conferences throughout California specifically targeting preschool teachers through Grade 2. They are indeed MATH teachers…and they deserve their own math training.Then Duane complains. Cole and Scott listen.Duane shares that he is currently being treated for skin cancer. The procedure the doctor is employing is significantly improved compared to the treatment Duane would have received 10 years earlier. How do we apply this to math teaching? The California Mathematics Framework hopes to update teaching practices…but how do we get this knowledge into the hearts and minds of teachers?RESOURCES…✚ Nominate yourself or another CMC member to serve on the CMC state or section boards:https://docs.google.com/forms/d/e/1FAIpQLSfnIBTFGVT_CKsz5L8LbvEzkCLPekoe7GKEMxG7v1xOrfgNIA/viewform✚ Commision on Teacher Credentialing https://www.ctc.ca.gov/educator-prep/program-standards ✚ 2024 CALIFORNIA STANDARDS FOR THE TEACHING PROFESSION (CSTP):https://www.ctc.ca.gov/docs/default-source/educator-prep/standards/2024-cstp.pdf?sfvrsn=62eb3cb1_12 ✚ Listen to our webinar with guest Dionne Aminata: https://youtu.be/f9QFHBqLul0✚ Apply to speak in Asilomar.

We talk about stuff the night before the symposium. We also talk about "magic" teaching that excites and engages teaching. This "magic" is not magic at all. It is a set of replicable and spreadable skills that ALL teachers can learn and apply in their classrooms to excite and energize students into becoming curious and brilliant mathematicians.RESOURCES…✚ Future conference dates: https://www.cmcmath.org/conferences Please take a moment to read Chapter 2 from the framework!✚ California Mathematics Framework Ch 2: Teaching for Equity and Engagement https://www.cde.ca.gov/ci/ma/cf/Register for our conferences:✚ Register for CMC Central P-2 Conference on August 2, 2025.
