The kind of representation our area math leaders deserve!
🔹🔹🔹
The objective of this organization is to establish a robust collaborative network that offers regular meetings and valuable professional learning opportunities for all elementary and secondary math leaders in the Houston-area. Through an established network, we can effectively use our voice as a community of math leaders in state and regional-level decisions.
By having frequent, predictable meeting times, organizations such as TEA and Region 4 can easily involve the group's input, influence and expertise in instructional decisions. We aspire to cultivate strong relationships among math curriculum leaders across the city and surrounding areas, ensuring a collaborative and enriching environment for all involved.

We can't wait to connect, collaborate & create!
