CCSD Math Leadership

@CobbEMCEdu @cobbemc We appreciate your support and look forward to another great competition in 2027! 👏

It was a joy for @cobbemc to sponsor the 2026 Cobb Math Tournament! You can count on Wattson being there next year too!

Congratulations to all who competed in the 2026 Cobb Math Tournament! 🎉 Your problem-solving and perseverance were on full display! Check out our 1st place ES & MS individual winners and teams!

Liquid volume conversions in math by: •Identifying smaller units that can fill larger units •Ordering units within a system from smallest to largest •Identifying the best unit to measure an item. Today was a messy visual 😊 @CobbMathDept @d_lanilovesmath

For our math warm-up, students chose if they wanted to solve mild, medium, or spicy problems. @PickettsMillES @CobbMathDept @d_lanilovesmath

Thank you for collaborating with us! Our teachers can find these resources linked in the CTLS PL Community in the Mathematics section. If you were unable to attend, a recording has been posted there too. 😁👍 reach out to @d_lanilovesmath or @emilyecf for more support.

This year’s CTLA math cohort experienced the vertical progression of area and started their Thinking Building Classroom book study. What a fun filled full day of learning! #CTLA @d_lanilovesmath @emilyecf

Getting new resources for your 360 classroom and using them immediately in your classroom…yes please! @d_lanilovesmath @CobbMathDept

We had a great 2 days hosting the CCSD math department for two trainings on 360 boards! It was fantastic to see all our 2nd-5th grade teachers in action, participating in walkthroughs and showcasing their students' work at the boards. @CobbMathDept @duewest_es #DWTheBestInTheGame

2nd graders used Cuisenaire rods to explore matter. They counted and added to see how the same blocks filled the same number of spaces no matter how they arranged them. @EastSide_CCSD @cobbscience @CobbMathDept

It’s been great working with middle and high school teachers learn more about 360 math classrooms. I’m happy they got to see it in action and experience it as a learner. Allowing them time to collaboratively plan for it was great next steps. @CobbMathDept

Doubles review on our 360 thinking boards are way cooler for second graders! 🤗 @NPKEagles @CobbMathDept

@d_lanilovesmath has been training teachers the past couple of weeks on 360 math classrooms in K-5. We are so glad you enjoyed it!

I had the opportunity to attend the Math 360 training at Due West Elementary. I enjoyed visiting classrooms and learning new strategies to implement in my instruction. #lifelonglearner @CobbMathDept

@CobbMathDept took teachers at Daniell MS on a data exploration with their Milestone data. Achievement Level Descriptors are great resources for moving the needle of students’ abilities.

@DebruynLauren had an engaging PL session for 2nd grade math teachers, charting course clarity! 😃👍

@d_lanilovesmath charted course clarity with 3rd grade math teachers. Look at those 360 math boards and magnetic manipulatives in action!

CTLA Math Cohort enjoyed learning more about the warehouse and are excited for the manipulatives to use in their classroom! #CTLA25
