Math Instruction PD Newsletter: Improving Math Teaching

Math instruction is one of the most frequently cited areas for teacher professional development because the gap between how most teachers learned math and how research says students best learn math is significant. A newsletter that communicates math training content clearly, gives teachers specific practices to try, and sustains momentum between training days is the communication work that makes math PD productive rather than episodic.

Ground the training in what students are doing and not doing

A math PD newsletter that opens with a description of specific student mathematical behaviors the training is meant to address is more compelling than one that opens with the training's theoretical framework. Students who can execute algorithms but cannot explain why they work. Students who quit when a problem does not immediately resolve. Students who can solve problems but cannot interpret their answer in context. Each of these is a specific, observable classroom situation that an instructional shift is designed to address.

Introduce one instructional routine clearly

Rather than summarizing an entire math PD day, the newsletter should focus on communicating one instructional routine with enough detail that teachers can implement it immediately. The Number Talk routine, where students solve a mental math problem and share their strategies aloud, takes 10 minutes and builds number sense without requiring any materials. A newsletter paragraph that describes the structure, gives a sample problem, and notes two common facilitation challenges is a complete teacher resource for that routine.

Explain productive struggle and why rescuing is costly

Many math teachers instinctively reduce the cognitive demand of a problem when students struggle, either by re-explaining the procedure or by simplifying the task. Research shows this pattern, known as the Initiation-Response-Evaluation cycle or funneling, prevents students from developing the problem-solving persistence that complex math requires. A newsletter that names this pattern, describes what it looks like in practice, and offers one alternative response to student struggle gives teachers a concrete tool for a challenge every math teacher faces.

Address the manipulatives and representation question

Many elementary teachers use manipulatives, but many secondary teachers view them as for younger students only. Research on mathematical representations consistently shows that moving from concrete to representational to abstract instruction supports deeper understanding at all grade levels. A newsletter that gives secondary teachers one example of how a physical or pictorial representation builds algebraic or geometric understanding more durably than symbolic manipulation alone makes the case without requiring a philosophical argument about math instruction.

Give specific mathematical discussion prompts

Teachers who want to increase mathematical discourse often do not have a specific enough repertoire of discussion moves. The newsletter should include five to ten academic language stems for mathematical discourse: "I agree with what [Name] said because..." "I solved it differently. My approach was..." "How did you decide to..." "What would happen if..." "Can you prove that..." Teachers who have these stems visible in their classroom use them. Teachers who received them once in a training and have to reconstruct them from memory do not.

Connect math PD to assessment practices

Math PD that focuses on instruction without connecting to assessment produces a gap: teachers implement new approaches but continue assessing the old way, which means the students who benefited from the new instruction are not being evaluated in ways that show that growth. A newsletter that notes how assessment should shift alongside instruction, for example, including open-response explanation questions alongside procedural items, helps teachers align the full instructional cycle rather than changing one piece in isolation.

Share a student work example

A brief, anonymized student work example that shows mathematical thinking made visible, including a student's written explanation of their strategy or a sketch of their problem-solving process, demonstrates what the instructional shift produces in student output. Teachers who can see what the goal looks like in actual student work have a target to aim for. A student explanation that connects a visual model to a symbolic procedure is a concrete image of what conceptual understanding looks like, and it is more persuasive than any description of what good math thinking should sound like.

Build in a teacher reflection at the end of the month

A single reflection question embedded in the newsletter at the end of a month of math PD implementation, for example, "Describe one moment this month when a student showed you mathematical thinking you were not expecting," collects rich data about implementation quality and produces teacher reflection that deepens the practice. Those responses, shared anonymously with permission in the following month's newsletter, build a community of math learners on staff.
