First graders learn about artist Wayne Thiebaud and explore estimation, counting, and probability while creating an artistic masterpiece.

### Aaron M. Rumack

Reading mathematics problems can frustrate students to the point of shutting down. Although Pólya’s four-step plan is a well-known problem-solving framework, my students benefited from a more concrete and detailed approach: chunking the reading.

### Jon D. Davis

Design principles are used to construct and refine a technology-infused lesson for beginning algebra students learning about systems of linear inequalities.

Despite the importance of artificial intelligence in our daily lives, it has yet to be integratedinto K–12 classrooms in a meaningful way. Explore a lesson in which geometry students useEuclidean distance to implement a functional machine learning algorithm in Google Sheets™.

Within a single internet search, thousands of results occur when looking for a lesson or mathematics activity. However, the results are not all of good quality. We present a mathematics lesson planning protocol (MLP^{2}) to help process the search results and offer experiences of teachers using the protocol.
