Develop a mathematical eye for observing a math class, regardless of the course level or advanced mathematical content. Are your students active mathematicians in math class? Are your students using the Mathematical Practice Standards to access the content standards, such as explicitly justifying their solution strategies? Explore the practice standards; understand their importance for exploring mathematical relationships; and assess instruction based on what students are doing during their math class using a specific walk-through tool; align these observations with your district selected evaluation tool, such as Danielson. Take away a walk-through tool created using Google Forms for observing a math class which will provide evidence to guide future professional development with your teachers.
