The IMPACTS K-8 Program caters to teachers seeking to bring about the greatest change in students' mathematical experiences and improve student outcomes in mathematics. This includes classroom teachers, special education teachers, long term substitute teachers, coaches/interventionists, and others directly serving math learners.

IMPACTS Program Goals:

• Improve teachers' professional agency and confidence with conceptual mathematics instruction
• Improve students' mathematical agency and confidence
• Increase the use of student-centered instructional strategies

The program consists of 5 components:

• Teacher Workshops on Saturdays throughout the school year
• Summer Mathematics Institutes for Teacher Teams engaged in site-based leadership
• Site-based support for Teacher Teams by CRR staff
• Teacher Leadership Retreat for teachers engaged in regional/district leadership
• Mathematics Educator Appreciation Day Conference (MEAD)

During the school year, the CRR will offer workshops open to ALL Arizona teachers (see workshop descriptions below). These workshops introduce teachers to the big ideas of mathematics in grades K-5 and 6-8.

During the summer, the CRR will offer week-long institutes for teachers to who demonstrate productive mathematics dispositions, commitment to their schools, and the capacity to become school site mathematics facilitators. See Program Agreements for more details.

Information about the school year workshops will be advertised through the CRR listserv, so please make sure you are on the list.

For more information about the IMPACTS program or to form a Teacher Team, please contact Melissa Hosten (mhosten@math.arizona.edu) for K-5 or Rodrigo Gutiérrez (rodrigog@math.arizona.edu) for 6-8.

Description: This is a two-part workshop. The first part is a level one workshop, addressing the topic at a high and medium level. Part 2 is a Level 2 workshop, which will address the topic at a small and micro level. Teachers that attend both will develop a strong understanding of successful lesson structures and how to use any curriculum with these structures.

Part 1: What instructional frameworks help children learn mathematics most effectively? This is a question research has answered, but it is still a debate in many classrooms and in many circles. Part of the reason is that we do not have a strong sense of the different instructional frameworks, and part of it is because some frameworks seem “easier” than others. But are these easy frameworks effective? Are these frameworks also efficient? Should an instructional framework for mathematics be efficient? Come and experience two common instructional frameworks that rare often used with mathematics, and dig into the benefits and drawbacks. Experience an effective instructional framework and then unpack its structures.
Part 2 (April 27) will provide teachers additional experiences with an effective lesson framework and an opportunity to analyze their curriculum and find the ways their curricular lessons can be tweaked or revised to leverage effective lesson structures and an effective instructional framework.​​

Description: Geometry is the attempt to understand space, shape, and dimension. Within mathematics, geometry has been a source of great insight into other mathematical domains, such as algebra. Geometry enables students to represent and make sense of the world, analyze and solve problems, and represent abstract symbols pictorially to facilitate understanding. However, students are often asked to memorize geometric properties and formulas rather than to explore the underlying concepts through worthwhile tasks that involve hands-on experiences. 

Come join us as we explore the expectations for middle grades geometry, the progression of geometric thought through the van Hiele levels, and how to tailor instruction to provide the appropriate experiences for students to develop through the phases of learning.

Come and explore these ideas as we put the toolkits from Building Thinking Classrooms together in our final high school workshop of the year. This training is specific to High School classrooms and students.

It helps students understand such important ideas as ratios, proportional reasoning, percent change, negative numbers, expressions, equivalence, equality, similarity, and function thinking. This is why it is so important that middle school mathematics instruction builds powerful problem solvers by emphasizing conceptualization and meaning-making, not just formulas and answer-getting. Come join us as we explore conceptual teaching and develop tools to help you thrive in your classroom.

They are essential for proportional reasoning, algebra, and probability, yet they are incredibly difficult to learn and teach. In middle schools, it is important to understand students’ previous experiences with fractions in order to develop their algebraic reasoning. Fractions operations intentionally and systematically grow from work in 3rd grade, culminating in fluency with operations with rational numbers in 7th grade. How do we help students move along this path? What strategies will build the concepts clearly and understandably? How do we develop and integrate fluency while also addressing other middle school math topics? Come and explore the developmental path and strategies to move students to deeper understanding of fractions and fraction operations.
