For Parents

Newsletters describing math strategies, how they work, and their connections to algebra. Cards games to play at home are also provided.

Curriculum Units

Units for grades two through four. They are intended as an interim for teachers as they start to form a vision of how to take on their own curriculum design process. These are always being revised and reformatted. Adapting these to your own setting is essential.

What we do

Cognitively Guided Instruction (CGI) is a professional development research base that explores the teacher noticing practices of attending to children’s mathematical thinking, interpreting that thinking based on detailed developmental frameworks, and deciding how to respond instructionally based on that knowledge of the children (Jacobs et al., 2010). CGI based classrooms are language rich problem-solving environments where teachers elicit children's thinking in order to explore mathematical concepts and procedures. Based on the work of Thomas Carpenter and Elizabeth Fennema (2015), this over 30-year research base continues to explore the knowledge of how children’s number sense developments over time. The original research explored grades K-3’s understanding of the single digit operations in addition, subtraction, multiplication and division. That expanded to multidigit base ten development and invented strategies in the four operations, algebraic and relational thinking (Carpenter et al., 2003), and K-5 development of fraction and decimal operations (Empson & Levi, 2011). The research continues through the work of such researchers as Megan Franke (UCLA), Susan Empson (Missouri), Linda Levi (Teacher Development Group), Vicki Jacobs (UNC at Greensboro), Rebecca Ambrose (UC, Davis), Randy Phillipp (San Diego State), among many others of the next generation of researchers spread across the country. See the CGI bibliography (2013) for an updated list of research articles and publications.

Who we are

The first Cognitively Guided Instruction (CGI) professional development institute in Minnesota brought together seven teachers in 1993. The teachers banded together to form a grassroots effort bringing CGI practices and research to colleagues in their respective buildings and districts. With support from a two-year Eisenhower Title II grant, awarded by the Minnesota Department of Education, the seven teachers both maintained their connections and also began expanding the scope of their networks. James Brickwedde became the group's lead administrator due to his background in grants management prior to having become a teacher.

In 2000, the group entered into a formal relationship with Hamline University's Continuing Studies Program, establishing the Project for Elementary Mathematics with Brickwedde as the program coordinator. In 2011, the Project became a private entity as it currently exists.

Colleagues at other Minnesota school sites who have worked as CGI leaders are James Brickwedde (Project for Elmentary Math), Margaret Williams (Anoka-Hennepin Public Schools), Michael Wallus (Richfield Public Schools), Christina Miller (US Math Recovery Council), Sarah Johnston & Jill Bue (Roseville Public Schools).
