The Application and Optimization of Unit Integration Teaching in Primary School Mathematics Based on Big Ideas

"Big ideas" serve as a pivotal concept that occupies a central position in mathematics, connecting various knowledge points within the mathematics curriculum. The unit integration teaching of primary school mathematics based on big ideas leverages the structural framework of the discipline, facilitating students to actively construct knowledge through deeper understanding. Interviews revealed that while most front-line primary school mathematics teachers recognize the value of unit teaching under the big ideas framework and understand its basic process, challenges remain in determining unit teaching objectives, selecting appropriate teaching content, and formulating effective evaluation methods. Therefore, from the perspectives of teachers, schools, and educational research departments, specific strategies have been proposed to optimize the integration of primary school mathematics units based on big ideas.
