    This paper proposes a didactic sequence as a strategy to review content on fractions, aimed at the final grades of Lower Secondary Education, especially in light of the impacts of the COVID-19 pandemic. This proposal can be used both to review content lost during the remote learning period and to introduce the topic to students. The experience of returning to classes, after more than a year, highlighted the gap and limitation of content transmitted remotely, in addition to those that were not addressed due to limited time and social distancing imposed by the pandemic. Even with teachers' efforts to transmit as much content as efficiently as possible, it was perceived that it was not enough to ensure adequate continuity of learning. Given this scenario, teachers face the challenge of teaching a significant amount of content in a short period of time, aiming to reduce this gap so that students can progress in subsequent school years with more confidence in their learning. Therefore, this didactic sequence focused on teaching fractions in the final grades is proposed. Learning fractions is essential for several reasons. Firstly, fractions are essential for understanding and representing parts of a whole accurately, being useful in everyday situations and in areas such as mathematics, science, and engineering. Additionally, understanding fractions develops reasoning and problem-solving skills, requiring analysis, pattern recognition, and application of problem-solving strategies. In this didactic sequence, a fundamental method of teaching fractions is proposed, with the aim of enabling students to understand these concepts autonomously. The educational process will address conceptual interpretations of fractions, basic operations, problem-solving, and playful teaching strategies, aiming to promote effective and lasting learning

    The objective of this work is to present an alternative approach for primary school teachers who work with teaching mathematics, using the Colorado PhET simulator. The aim is to provide teachers with knowledge about the simulator, along with suggestions on how some concepts normally worked on in elementary and secondary education can be approached through the use of the simulator. The proposals include teaching the initial concepts of fractions, affine functions, quadratic functions and trigonometric functions using PhET. To optimize the presentation of content by teachers, didactic sequences were developed for each topic, in addition to the production of videos to assist in demonstrating the simulator’s resources
