The lesson for the 4th-grade class commenced with an introductory activity designed to engage the students. This activity encouraged them to utilize their knowledge of fractions and decimals within a practical scenario, notably concerning financial literacy. Subsequently, we revisited crucial topics such as transforming fractions into decimals, executing addition on fractions with denominators of 10 and 100, and executing comparisons between decimals. This revision was instrumental in solidifying the students' comprehension and equipping them for a forthcoming evaluation.

To aid in the conceptualization of complex mathematical ideas, we employed various visual resources, including grids, charts, and manipulative objects as part of our teaching materials. Linking symbolic notions with tangible visual aids allowed the students to cultivate a more profound comprehension of fractions and decimals.

The lesson further embraced cooperative learning and peer interaction by orchestrating pair-based activities. This setup facilitated a platform for students to exchange ideas and strategies, thereby enhancing their grasp on the taught concepts and abilities.

We provided a range of tools and resources, such as decimal place value mats, tenths and hundredths grids, scrap paper, sample number lines, and base ten blocks, catering to diverse learning styles and preferences. This approach guaranteed comprehensive support for all students, ensuring their academic advancement.

Throughout the lesson, I prompted students with complex questions to stimulate critical thinking, establish connections between mathematical theories and real-life instances, and foster problem-solving capabilities. We employed formative assessment techniques, like interactive questioning during tasks and the use of interactive slides, to assess students' comprehension and pinpoint any areas needing additional emphasis or reiteration.

The session concluded with a recapitulation using Pear Deck, enabling students to display their knowledge and reflect on their preparedness for the impending evaluation.

In essence, this lesson was structured to enrich the students' understanding of fractions and decimals, bolster their problem-solving aptitude, and set the stage for their success in the assessment, all while creating an affirmative and stimulating educational atmosphere.
