The grade 4 mathematics textbook, part 2 of a series, delves into fundamental mathematical concepts with a focus on practical applications for fourth-grade pupils. Covering lines, angles, 2-D and 3-D shapes, time, length, capacity, mass, and graphs, the curriculum emphasizes hands-on learning. Students learn to draw and compare lines, create and measure angles using an angle maker, and explore the properties of 2-D and 3-D shapes. The textbook introduces time-telling skills using analog and digital clocks, and addresses the measurement of length, capacity, and mass with real-world examples. Additionally, it provides a foundation for data interpretation through the representation and analysis of graphs using pictograms and bar charts. This comprehensive approach aims to foster a holistic understanding of mathematical principles while promoting practical problem-solving skills.
