G4 Mathematics practical activities
Learning history makes people wise, reading poetry makes people witty, and studying mathematics makes people prudent. During the joyful National Day holiday, our G4 students carried out the activity of “making your own one-liter container and playing with water”. The children made a one-liter measure, measured out a liter of water, and then played with it. The purpose of this activity was to help children build up the sense of one liter by visualizing this measuring unit. Our school attaches great importance to students’ hands-on ability, which is a conceptual work from concrete to abstract and then from abstract to concrete. In hands-on activities, children have experienced the process of knowledge exploration, grasped mathematical concepts, and mastered “true” knowledge.
Practice gains knowledge
First, one-liter measures were made with discarded water bottles. Children have made brand new measures from household utensils such as kitchenwares from their homes. This seemingly simple step can help students understand the concept of capacity with the help of water, and prepare for learning capacity and volume in the future.
The children then measured out one liter of water with their own handmade measures. In this way, they were able to improve their visual senses of liter and milliliter, and to understand the unit rate of liter and milliliter.
What could be done with a liter of water they got? The children showed their creativity: some boiled eggs and others used it to keep fish. In this process, the children could also estimate the capacity of some containers and thus develop a quantitative sense of space size.
Students understood the meaning of capacity in activities such as manipulation, experience, observation, conjecture and reflection, and noticed that mathematics is closely around. As a result, for these students, the intrinsic motivation to learn mathematics has been aroused, and the efficiency of learning has been improved. In this way, a way for students to explore the mystery of knowledge in mathematics has been carved out.
