Mass, Capacity, Temperature - Measure mass kg - Presentation

In the educational resource focused on measuring mass, students delve into understanding the difference between grams and kilograms. The lesson begins with a discussion on the concept of 'kilo' and its meaning, setting the stage for a series of engaging activities. The first activity challenges students to determine the mass of beans displayed in images, with weights marked in kilograms. They must use addition to find the total mass and also deduce the mass of individual cans. This exercise not only reinforces the concept of mass but also provides an opportunity to compare the weight of a gram versus a kilogram.

Subsequent activities involve estimating and measuring the mass of various objects, including bags and people, in kilograms. Students are encouraged to think about which unit of measurement is appropriate for different scenarios and to estimate before measuring actual weights. Another activity compares the weights of suitcases, enhancing the students' ability to compare and reason with mass. The resource further explores the concept of mass through reasoning exercises where students calculate the mass of barrels and boxes based on given relationships and differences. Independent work tasks require students to find and calculate the mass of objects, promoting critical thinking and application of the concepts learned. Throughout the lesson, key questions and vocabulary are provided to facilitate discussion and deepen understanding of measuring mass in kilograms.
