You would that if they were coins that their parents were them to give away, which operation choose. Like most is tweak the more i.e. the addition. Let’s change the question. If you had to make the number of tasks that appear in the operations which would choose? They will obviously chose the subtraction. This may be a game very pedagogical.
Here again may be placed to test the teacher pedagogical tools. Teacher will show others that thoughts also transform or change. This will give way to the master to teach them through examples and tasks as physical things change and they can be measured through the numbers. Volume of bodies: The bodies have in b same volume, and this with regard to their matter and mass. For example the volume of a three-dimensional figure, is the number that indicates the portion of space occupied.
Expressed in cubic units. Water can express similar things since measured by fractions c.y. When we hear the expression been solid, liquid and gaseous. We can imagine and see how each one of them represents volumes of bodies. The solid state we can find him three dimensions and a derivative. Height, width, length and depth. To the liquid state properties we can find him in relation to the existing liquid class. Vapor pressure, boiling point, the heat of evaporation, heat capacity, the volume per Mole, the viscosity and compressibility. It also examines how these properties are affected by the temperature and pressure. The gaseous state, we can say that their elementary particles are less stable. And they are much faster. Course not in all cases. Since there are gases well below levels of movement, but at the moment we try those. That you are particularly affected by the pressure as a result of temperature. The master: The teacher will teach children to make figures of plasticine, cardboard and other elements.
