When I was a student teacher, one of my best teachers always said you have to use the text as a pretext. This is very important in a country, Spain, where most teachers use textbooks to teach their lessons. Yesterday, I found it easier than ever to implement his teachings.
I was teaching Natural Science to 5th grade students and I read the following definitions :
"All living things are made up of tiny units called cells. A cell is the
smallest possible living unit. Cells are the building blocks of life."
" Cells that carry out the same function group together to form tissue. Muscle tissue, for example, is made up of many muscle cells grouped together."
"Tissues group together to form an organ. Organs, such as the heart, contain different types of tissue which work together to perform a particular function."
"An organ is a collection of tissues joined in a
structural unit to serve a common function"
"A group of organ systems working together form an organism. An organism is a living thing."
