Definitions

Dyslexia: A specific learning disorder characterized by difficulties with accurate and fluent word recognition, spelling, and decoding; Portland Cement: A type of cement used in construction that is classified into different types based on specific properties; Aggregate: Materials such as sand or gravel used in construction to provide bulk and strength to concrete or mortar; Slump Test: A test to measure the workability or consistency of concrete; Water-Cement Ratio: The ratio of the

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
