The graduated ruler is one of the first encounters students have with decimal numbers. This video for cycle 3 students (CM1, CM2, 6e) is an introduction to decimal fractions and decimal numbers. A decimal fraction is a division of one unit into a number of parts equal to a power of 10 (10, 100, 1000, etc.). A decimal number is a number that can be written as a decimal fraction. These concepts are complex and require a long work over the whole cycle 3. Viewing the video is obviously not sufficient and only constitutes an outline of these chapters.

We must then start from concrete situations. For decimal fractions, I recommend starting with parts or cut bands in order to realize that they are only partitions by 10, 100, 1000, etc. Using the ruler and lengths is also a way to manipulate decimals with palpable tools before entering conceptualization. Skill: – Produce and use various representations of simple fractions and decimals. – Use and represent decimals.
