To identify a repeating pattern, look for a sequence of elements that repeats in a predictable way. For example, in a sequence of shapes, you might notice that the same set of shapes repeats every few elements.
When describing a repeating pattern, it's important to note the core elements that are repeating and the way in which they are repeating. This could be in terms of color, size, shape, or any other characteristic that is repeating.
Extending a repeating pattern involves predicting what comes next in the sequence. This can be done by identifying the core elements of the pattern and continuing the repetition.
You can create your own repeating patterns by choosing a set of elements and arranging them in a predictable repeating manner. This could be done with shapes, colors, numbers, or any other set of objects.
