When extending a pattern, the core elements of a pattern are presented and children keep the pattern going.

At first, start from the left and ask children to extend to the right: ABCD | ABCD| _ _ _ _.

Later, try starting from the right and ask children to extend left: _ _ _ _ |ABCD |ABCD.

For an extra challenge, try a pattern with an incomplete unit. For example, ABCD | ABC_ | _ _ _ _ is harder to extend than ABCD | ABCD | _ _ _ _.

Another way to extend a pattern is to make beaded bracelets. You can start the pattern going, and children continue it over and over again until the string is full.

You can also try activities like building a block tower with repeating colours. You can get children started by beginning the tower or by providing a picture of a tower that they can complete.
