Origami, is not only a fun and creative pastime, but it also serves as an excellent instructional tool. The folds and creases allow one to examine a variety of mathematical ideas, including ordinal numbers. The children used the ordinal numbers as they worked their way through each fold of their origami boat. The children not only created a paper boat but also strengthened their understanding of sequencing and ordering. So, the next time you go on an origami trip, remember to sail over the waters of mathematics with ingenuity and curiosity.
