Ordering objects, cards, pictures in order from smallest to biggest and biggest to smallest is a foundational math skill. Seriation is an important building block for other math concepts. This can be a very easy skill to practice at home. Let your little one put silverware, pots/pans, books, cups, boxes in order from smallest to biggest. Use questions to help guide them through the process. Which one looks a little bigger? What object do you think is next? Have fun with it! They did GREAT with this skill today!
