Outdoor Arena: There are so many objects outside that will help reinforce this skill. Take any opportunity that you see to discuss volume, length, and width. Filling up buckets for washing cars, trash cans, or flower pots are all great for discussing volume. You can give your child a tape measure or ruler and ask them to measure the length of different objects and then compare which ones are longer or wider. Have them measure a variety of things. Skateboards, mailboxes, flower boxes, and cars are just some examples of things to measure. The possibilities are endless with this activity!
