The other day I gave my students a morning work sheet of adding different units of measure. One of the problems was 3 feet and 10 inches plus 4 feet and 5 inches. I showed my students how to add the inches and when they got the total of 15 inches they had to subtract the base unit 12 and carry 1 foot over to the feet column. As I was doing this I realized the base changed as the amount in each unit changed. For example if I was dealing with seconds and minutes the base would be 60. If the problem was days and weeks the base would be seven, interesting. I can relate to the subject of base in my fourth grade classroom this week.
