Ever wonder how much weight it would take to level out a see-saw? The free PBS KIDS Measure Up! App helps teach kids ages 3 to 5 the measurement skills needed for this and other real world measurement questions through a series of games, video and activities. PBS KIDS Measure Up! lets kids explore measurement concepts as they visit the “Lost Lagoon” featuring characters from popular PBS KIDS shows DINOSAUR TRAIN, PEG + CAT and SID THE SCIENCE KIDS, and connects to the PBS KIDS Super Vision companion app for parents.
