HARRIET HIPPO AND THE MEAN GREEN
The kids use fractions to stop Hacker from spreading a virus that makes cyber citizens act mean.
Hacker infects Motherboard with a new virus -- one that causes her to make cyber-citizens act mean. Digit and the kids go in search of an antidote: 2/5 of the Electro-Root, 2/8 of the Healing Stone, and 1/3 of a box of Hacker's wig gel -- a strange antidote indeed! Will the young cyber-heroes be able to gather the ingredients and figure out how to properly mix these odd fractions before it is too late? The Big Idea: Fractions that look different can represent the same portion of a whole. Math Topic: Equivalent Fractions.
