Children solve a Fraction Number Line Mystery in which they read clues to identify a fraction on a number line. They use known CS concepts, such as repetition, and new Scratch blocks such as hide/show, go to, and wait.

Children solve a Fraction Number Line Mystery in which they read clues to identify a fraction on a number line. They invent their own Mystery project, use a storyboard organizer to plan each clue (with a drawing), and modify a Scratch program that uses each clue to solve the mystery.
Children locate fractions on a number line, including equivalent fractions with different denominators.
Children use known CS concepts, such as repetition, and new Scratch blocks such as hide/show, go to, and wait. The activities in this lesson require breaking a problem into smaller parts - decomposition.
