3rd Grade Lesson: Fraction Number Line Exploration

Children enter a fraction into a custom "walk:__" block, then see their sprite walk that fraction along the number line. They explore fractional values and distances on a number line.

### Activity Summary

Children enter a fraction into a custom walk:__ block, then see their sprite walk that fraction along the number line. Children explore fractional values and distances on a number line. The number line will show the divisions corresponding to the entered unit fraction. The sprite will take the number of steps based on the fraction blocks (each block results in one step). Children follow an exploration worksheet that guides them through the process of exploring new custom walk:__ blocks and sequencing in Scratch. Children create different sequences of instructions to make the sprite walk to a particular spot on the boardwalk. All distances are expressed in fractions. Children progress to a task to create a path to several different places in a pre-planned order. Finally, children explore the outcome when the blocks are placed in different orders.

### Math Connections

Children extend their understanding of fractions on a number line.

### CS Connections

Children build scripts with a small set of instructions. Children explore sequencing the blocks and breaking down a distance into smaller parts. They explore custom movement blocks.
