## Overview of Lessons

Getting Started with Programming

### From ScratchJr to Scratch

Students will be able to navigate the basic interface of the Scratch editor to create a simple program.

### Introduction to Computer Science and Scratch

Students will be able to define important computer science vocabulary and create a simple program in Scratch.

### Skills Practice: Sequences

Students will be able to create multiple parallel sequences.

### Skills Practice: Events

Students will be able to use event blocks to cause code to run.
Coding in Math

Students will be able to use loops in to repeat commands and add multi-digit whole numbers based on place value.

### Multiplication and Conditionals

Students will be able to create a program that uses "if/then" conditional blocks to review multiplication.

### Classifying Shapes by Category

Students will be able to create a program using events to categorize quadrilaterals based on their properties.

### Measuring Lengths

Students will be able to use events to create an interactive measurement game that has a user measure lengths with a ruler marked in fourths and plot the data on a number line.

### Animating Sprites with Multiplication

Students will be able to use multiplication to animate sprites with loops and wait blocks.

### Fractions and Variables

Students will be able to represent fractions on a number line using variables and conditionals in Scratch.

### Unit Fractions with Variables

Students will be able to use variables, loops, and reporter blocks to create a model and show how adding unit fractions is equivalent to multiplying unit fractions by whole numbers.
Coding in Science

### Balanced and Unbalanced Forces

Students will be able to describe how balanced and unbalanced forces impact an object’s speed. Students will be able to model forces in Scratch using conditionals and variables.

### Nutrition Maze

Students will be able to describe the benefits of healthy foods and will use conditionals to create an interactive nutrition maze game.

### Weather and Climate

Students will be able to use climate data and event blocks to predict and model typical weather conditions for a specific month.

Students will be able to explain how adaptations help animals survive in their habitats by creating an interactive program using events.

### Classifying Rocks

Students will be able to use if statements in Scratch to classify rocks based on the Mohs Hardness Scale.

### Modeling Life Cycles

Students will be able to program a model of the stages of a frog’s life cycle using broadcast message events.

Coding in ELA

### Random Sentence Generator

Students will be able to generate random numbers in Scratch to create simple sentences with nouns, adjectives, verbs, and adverbs.

### Creative Storytelling

Students will be able to plan and animate a story using events and sequences.

### Animating Poetry

Students will be able to break a poem into sections to understand literal and metaphorical meanings and create an animated reading of a poem in Scratch.

### Nonfiction Animated Recordings

Students will be able to use events to create a clear, animated reading of a nonfiction text.

### Punctuation Game

Coding in Social Studies

### Communities Adapt to & Modify their Environment

Students will be able to use click events to create a scene that shows how communities adapt to or modify their environments.

### Digital Vocabulary Flashcard Quiz

Students will be able to use variables and conditionals to create a vocabulary quiz that changes each time it is taken.

Students will be able to identify elements of culture as they create a cultural choose-your-own-adventure game.
More Coding Lessons & Projects

### Skills Practice: Costumes, Backdrops, and Animations

Students will be able to use costume changes to animate sprites and use broadcast messages to change backdrops.

### Skills Practice: Scratch Drawing Tools

Students will be able to create customized sprites and backdrops using the drawing tools and program sprites using the color sensing blocks.

Students will be able to use broadcast events to trigger action between sprites in a program.

### Skills Practice: Repeat Loops

Students will be able to use repeat loops to run a sequence of code multiple times.

### Skills Practice: Forever Loops

Students will be able to use a forever loop to animate a sprite.

### Skills Practice: Variables 1

Students will be able to create and use variables.

### Skills Practice: If/Then Conditionals

Students will be able to create a program using if/then conditional.

### Skills Practice: If/Then/Else Conditionals

Students will be able to use an “if/else” conditional in a program.

### Digital Greeting Card Project

Students will be able to create a digital greeting card that uses loops and events.
