Intro to Programming - Blockly

Module	Topics	Programming Skills
Talking to your Computer	Writing a simple program	Print a string Store things in variables Read input from the user
Calculating Things	Blockly as a calculator Data types	Use mathematical operations (+ - * / **) Use strings Find the length of a string Convert between numbers and strings Print out numbers and strings
Making Decisions	Making decisions with if statements Conditional operators	Use the if/elif/else control structure Understand the difference between assignment and comparison Make numerical comparisons using (> < = != >= <=) Use nested if statements
Manipulating Strings	Using and changing strings of characters	Check for substrings within a string Use strings in conditional expressions in if statements Change the case of a string Replacing parts of a string
Repeating things	String indexing Using for loops	String indexing Loop over the characters in a string Loop over a range of numbers Loop in steps Loop backwards
Using loops	More looping Data types	Sum numbers using a loop Understand the difference between floats and integers Looping over characters Checking the ends of a string
Looping in the unknown	Using while loops	Looping while something is true: while loops Stepping in while loops Infinite loops Reading multiple lines from the user Using counters Looping over characters When to use for vs. while loop Factorisation: worked example
Advanced looping	String slicing Flags	Finding a substring within a string Slicing strings Setting flags in loops
