ALGORITHMS AND PROGRAMMING - Timeline

     The first strand in each year's CS Standards is Algorithms and Programming.  The chart below provides a brief outline of the different concepts in terms of when they are introduced.  The key concepts listed under this strand, by year, would be:

Grade	Programming (Block/Text – based)	Sequence	Loop	Event	Conditional (If – Then)	Variables	Iteration	Other
K	Block or unplugged*	Yes
1	Block or unplugged*	Yes	Yes
2	Block or unplugged*	Yes	Yes	Yes
3	Block or Text	Yes	Yes	Yes			Yes
4	Block or Text	Yes	Yes	Yes		Store and process data and perform calculations on variables	Yes
5	Block or Text	Yes	Yes	Yes	Yes	different data types, including numeric and non-numeric data, and perform operations on their values	Yes
6	Block or Text	Yes	Yes	Yes	Yes	different data types, including numeric and non-numeric data, and perform operations on their values	Yes	combining control structures such as if-statements and loops
7	Block or Text	Yes	Yes	Yes	Yes	different data types, including numeric and non-numeric data, and perform operations on their values	Yes	combining control structures such as if-statements and loops including compound conditionals documenting programs
8	Block or Text	Yes	combining control structures such as if-statements and loops including nested conditionals and loops;	Yes	combining control structures such as if-statements and loops including nested conditionals and loops;	different data types, including numeric and non-numeric data, and perform operations on their values	Yes	create procedures with parameters combining control structures such as if-statements and loops including compound conditionals

* There are a number of options for introducing K-2 students to programming concepts.  Unplugged might include such devices as the Programmable Mouse, Blockly, or Ozobots.  A simple version of Scratch - Scratch Jr - is also available.  It is free and will run on most IPads and Tablets.
