Unit 3 lesson 2&3 The Need For Algorithms- Creativity in Algorithms Day 25

Review Quiz 4 Journal vocabulary words/terms

Lesson 2- The Need for Algorithms Today- design an algorithm to find the minimum card in a row of playing cards. Then, presented with a more formal, "Human Machine Language" you try to implement the algorithm again, in the new language. Different algorithms can be developed to solve the same problem Different 'code' can be written to implement the same algorithm

Lesson 2- The Need for Algorithms Low level programming language: A programming language that captures only the most primitive operations available to a machine. Anything that a computer can do can be represented with combinations of low level commands. High level programming language: A programming language with many commands and features designed to make common tasks easier to program. Any high level functionality is encapsulated as combinations of low level commands.

Minimum Card Algorithm Activity Guide: Minimum Card Algorithm Write instructions to find the smallest card in a row of playing cards Compare solutions with classmates and come up with the minimal set of instructions needed to do this Define a "human machine language" for this task and implement your algorithm with it. Test out and refine your algorithm

Lesson 3- Creativity in Algorithms In this lesson you get more practice designing algorithms using the "Human Machine Language". In particular you see that new problems are often easily solved by combining other algorithms that you know. Introduce the 'swap' command, new to the Human Machine Language Design an algorithm for the "Min-to-Front" problem Activity Guide: Human Machine Language - Part 2: Min To Front
