Lesson Two - Loads of Codes
Objective: 1. The students will learn of a variety of coding methods that are used in today’s world to help us get along
2. The students will attempt to create their own number pattern code.Anticipatory Set: Bring in mail that has been sent with the bar code on it, bring in credit cards and a passport for demonstration and illustration.
Input:
Methods of Presentation: - discussion - demonstration - group work
Previous Knowledge - knowledge of the mail system and credit cards
Task Components
- TLW see how the all of the mentioned coding systems work - TLW work in groups to continue learning this information - TLW read sheets given out by the teacher explaining these methodsThinking Levels
- Knowledge: recall previous information
- Comprehension: be able to read and use information
- Application: will be able to tell if codes are valid
- Analysis: will be able to tell the difference between the codes
- Synthesis: attempt to code with own code
- Evaluation: complete worksheet given
Modeling
- Teacher will model the codes as explained in given sheets.
- Teacher will provide examples of valid and invalid codes.
Check for Understanding
- All students will test validity of codes in groups.
Guided Practice
- TLW complete in class worksheet of different codes
- TLW review handouts on own in class
Independent Practice
- TLW attempt to create own coding method using patterns of numbers.
