Using Shift Functions (Textbook Page 210)

Objectives Understand and be able to apply the logical shift function. Understand and be able to apply the arithmetic shift function.

Exam Questions on this Topic 1) Write down the effect of carrying out an arithmetic shift left by two places on the eight-bit positive integer and state the effect of this operation on the number. [2] Jan ) Assuming overflow does not occur, what would be the effect of carrying out an arithmetic shift left by one place on a positive binary number. [1] Where do you think you fall on the Progress Scale?

Assessment Objectives (Outcome) Grade E/D Standard: Be able to understand how to perform logical and arithmetic shifts left and right and achieve more than 40% of the exam style question. Grade C/B Standard: Be able to understand and demonstrate how to perform logical and arithmetic shifts left and right and achieve 60% or more of the exam style question. Grade A Standard: Be able to understand, demonstrate and teach others independently how perform logical and arithmetic shifts left and right and achieve 80% or more in the exam style questions.

Learning the Methods (30 Minutes) Working in pairs: Learn the method you have been given and make notes of the method. Put together 5 questions you could ask to test the learning using this method. Teach your method to your partner so that they know how to use this method. Partner to make notes of the method. Use your questions to test their understanding.

On-Line Assessment(15 Minutes) Go to Enter room Complete quiz on your own

Stretch & Challenge Activity 1) Write down the effect of carrying out an arithmetic shift left by two places on the eight-bit positive integer and state the effect of this operation on the number. [2] Jan ) Assuming overflow does not occur, what would be the effect of carrying out an arithmetic shift left by one place on a positive binary number. [1]

Extra Work A teacher wants to teach her students how to use arithmetic shifts left and right and logical shifts left and right. Using a software of your choice create a teaching aid for the teacher and ensure your teaching aid tests the students knowledge.

Assessment Objectives (Outcome) Grade E/D Standard: Be able to understand how to perform logical and arithmetic shifts left and right and achieve more than 40% of the exam style question. Grade C/B Standard: Be able to understand and demonstrate how to perform logical and arithmetic shifts left and right and achieve 60% or more of the exam style question. Grade A Standard: Be able to understand, demonstrate and teach others independently how perform logical and arithmetic shifts left and right and achieve 80% or more in the exam style questions.

Objectives Understand and be able to apply the logical shift function. Understand and be able to apply the arithmetic shift function.
