An introductory lesson on vectors

1. Bell work Express a as a column vector Express b as a column vector Express a – b as a column vector Extension: Draw the vector a - b in your book. What is the magnitude of vector b? a b

3. Reminder How would you draw a vector of magnitude 6cm and direction 235? If I label the above vector a, describe to me in detail how to draw -a What about 2a?

4. Reminder If vector a is (- 4) and vector b is (- 2) what ( 6 ) (- 3) is the column vector for a + b? a - b What about 2a – 0.5b?

5. Input a Tell me something about these vectors…. For any non-zero value of k, the vectors a and ka are parallel K is called a scalar, it has magnitude only.

6. Input OA = a AB = b Express OC in terms of a and b A B C

7. Activity Exercise 35D page 573 Odd numbers Exercise 35E

8. Review/ Plenary Write in your book up to three things you need to remember about today’s lesson Write down one thing you are not clear about and would like to go over again Finally, write down a number from 1-5 suggesting how well you met the learning objective.
