1 FEEDBACK ON ASSIGNMENT 2
Question 1
Algebraic thinking
Strands of algebraic thinking:
Read the section on “strands of algebraic thinking” on page 324 of the prescribed book.
Then turn to the study guide and read carefully through section 1.1.2 (explaining
algebra) on pages 7 – 9. Four points are mentioned.
1.1 For each of those points, use your own words to show your understanding of that
point. (4)
• Point 1: School algebra develops out of arithmetic.
• Point 2: Word problems can be represented using informal/formal
mathematical symbols.
• Point 3: We can think of algebra as generalized arithmetic.
• Point 4: Algebraic thinking involves recognizing relationships between
numbers.
1.2 Provide your examples to illustrate each of the four points. (4)
See examples on pages 7 – 9 of the study guide
1.3 Discuss how algebraic thinking differs from arithmetic thinking. Use examples to
illustrate the differences. (10)
Answers may vary, including examples to illustrate the differences:
The distinction between arithmetic thinking and algebraic thinking lies in how one
approaches problems:
• In arithmetic thinking, the focus is on solving a problem,
• In algebraic thinking, the focus is on representing a problem

Question 2
Developing algebraic reasoning
Bridging the gap between arithmetic and algebra.
Read the section on “Bridging the gap between arithmetic and algebra” on page 19 in
the study guide. Do the following tasks 1 and 2 of activity 2.1.
