Mathematics For Intermediate Phase Teachers I (MIP1501) ASSIGNMENT 02
UNIQUE NUMBER – 178117
Closing date: 03 July 2025
Primary lecturer: Dr PE Rankweteke
Question 1 (36 marks)
1.1.1 Problem-Solving Level
Let x = number of marbles John had at the beginning.
He doubled them: 2x
Thabo gave him 3 more: 2x + 3
Total = 21
Equation: 2x + 3 = 21 Subtract 3: 2x = 18 Divide by 2: x = 9
Answer: John originally had 9 marbles.
To teach: Use bar models and visual aids to help learners understand the steps and
logic.
1.2 Historical Evolution of Numeration Systems
1.2.1 Early Evidence
Early humans used tally marks on bones to count.
Example: Lebombo bone with 29 notches.
Example: Stones to count livestock.
