K to 12 - Grade 8 Math Learners Module Quarter 2Nico Granada
Here are the completed statements based on the conclusions:
1. n(A × B) = n(B × A).
2. A × B ≠ B × A.
The key conclusions are:
1. The cardinalities of the Cartesian products A × B and B × A are equal, since n(A × B) = n(B × A).
2. However, the sets A × B and B × A are not equal, since the ordered pairs will be arranged differently, so A × B ≠ B × A.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

16. a. (1) No: Needs a new symbol for each new power of ten.
(2) Sort of: The value of each numeral is 10 times the value of the previous numeral.
(3) Sort of: By decorating each basic symbol, you now have one basic symbol for each place, the
number of dots on the symbol varies.
(4) No.
(5) Sort of: though, given the origin of this system, it would be more likely to be counted. For
example, 2 thousands, 8 hundreds, etc. However, technically, you would multiply the value
of each basic symbol by the number of dots on the symbol.
(6) No zero.
b. It has characteristic 2: The value of each place is 10 times the value of the previous place. It "sort
of" has characteristic 3, with the modification that each "place" contains two symbols. Some
might say that it has characteristics 4 and 5, but the order of the numerals is still a matter of
convention – unlike base 10, where changing the order changes the value.
c. This system has all characteristics.
17. a. 585 cartons of milk
b. It has all 6 characteristics because this system is essentially base 6. The places are called cartons,
boxes, crates, flats, and pallets. The value of each place is 6 times that of the previous place.
18. 1:0:58:4 or 1 hour, 58.04 seconds
19. The child does not realize that every ten numbers you need a new prefix. At ―twenty-ten‖ the ones
place is filled up, but the child does not realize this. Alternatively, the child does not realize the cycle,
so that after nine comes a new prefix.
20. The child skipped thirty, because he or she does not think of the zero in the ones place as a number.
The child counts from one to nine and starts over. In this case, the child has internalized the natural
numbers (N), but not the whole numbers (W).
21. Yes, 5 is the middle number between 0 and 10
22. Because the Hindu-Arabic system has place value and a place holder (zero, 0), it allows extremely
large numbers to be represented with only 10 symbols. It is also much less cumbersome, since it only
takes six digits to represent one hundred thousand.
23. We mark our years, in retrospect, with respect to the approximate birth year of Jesus Christ—this is
why they are denoted 1996 A.D.; A.D. stands for Anno Domini, Latin for ―in the year of our Lord.‖
Because we are marking in retrospect from a fixed point, we call the first hundred years after that point
the first century, the second hundred years the second century, and so on. The first hundred years are
numbered zero (for the period less than a year after Jesus’ birth) through ninety-nine. This continues
until we find that the twentieth century is numbered 1900 A.D. through 1999 A.D.
24. In our numeration system every three digits have a different name, such as thousands, millions, and
billions.
25. Place value is the idea of assigning different number values to digits depending on their position in a
number. This means that the numeral 4 (four) would have a different value in the ―ones‖ place than in
the ―hundreds‖ place, because 4 ones are very different from 4 hundreds. (That’s why 4 isn’t equal to
400.)
26. If we use 2 feet as our average shoulder width, and we use 25,000 miles as the circumference of Earth,
we have 25,000 miles 5280 feet per mile divided by 2 feet per person = 66,000,000.

35. This has to do with dimensions. The base 10 long is 2 times the length of the base 5 long. When we
go to the next place, we now have a new dimension, so the value will be 2 2 as much. This links to
measurement. If we compare two cubes, one of whose sides is double the length of the other, the ratio
of lengths of sides is 2:1, the ratio of the surface area is 4:1, the ratio of the volumes is 8:1.
36. a. Just as each of the places in a base 10 numeral has a specific value that is a power of 10, each of
the places in a base 5 numeral also has a value, but in a base 5 numeral these values are powers of
5. Let’s look at this diagram:
5
125 25 5 1
53
52
51
50
We can see that the places of a base 5 number, starting from the right, have the values 1, 5, 25, and
125. Now we ask ourselves how many times these go into 234ten ∙ 125 goes into 234 once, leaving
109; there are four 25s in 109, leaving 9; and, finally, the 9 can be written as one 5 and four 1s, so
our number is 12145.

42. (9 × 10) + (5 × 1) + (8 × 100) = 90 + 5 + 800 = 895; the correct answer is b.
43. (12 × 10) + 30,605 = 120 + 30,605 = 30,725; the correct answer is b.
44. (6 × 100,000) + (23 × 100) = 600,000 + 2300 = 602,300; the correct answer is c.
45. The digit being replaced is in the tens place. So, if the digit 1 is replaced by the digit 5, the number is
increased by (5 × 10) – (1 × 10) = 50 – 10 = 40. The correct answers is b.

13. They both have the value of 3 flats, 2 longs, and 1 single. Because base 6 flats and longs have greater
value than base 5 flats and longs, the two numbers do not have the same value.
14. Because we are dealing with powers. Thus, the value of a base 10 flat is 22 4 times the value of a
base 5 flat.
