Yes, adding or subtracting the same number from each entry in a magic square will preserve the magic property, where all rows, columns and diagonals sum to the same number. This is because adding or subtracting a constant to each term in a sum does not change the total. So the underlying structure and relationships that make the square "magic" are maintained regardless of what constant is added or subtracted from each entry.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Embracing GenAI - A Strategic ImperativePeter 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.

4. Q. How did you work that out?
We can get the answer using:
the number fact 3 + 4
and then applying place value x 10
We can use a similar method for subtraction
LOOK….
50 – 20
The number fact is 5 – 2
And the place value is x 10
5. Try these using the same method where
possible:
80 – 50
70 + 40
34 + 54
75 – 40
46 + 52
58 – 25
80+ 40
7. L.O.2
To be able to add or subtract the nearest
multiple of 10 ,100 or 1000 then adjust.
8. Round these numbers:
1. To the nearest 10
34 27 78 66 55
2. To the nearest 100
167 761 354 855 21
3. To the nearest 1000
2435 7328 4982 6525 7721
Write in your books how much we had to adjust
each number by.
9. We can use rounding as a strategy for
addition and subtraction.
93 – 69
Thus:
1. What multiple of 10 is nearest to 69?
2. What is 93 – 70?
3. Have we subtracted more or less than
69?
4. How should we adjust the answer to
make it correct?
10. Our sum is:
93 – 69 = ( 93 – 70 ) + 1
= 23 + 1
= 24
This can be shown on a number line.
+1 -70
23 24 93
11. Our sum is now:
93 – 69 = ( 93 – 70 ) + 1
= 23 + 1
= 24
This can be shown on a number line.
-70
+1
23 24 93
12. We are going to try this: 368 + 51.
368 + 51 = (368 + 50) + 1
= 418 + 1
= 419
Draw the number line in your books.
+50 +1
368 418 419
13. Try this:
286 – 97 = (286 – 100) + 3
= 186 + 3
= 189
We need a volunteer to draw the number line!
14. Try this:
5250 – 1998 = (5250 – 2000) + 2
= 3250 + 2
= 3252
We need a volunteer to draw the number line
15. Try this
458 + 199 = (458 + 200) – 1
= 658 – 1
= 657
We need a volunteer to draw the number line
16. Do these :
include the written sum and the number line.
All groups: + Spheres + Prisms
289 – 98 756 – 197 2348 – 1996
645 + 69 572 + 196 5932 + 2995
584 – 97 615 - 498 3688 - 1994
1267 + 88 1546 + 997 5482 + 1988
17. Look at these:
73 + 26 182 – 95
6003 – 5994 56 – 29
73 + 200 583 – 71
Q. For which of these would you use the rounding
and adjusting strategy?
Q . How would you tackle the other questions?
18. By the end of the lesson the children should
be able to:
For example, work out mentally that:
274 + 96 = 370
as 274 + 100 – 4 = 374 – 4
= 370
and 4005 – 1997 = 2008
as 4005 – 2000 + 3
20. L.O.1
To be able to recall addition and subtraction
facts for each number to 20 and extending to
multiples of 10.
21. Write the answer in your books to the following:
15 – 7 12 + 8 9+8 3+4
7+6 11 + 11 14 – 5
12 – 4 6 + 13 8–5 17 + 6
19 – 10
22. Q. What strategies can we use for quick recall?
We can :
1. double and subtract or add
e.g. 6 + 7 = 6 + 6 +1
2. round up or down and subtract or add the
difference
e.g. 8 + 12 = 8 + 10 + 2
3. Subtract even numbers by halving it and
subtracting it twice
e.g. 16 – 4 = 16 – 2 - 2
23. We can use the same strategies with
multiples of 10.
Do these in your book:
70 + 60 10 +20 140 – 50 190 – 100
Can you see the similarities?
24. Q. Did you see the similarities?
Q. What strategies did you use?
33. Q. How many pairs of numbers sum
to 10?
1 + 2 + 3 + 4 + 5 + 5+ 6 + 7 + 8 + 9
= 5 X 10
34. Look at this calculation:
4+4+3+5
Q. What multiplication is this
equivalent to?
35. To find the answer we must first do the
calculation using our addition strategies.
4 + 4 + 3 + 5 = 16
16 is the equivalent to 4 X 4
Q Who got this right?
36. Q. How can we represent the
following as a multiplication?
18 + 20 + 22
37. To find the answer we must first do the
calculation using our addition strategies.
18 + 20 + 22
When we look at the numbers we can see that
18 and 22 make 40 ; a multiple of 20
20 is also a multiple of 20
That means that there are 3 multiples of 20 so
60 is the equivalent to 20 X 3
38. Let’s look at this one
48 + 49 + 50 + 51 + 52
Q. What strategies could we use to find
the sum?
39. To find the total we can;
1. look for numbers that sum 100
48 +52
2. start with the largest number first
52 + 51 +
3. look for multiples
50
4. look for unit pairs of 10
51 + 49
40. Showing your method, do the following
in your books:
18 + 19 + 20 + 21 + 22
26 + 28 + 30 + 32 + 34
64 + 66 + 70 + 74 + 76
83 + 85 + 90 + 97 + 95
41. Q. What strategies did you use to find
the answers?
Q. Which strategy do you think is best
for this calculation?
18 + 19 + 20 + 21 + 22
42. Copy this into your books
20 2 49 23
86 17 64 50
60 38 21 7
40 16 62 42
43. In your books write down sets of
numbers from the table that you can
total using all the addition strategies
we have looked at today.
46. Look at this calculation
35 + 36
Q What strategy could you use to find the
sum?
Look at the numbers, they are near doubles of
each other.
47. To calculate the sum we simply have to double one of the
numbers and adjust the answer.
E.g. 35 + 36 = (35 x 2) +1
70 + 1 = 71
OR
35 + 36 = (36 x 2) -1
72 – 1 = 71
48. Try these using one or all of the near
doubling strategies:
41 + 42 =
85 + 82 =
53 + 50 =
11 + 15 =
49. Now work out these calculations
17 + 16 and 1.7 + 1.6
Q. How did you work them out?
50. To find the sum of 16 + 17 we double and
adjust the numbers.
16 x 2 = 32
32 + 1 = 33
If 16 is the same as 1.6 x 10
and 17 is the same as 1.7
Q. How can this help us work out
1.6 + 1.7?
51. The answer is simple.
If 16 +17 = 33
then 1.6 + 1.7 = 3.3
We have divided 33 by 10
OR
moved the decimal point one place to the left.
52. In your books work out the following
using the same method
12 + 13 1.2 + 1.3
25 + 24 2.5 +2.4
44 + 43 4.4 + 4.3
TiP : do the whole numbers first
