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.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
This presentation was provided by Rebecca Benner, Ph.D., of the American Society of Anesthesiologists, for the second session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape." Session Two: 'Expanding Pathways to Publishing Careers,' was held June 13, 2024.
Leveraging Generative AI to Drive Nonprofit InnovationTechSoup
In this webinar, participants learned how to utilize Generative AI to streamline operations and elevate member engagement. Amazon Web Service experts provided a customer specific use cases and dived into low/no-code tools that are quick and easy to deploy through Amazon Web Service (AWS.)

6. SPIRAL
Adopts a spiral structure in the development
of concepts, skills & processes.
7. EXAMPLE: WHOLE NUMBERS
Grade 1- Numbers within 100
Grade 2- Numbers within 1 000
Grade 3- Numbers within 10 000
Grade 4- Numbers within 100 000
Grade 5- Numbers within 1 000 000
Grade 6- Algebra
SPIRAL CURRICULUM
The spiral opens up to revisit a concept taught in an earlier
year and to introduce related but more difficult concept.
8. SPIRAL CURRICULUM FROM GRADE 1 TO 2
Number Bonds
• prepare the children to learn their addition facts
• help in mental computations
Numbers to 100
• Interpret numbers within 100 in terms of tens
and ones
Addition and
Subtraction Within
1000 with renaming
• Prior knowledge
• Rote learning V.S conceptualised understanding
9. Activities and curriculum enable children to progress
from concrete and pictorial levels to abstract
representation.

learning.
CONCRETE PICTORIAL ABSTRACT
12. THE IMPORTANCE OF NUMBER BONDS
An important foundation for understanding how numbers
work. A whole thing is made up of parts. If you know the parts,
you can put them together (add) to find the whole. If you know the
whole and one of the parts, you take away the part you know
(subtract) to find the other part.
Number bonds let children see the inverse relationship
between addition and subtraction. Subtraction is not a totally
different thing from addition; they are mirror images. To subtract
means to figure out how much more you would have to add to get
the whole thing.
WHAT IS A NUMBER BOND?
A number bond is a mental picture of the relationship between a number
and the parts that combine to make it.
13. A) 1310 – 480 = ?
Compute the following subtraction equations.
B) 1000 – 480 = ?
Which equation is easier to compute? A or B? Why?
It is easier to take the place value of 10, 100 or 1000 to add or subtract.
By using 10, 100 or 1000 as a mean to add or subtract, it serves as a
effective tool of mental calculation.
A) 1310 – 480 = ?
1000 310
Working:
1) 1000 – 480 = 520
2) 520 + 310 = 830
14. 16 – 7 = ?

• Takes a longer time.
•Higher chance to make careless
mistakes.
• Fast
•Accurate
•Effective
•Prepares them for formal
