The American War for Independence lasted from 1776 to 1783 and saw the colonies defeat Great Britain to gain independence. Key battles included the Continental Army's surprise attack on Hessian forces in Trenton on Christmas night 1776, which boosted morale, and the British surrender at Yorktown in 1781 after France entered the war. The Treaty of Paris in 1783 officially recognized the United States as an independent nation.

Examples are provided to demonstrate estimating the square roots of 27 and 15 by identifying the nearest perfect squares and interpolating between them.

Maths T5 W2
The document provides examples and practice problems for multiplying numbers by 10 and 100. It begins by explaining that to multiply by 10, each digit moves one place to the left, with zeros added as placeholders. To multiply by 100, each digit moves two places to the left. Several examples are worked out step-by-step. The document then provides practice problems for students to multiply one-digit, two-digit and decimal numbers by 10 and 100. It concludes by reminding students that multiplying by powers of 10 involves shifting the digits to the left by the corresponding number of places.
Power ranger exponents
This document provides examples and rules for evaluating expressions involving exponents. It explains that the power tells you how many times to multiply the base together. It also covers rules for adding, subtracting, multiplying and dividing exponents, as well as raising exponents, products, quotients and zeros to a power. All nonzero numbers raised to the power of zero equal 1, regardless of the base.
Chapter1.8
The document provides examples of solving simple linear equations by using properties of equality and the identity property of multiplication or division. It demonstrates solving equations involving multiplication or division by undoing the operation through dividing or multiplying both sides of the equation. Examples include solving equations like 6x=48 by dividing both sides by 6, or solving an equation like 25x=450 by dividing both sides by 25 to isolate the variable.
1150 day 10
This document covers topics related to repeating decimals, irrational numbers, and square roots. It includes examples of writing repeating decimals as fractions, ordering decimals, finding square roots, and using the Pythagorean theorem. Various math problems are presented along with step-by-step solutions to illustrate these concepts.
PEA 305.pdf
The document provides information on various number system concepts in Vedic maths including:

A Strategic Approach: GenAI in Education
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.
