Basic Index Laws: Games, Set, Match
This video demonstrates how to use index notation to establish index laws with positive integral indices and the zero index. Using the example of Grand Slam tennis tournaments, our narrator constructs his own school based tennis tournament draw...Show More
This video demonstrates how to use index notation to establish index laws with positive integral indices and the zero index. Using the example of Grand Slam tennis tournaments, our narrator constructs his own school based tennis tournament draw using index laws with two as the base number. Viewers also learn how to multiply and divide numbers in index form with the same base. Ideal for applying mathematical concepts to real world situations. Show Less
Basketballs, Parabolas and Circles
There's a lot of geometry on a basketball court! This video explores the connection between algebraic and graphical representations of relations such as simple quadratics, circles and exponentials through examples of lines on a basketball court,...Show More
There's a lot of geometry on a basketball court! This video explores the connection between algebraic and graphical representations of relations such as simple quadratics, circles and exponentials through examples of lines on a basketball court, and the trajectory of free throws. Ideal for reinforcing concepts. Show Less
Best Buys: Buying or Making Sandwiches
A group of friends are planning a lunch and compare the costs of pre-made lunches versus making it themselves. They investigate their options by comparing total costs and per person costs. Calculations are determined with and without digital...Show More
A group of friends are planning a lunch and compare the costs of pre-made lunches versus making it themselves. They investigate their options by comparing total costs and per person costs. Calculations are determined with and without digital technologies. Ideal for applying mathematical concepts to real world situations. Show Less
Calculating Profit: Earning Your Bread and Butter
Our presenter is interested in running her own café and decides to see what profit can be made from selling sandwiches. She works through the individual costs of sandwich ingredients to compare against café sandwich prices, then calculates her...Show More
Our presenter is interested in running her own café and decides to see what profit can be made from selling sandwiches. She works through the individual costs of sandwich ingredients to compare against café sandwich prices, then calculates her potential profit (percentage). She quickly learns there's more to her costs than just ingredients. Ideal for applying mathematical concepts to real world situations. Show Less
Destination Distances on a Cartesian Plane
When the Smithton River floods five local towns, a plane needs to drop supplies at each. A route needs to be determined that will reach the most affected areas first, while ensuring the plane has enough fuel between stops, and that the pilot...Show More
When the Smithton River floods five local towns, a plane needs to drop supplies at each. A route needs to be determined that will reach the most affected areas first, while ensuring the plane has enough fuel between stops, and that the pilot complies with regulations about consecutive flying hours.
Follow the relief operation as we use a Cartesian plane to determine the distances between each town and plan a successful operation. Strategies used include Pythagoras' Theorem and graphing software. This is an excellent resource for applying mathematical concepts to real world situations. Show Less
Graphing Distance and Time: A Runner's Story
This video follows a runner graphing his running distance and speed. He explains what happened along the route that affected his speed, translating this information onto a graph and accounting for the varying steepness of gradients between...Show More
This video follows a runner graphing his running distance and speed. He explains what happened along the route that affected his speed, translating this information onto a graph and accounting for the varying steepness of gradients between different points along his graphed journey. This is an excellent resource for applying mathematical concepts to real world situations. Show Less
Graphing Simple Parabolas and Circles
This video begins with a short introduction of everyday applications of circles and parabolas. Next, basic parabolas and circles are graphed using quadratic equations. Ideal for reinforcing concepts.
Index Notation and Prime Factors
This video provides a short lesson on index notation and representing whole numbers as products of powers of prime numbers. Examples of raising base numbers to different powers are shown. Prime and composite numbers are explained and factor trees...Show More
This video provides a short lesson on index notation and representing whole numbers as products of powers of prime numbers. Examples of raising base numbers to different powers are shown. Prime and composite numbers are explained and factor trees are used to express numbers as products of their prime factors, determine HCF (highest common factor) and LCM (lowest common multiple). Step by step graphics; ideal for reinforcing concepts. Show Less
Line Graphs: Gradients and Midpoints
This video follows a sprinter graphing her distance and speed for two separate sprints. The first sprint is at a constant speed, resulting in a straight line graph. In the second sprint, her graph reflects three distinct intervals as her speed...Show More
This video follows a sprinter graphing her distance and speed for two separate sprints. The first sprint is at a constant speed, resulting in a straight line graph. In the second sprint, her graph reflects three distinct intervals as her speed differs over the course. Follow along as she determines gradients and midpoints and her average speeds for both sprints as well as her speeds at different intervals. This is an excellent resource for applying mathematical concepts to real world situations. Show Less
Perfect Squares and Square Roots
