The perfect activity for your students during the end of year transition program. In this creative and mathematical activity students will use their knowledge of basic polynomials to design and graph a holly leaf. By combining linear and quadratic functions students will shape the characteristic curves of a holly leaf’s edges and veins.

In Part Three of this activity series, students unravel cryptic clues that move the one step further on the mathematical bridge connecting the ancient world of Pythagoras with Fibonacci. Students progressively uncover the fascinating realm of continued and infinite fractions, connecting the rational and irrational worlds. Discover how simple ratios can evolve into infinite complexity.

The investigation deepens as students continue their quest to uncover the connections between the Pythagoras’s theorem, the Pythagorean Circle and infamous Fibonacci sequence that will appear centuries later. In this episode students discover irrational secrets, numbers that can’t be tamed or fully expressed. While the Babylonians provide a numerical entry point, the hauntingly elusive square roots threaten to expand the number system.

This activity is part 4 of the module "Code by Numbers" which can be downloaded as a complete booklet from the STEM section of the website. In this activity students explore the set of numbers that possess more factors than all their predecessors, Highly Composite Numbers. Students incorporate some of their previous programs and algorithms to build a program that automatically finds Highly Composite Numbers. These numbers are rich for investigation, and are still be explored to this day!

This activity is part of the module "Code by Numbers" which can be downloaded as a complete booklet from the STEM section of the website. In this activity students explore the Euler Totient function, it sounds complicated, it's not, just really neat! The function determines the quantity of numbers that are co-prime up to the selected number (n). Students write some relatively simple code, chunking previous code to simplify the algorithm. There are so many observable patterns when studying the Euler Totient function for a set of numbers. Finally, students see a short cut method to perform the calculation. It's absolutely brilliant.

This activity is part of the module "Code by Numbers" which can be downloaded as a complete booklet from the STEM section of the website. In this activity students use one of the oldest mathematical algorithms and turn it into a Python program. The algorithm efficiently determines the highest common factor of two numbers. Students see how prime factorisation can also be used.

This activity is part of the module "Code by Numbers" which can be downloaded as complete booklet from the STEM section of the website. In this activity students explore the prime factorisation of a number and the total factor count with a view to establishing a rule to determine the quantity of factors for any number, based on the prime factorisation. Students write a program to determine the quantity of factors.

Students use interactive content to investigate the six trigonometric functions: sine, cosine, tangent, secant, cosecant, cotangent, including relationships between each. The unit circle animation helps build the relationships, which they derive and prove. The second stage of the investigation has students building relationships for double angle formulas, thanks to a series of visual prompts. The Word document can be edited to suit your needs, so too the companion TI-Nspire file.

Turn your name into a Polynomial. Are there any two names that share the same polynomial? Students explore names and polynomials, including what happens to palindromic names, what degree is their polynomial? This investigation is provided as a Word document for teachers to edit and customise for their students. A PowerPoint slide show is ready to go, suggested answers and TI-nspire files, this investigation has it all wrapped up!
