Best Real-Life Math! RSA Encryption - All the math you need to encrypt data
By Daniel
Where do we use school mathematics in real life?
The following complete guide sets out ALL the mathematics we do in middle and early high school used in the RSA Public Key Cryptosystem.
RSA Encryption is one of the most modern and powerful methods of encryption and is used by computer scientists, big banks and websites who need to secure data.
Do not be surprised, the list is complete and no other, more complicated mathematics is ever used in RSA Encryption.
Topics done in grade school: Factors, Multiples, Products, Times Tables, Division, Remainders, Integers, Prime Numbers, Composite Numbers, Exponents, Rules for Divisibility etc.
Topics not specifically done in grade school but for which 7th-10th grade students possess ALL the mathematics knowledge: Modular Arithmetic, Successive Squaring, The Euclidean Algorithm, The Euler Phi Function, Euler's Formula, The Extended Euclidean Algorithm
It is important that students know (and that teachers always remind them) when they are busy with these topics, that they are learning fundamental mathematics needed to encrypt data and secret messages.
If you need the Tasks and Keys on All the Math needed for the RSA encryption, this is all of it, in A BUNDLE! Get it here:

The Sieve of Eratosthenes...you've been teaching it for years! Here's a new twist on the concept. Check out nicely the numbers fall into place when you use this format.
This PowerPoint includes:
-A ten slide presentation of the Sieve of Eratosthenese.
-Slide progression is already inserted into the PowerPoint. All you have to do is click!
-The last slide is a printable Student Handout that allows them to follow along with the presentation...definitions, Prime Numbers, and Composite Numbers.

Writing Linear Equations from Tables and Graphs - 6th Grade
By MsVisualizer
Students to write additive and multiplicative equations from tables and graphs at a 6th grade level with 9 pages (18 problems. Most of the problems are of the form y=kx or y=x+b with a few challenging questions at the end with 2 steps in the form y=mx+b.
This product contains 9 pages (18 problems)
The problems start easier and get progressively more difficult, including fractional slopes and y intercepts with decimals. Full Answer Key Included.
The google doc is pictures of each problem (consisting of a table, graph, fill in the blank description, and equation) so you can delete or add an entire problem but you can't edit each one individually.

Real-Life Math Fun practice/resource! Slope - A Student activity on Gradient.
By Daniel
It is always a good strategy to review essential skills with your students, and this is right up there with the most essential!
Slope (Gradient) is a very practical real-life experience for all of us - we climb stairs daily and walk up and down very steep and less steep inclines. In this practical, outside activity, students encounter slope first hand and then make sense of the mathematics behind it. Students are then encouraged to think about the real-life applications and implications that slope has in the life of people like the elderly and the handicapped.
Linear equations, slope, rise over run, gradient, y=mx+b.
