This is a resource for Grade 10 through 12 factoring in Saskatchewan! An easy to follow flow chart with a few examples.

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 Concrete, Pictorial, Abstract Approach is an effective teaching approach that helps to develop a deep and sustainable understanding of mathematics in students.

When integrated into your classroom it helps to build on your students existing understanding and making complex mathematical concepts accessible to all.

Concrete: refers to the 'doing' stage. Where students manipulate concrete materials to solve problems. This is the first stage of the approach or framework.

Pictorial: refers to the 'seeing' stage. Where students create visual presentations of the concrete objects that they have just used to model the problem. This allows students to make connections between the objects they have just used and the abstract pictures they have drawn.

Abstract: refers to the 'symbolic' stage. Where students use numbers and symbols to model a problem. This is the final stage to mastering a concept. Students will not move onto this stage if they do not have a solid understanding of the concrete and pictorial representations.

It is also important to go back and forth, continually practicing each stage to reinforce mathematical concepts.
