This week we continued with the Relationships Unit with Pythagoras. This can be found on the MyMaths website under Library – Shape – Pythagoras – Pythagoras Theorem. We used Pythagoras to find the distance between two coordinates followed by a mixed exercise on the topic. The class were given a homework on the Mymaths website (Pythagoras) with a deadline of Tuesday 12th November for completion.

 We then spent one lesson on using a scale factor (including a fractional scale factor) to enlarge or reduce a shape.

 Next we had a recap of the various angle facts learnt in primary, S1, S2 & S3 before deciding what work needed to be covered regarding angles parallel lines, symmetry, triangles & quadrilaterals. This is under Library – Shape – Angles – Angle Sums / Angle Reasoning & Angles in Parallel Lines.

We continued the topic Multiples, Factors & Primes / Powers & Roots with a look at what is a factor? This was followed with testing squares/square roots and cubes/cube roots which the class are expected to learn. We then went onto investigating & learning about prime numbers before expressing numbers as prime factors. The work for this topic can be found on the MyMaths website under Library – Number – Counting & Place Value – Multiples as well as Factors & Primes, and also Number – Powers & Roots – HCF and LCM and also Squares & Roots

This week we continued with the Relationships Unit on recapping all of the previous lessons dealing with Equations as a final reminder of what they would be expected to manage to solve.

We then went onto the topic of Changing the Subject which tests the ability to rearrange an equation by working backwards through the mnemonic BOMDAS. This can be found on the MyMaths website under Library – Algebra – Expressions & Formulae – Rearranging 1.

 Next we started revising a topic covered towards the end of S2 and also in S2 – Pythagoras. This can be found on the MyMaths website under Library – Shape – Pythagoras – Pythagoras Theorem.

 The class will sit the Unit Test on the Relationships Unit probably the week beginning the 2^nd December. The pupils should refer to the summary of the topics in each Unit of Mathematics – National 4 to ensure they are clear on what will be in the test.

The class sat the test based on the topics covered Integers, 2D & 3D shapes – Triangles & Quadrilaterals (including Angles and Areas), Fractions, Ratio & Proportion and Equations & Expressions.

 The class sat an Upper Test at Level 3 and anyone getting 75% or above was given the Level 4 Test whilst anyone getting a less than optimal result was also given an easier test. The results of the test were given along with a review of the answers to the tests.

 We then started the topic Multiples, Factors & Primes / Powers & Roots with a look at what is a multiple? This was followed by copying two tables dealing with squares/square roots and cubes/cube roots which the class are expected to learn as this will help not only with this topic but later topics on Scientific Notation and Pythagoras. The work for this topic can be found on the MyMaths website under Library – Number – Counting & Place Value – Multiples as well as Factors & Primes, and also Number – Powers & Roots – HCF and LCM and also Squares & Roots and Indices 1.
