Bar modelling- a powerful visual approach for introducing number topics
Building on my recent post about a taxonomy for deep learning in maths, I have been trying to think a bit deeper myself about what each type of ‘deep learning link’ might look like. In particular, I have been researching and putting a lot of thought into what effective ‘visual models’ look like for the ‘key nodes’ I have previously identified as the most important foundation maths knowledge for students to master before starting their GCSE maths course. These are principally number topics. Last year I became aware of the Singapore Maths Bar Modelling approached have recently found the time to research it further. I bought some Singapore textbooks and read about the work of Dr Yeap Ban Har.

Radians to degrees
How to convert degrees to radians or radians to degrees. Theory: What are 'radians' ? One radian is the angle of an arc created by wrapping the radius of a circle around its circumference. In this diagram, the radius has been wrapped around the circumference to create an angle of 1 radian.
Quadratic Functions
How can you tell, by LOOKING at a quadratic function, if the vertex is going to be considered 'minimum' or 'maximum' and what exactly is the difference between the two vocabulary words? Well, if you stop and thought about the two words, you just might be able to come up with a logical conclusion. Since a parabola is a U-shape, let's take a look at what this shape looks like in a drawing again and see if you can come up with a conclusion all on your own. Okay, now think of the two words: minimum and maximum. What do they mean? Which of the two parabolas do you think just might indicate minimum and which just might indicate maximum?

Questions on Trigonometric Functions
1. Use the definitions of the six trigonometric functions and the Pythagorean Identity given in the Field Guide Lesson to show that: 1 + tan2(x) = sec2(x) 1 + cot2(x) = csc2(x)
Solving Trigonometric Equations
Solving Trigonometric Equations (page 1 of 2) Solving trig equations use both the reference angles you've memorized and a lot of the algebra you've learned. Be prepared to need to think! Solve sin(x) + 2 = 3 for 0° < x < 360° Just as with linear equations, I'll first isolate the variable-containing term:

Tricky crocodile maths question befuddles students - but can you answer it?
Earlier this year, a maths exam sat by students in Scotland was deemed so difficult that the pass mark had to be lowered. And now, a report has identified the chief culprit - a perplexing question about a crocodile stalking its prey. The pass mark for the new-look Higher maths exam - the Scottish equivalent of an A-level - was slashed to a lowly 34%. According to a report for the Scottish Qualifications Authority (SQA), the action was taken because of the overall difficulty of the test, as opposed to individual questions. However, the report, from the principal assessor in maths, does make specific reference to two questions which sparked outcry among students on social media.

Review : Trig Functions
The intent of this section is to remind you of some of the more important (from a Calculus standpoint…) topics from a trig class. One of the most important (but not the first) of these topics will be how to use the unit circle. We will actually leave the most important topic to the next section. First let’s start with the six trig functions and how they relate to each other.
