How to write a trigonometric ratio as a simplified fractions

Mantras from the early Vedic period before BCE invoke powers of ten from a hundred all the way up to a trillion, and provide evidence of the use of arithmetic operations such as addition, subtraction, multiplication, fractions, squares, cubes and roots. A 4th Century CE Sanskrit text reports Buddha enumerating numbers up toas well as describing six more numbering systems over and above these, leading to a number equivalent to Given that there are an estimated atoms in the whole universe, this is as close to infinity as any in the ancient world came.

They can be downloaded for free by registering on the TES website. Often pupils are very quick to tell me that they find algebra difficult before even giving it a try, but when introduced to it in the right way they are amazed that it was actually far easier than they thought.

This collection of resources is designed to provide an introduction to algebra topics, making them accessible to all; however, I have tried to include as many adaptable resources as possible so that they can be easily adapted to provide more challenge. Simple algebraic substitution Age range: Powerpoint Every time I use this resource someone in my department will ask me to send it to them.

Quick multiple choice quiz on the basic rules of algebra, which is then followed by a code cracker activity using basic substitution.

Maths Vegas Intro to equations Age range: Pupils work in teams writing their answers on mini-whiteboards and risking a certain number of points or poker chips if you prefer… per question based on how confident they are that their answer is correct.

An engaging resource that can be used at any stage of a lesson. Solving equations Top Trumps Age range: Word file My classes love using Top Trumps in their lessons and these are particularly eye catching as they have comic book characters on them.

Differentiated into red, amber and green sets, but all using level questions so even the most challenging is not too daunting for weaker groups.

How to Simplify a Ratio A : B A History of Mathematics.

Unlike many other Top Trumps I have found online, this resource is a word file so it can easily be used as a template to make your own set of Top Trumps cards.

Word file Some pupils find it easier to grasp algebra using symbols first and then progressing to letters. This worksheet provides that vital confidence boosting practise that some of them need to convince them they can do algebra after all.

For the first part of the worksheet pupils must work out the value of the symbol used and a final page gives potential for substitution practice. Simplifying expressions by collecting like terms Age range: PPT This excel file randomly generates expressions to be simplified.

The great thing about this resource is that you can change the maximum number of terms, different letters used, coefficients and whether or not it uses negatives; all of which means that you can ramp up the difficulty at whatever pace suits you. It provides a recap of several algebra topics.

I would recommend putting each sheet up as a poster and getting pupils to work in small groups to solve the problems around the room. Race track game Age range: Word file A race track game for pupils to play in pairs using dice and counters.

It uses number operations but also includes a blank version of the track where pupils can write the instructions as algebraic expressions.

Another option would be to get pupils to write in their own expressions on a track for another pair to play the game on. Function machine robots Age range: Pupils must decide on inputs and functions to write on different parts of the robot.

Their robot could be given to a partner to find the outputs giving an opportunity for peer assessment, and encouraging pupils to use more challenging functions. Co-ordinate mini murder mystery KS3 Age range: Word Another murder mystery activity, but this time a mini murder mystery on co-ordinates.Learn why the Common Core is important for your child.

What parents should know; Myths vs. facts. Empedocles of Acragas (c. BC) Inventor of rhetoric and borderline charlatan. His arbitrary explanation of reality with 4 elements (Earth, Air, Fire and Water) and 2 forces (Love and Strife) dominated Western thought for over two millenia.

A positive attitude is an important aspect of the affective domain and has a profound effect on learning. Environments that create a sense of belonging, support risk taking and provide opportunities for success help students to develop and maintain positive attitudes and self-confidence.

Acute is from the Latin word acus for needle, with derivatives generalizing to anything pointed or sharp. The root persists in the words acid (sharp taste), acupuncture (to treat with needles) and acumen (mentally sharp). An acute angle then, is one which is sharp or pointed. Sarcasm aside, it is an interesting read.

While the standard way of calculating a sine – via a look-up table – works and works well, there's just something unsatisfying about it.
