A ready-made Autograph file to dynamically demonstrate how the gradients of perpendicular lines alter as the graphs move. Students can note down on the attached accompanying worksheet different pairs of gradients found, then find that the product is always -1. They can finish off by researching the relationship between the gradients - that they are negative reciprocals of each other. This mini investigation sheet can then be stuck into exercise books / notes to summarise the key points of this topic.
A sheet that helps pupils to discover the relationship between the gradients of perpendicular lines and then apply this relationship to solve problems.<br />
The two word versions require you to draw on the lines.<br />
Resource created by me, feel free to adapt and reshare.<br /><br />Perpendicular Gradient: This worksheet is differentiated by colour, encouraging students to use a formula to calculate the perpendicular gradient. Could be easily adapted.<br />
A self-contained game to be played in pairs.<br />
Use to revise reading coordinates on a grid. Best played once coordinates have already been introduced, as a consolidating activity.<br />
Differentiated versions of the game within this pack, including use of the first quadrant only, as well as all four quadrants. You will also find instructions on how to play the game within your pack. Suitable for Years 4 and 5 (on one quadrant) and Year 6 and KS3 (on all four quadrants).<br />
You will find a PDF version and editable Word version available for download; both are exactly the same, so download whichever is more convenient for you.
There are 4 sets of questions (Number, Algebra, Shape, Data) which are mainly A and A* (with some lower grade questions from topics which students struggle with, e.g. percentages, constructions). PLEASE REVIEW / COMMENT. Students work in pairs or small groups to answer the questions. When they finish a question they get it marked and if it is correct they are given cash to the value of the question. There are bank notes which you can put your school name and pictures of your teachers on. The team with the most money at the end could be given a prize.
