This is a set of mixed questions involving angles in a triangle, Pythagoras' theorem, trigonometry, cosine and sine rules, similar triangles, area of a triangle. PLEASE REVIEW / COMMENT. I use it with students who are struggling to work out which bit of maths to use for different questions.
Practical uses of sine rule and cosine rule - triangulation and GPS. PLEASE REVIEW / COMMENT. Also see Uses of constructions & loci - triangulation é GPS.
Some examples of real statistics to add interest and variety to the topic. PLEASE REVIEW / COMMENT. Examples on normal distribution, equation of a line of best fit, Spearman's rank correlation coefficient, and choropleth maps. Other ideas or examples welcome, please feel free to contact me to add them in. NB: Notebook file was created on version 10 and does not display properly on the new version 11.
Featured in the TES Newsletter. Adventure game in which students answer probability questions in order to rescue a princess. PLEASE REVIEW / COMMENT. There are 5 sections, each with 2 topics. They have 4 attempts at each topic, if they get all 4 wrong, the game ends and they will have to start again. The 5 sections are: OR and AND questions, complementary events, combined events (inc. 'exactly' questions and 'at least' questions), conditional probability. Go to my profile page and check out my other games.
Some teaching and learning posters I have at the front of my classroom.
A poem I have written which I use to introduce BIDMAS to help learners to avoid the common misconceptions of thinking that D is done before M and A is done before S. PLEASE REVIEW / COMMENT
Questions involving different colours and numbers (and different sizes thrown in for good luck) to use both sides of the brain at the same time. PLEASE REVIEW / COMMENT. Notebook file is displayed on SmartBoard. Students use mini-whiteboards. Uncover the first question, students work out the answer and hold up mini-whiteboards, uncover the answer and then repeat with next question. Topics included: arithmetic, factors, multiples, mean and median.
Series of mental arithmetic questions which follow on from the previous answer. PLEASE REVIEW / COMMENT. Notebook file is displayed on SmartBoard. Students use mini-whiteboards. Practice questions are given on the left in green. Once ready, uncover each question in turn. When the final instruction is uncovered, students hold up their mini-whiteboards to show their answers. Uncover the bottom answer to check. Each page is progressively more difficult.
Lots and lots of activities and investigations based around number sequences. PLEASE REVIEW / COMMENT. They are not fully worked lesson plans, but rather some ideas for activities.
Gives a brief history of the calendar and the introduction of leap years and looks at some maths related to this. PLEASE REVIEW / COMMENT. NB: Notebook file was created on version 10 and does not display properly on the new version 11.
Two activities looking at symmetry of numbers. PLEASE REVIEW / COMMENT. Palindromic numbers is a short activity which can be used as a starter or time-filler. Turnnumbers is a longer investigation into patterns in numbers.
Cross curricular activity in which learners read a story about a conveyor belt made like a Möbius strip and investigate the properties of the Möbius strip. PLEASE REVIEW / COMMENT.
Three similar activities which involve colouring in all the square numbers, cube numbers, and prime numbers in grids to demonstrate that all squares are of the form 4n or 4n+1, all cubes are of the form 9n, 9n-1, or 9n+1, and all primes (except 2 and 3) are of the form 6n-1 or 6n+1. PLEASE REVIEW / COMMENT.
Activity involving square numbers and factors. Guards lock / unlock numbered cells following a set of instructions. At the end the cells which are left open are those with a square number because they are the only numbers with an odd number of factors. PLEASE REVIEW / COMMENT.
