Starter - Prior knowledge The first part of the lesson focus’s on the rule for a parallelogram and calculating its area. The second part of the lesson includes algebra to find missing lengths. The plenary is a typical GCSE question. Please leave me your thoughts and comments as I can make improvements. I have used activ-inspire flipchart for the lesson but managed to screen shot all the slides onto powerpoint. Enjoy.

I have started with simple calculations by making numbers the subject first and then progressing onto letters. There is a good 3 to 4 lessons here which I believe covers everything to do with rearranging (including factorising expressions). Please see the preview, this will show you what the slides will look like for the tasks the pupils will be doing. This is fully loaded with examples for you, tasks for the students and of course, answers for everything! Please note that this is an activ-inspire flipchart, you will require Promethean boards in your school to allow this to work. There are no worksheets because everything is on this flipchart, 50 slides!

Contains a starter, explanations, worksheets and answers. Questions get progressively harder.

Contains a starter, an activ inspire flipchart, explanations and worksheets with answers. This focuses on calculating the mean, mode and range from bar charts.

Contains a starter, active inspire flipchart, 3 x worksheets which are also differentiated by outcomes. Assessments at different points in the lesson and a plenary. I used this for both KS3 and KS4, very suitable for a lesson observation.

Constructive lesson observation, friendly explanations, worksheets and lesson plan. As the students work through the polygons finding the number of triangles, they will clearly be able to identify and spot the pattern for subtracting 2. Starter - Prior knowledge and keywords (word search) Main worksheet 1 - finding sides, triangles and angle sum Main worksheet 2a - Puzzle for matching 'written polygons' with triangles and angle sum (Get your form to cut them out for the last 3 minutes) Main worksheet 2b - Extension tasks - finding missing angles, finding regular interior angles, working backwards and expressions. ppt/activinspire - constructive solid lesson with learning outcomes, explanations and answers The lesson consists of 3 assessment opportunities (beginning, middle and end/plenary to measure progress from the start)

Student friendly worksheets Section A - 14 questions to get your students reading scales before attempting distance time graphs Section B - consists of 6 questions for interpreting distance time graphs. Suitable for both KS3 and KS4

Excellent worksheet for measuring bearings. Included is a PowerPoint and activInspire flipchart. Suitable for KS4. Contains a starter, explanations and all answers are included.

Section A - Worksheet 1 is all about reading scales found on typical graphs where the scale isn't increasing by 1. Here we have 14 questions with structure to help your students get this part right. Section B - Here are 6 questions for interpreting from a distance time graph. Before students start the question, they have to work out what each division is worth for both Distance and Time for the question (what it's increasing by each time). This is structure to help them access the common distance time graph questions found on exams. For each question are a set of good quality questions. Powerpoint with starter and all answers to both worksheets. Very suitable for higher ability classes.

Differentiated worksheet First page - Plotting equations (positive), i.e y = 3x + 2 Second page - Plotting equations (negatives), i.e y = -2x + 1 Third page - Plotting equations (fractions), i.e. y = -1/2x + 3 I have also attached some past GCSE questions

Using a square (a), semi circle (b) and rectangle (c), these shapes are placed together or taken away from each other, the students are to give expressions for these. This is a good visual way for creating expressions and students find this engaging. This will help build up confidence. The worksheet offers good structure and understanding for adding and subtracting terms. I have also included some extra resources which progress nicely. This is suitable for all learners.

Here is a constructive lesson on constructing angles (60 degrees, 45 degrees, 30 degrees, 15 degrees) and perpendicular bisectors (of a line, at a point on a line, from a point to a line). For the second part of the lesson, I created videos for the students to watch which demonstrates the constructions (It can be a lot to listen too and this works well). I have taught this several times and once during an observation and it was a good solid lesson. Here you have to chance to assess learning outcomes with an assessment sheet and its fully differentiated. The worksheet is structured with steps and gives students questions to attempt.

Teaching direct proportion can be confusing for students. I have carefully thought about the introduction to this and have broken it down into manageable chunks. The lesson leads up to the complex questions (i.e. x is directly proportional to y). The new GCSE (1-9) requires students to draw the proportions on graphs and use them. I have added 6 questions on this. Answers and solutions are available for all work set. Includes detailed step by step explanations, my students really benefited from this. PowerPoint presentation and ActivInspire flipchart available.

These worksheets will give your students good practice for drawing box plots from given data.

I was fed up of just telling my students to multiply across, add this column, add that column, divide this column by the total of that one and there is the mean... This is what I ended up making: Starter - Students are asked to calculate the mean from a set of numbers (10 people who were asked how many pets they owned). Easy numbers to divide, straight forward. At this point, I like to demonstrate exactly what mean is How many pets do these people have? "Instead of saying this person has 2 pets, this person has 3 pets, this person has 1 pet etc... we just want one number, an average number called the mean which we just worked out" Main - The starter links straight into the main where the data is sorted into a frequency table and it's demonstrated how we get the same answer working from this table. I really break up the process and go through the whole "add them up" highlighting each of the same numbers and showing that we multiply across, students clearly see where things come from (see my cover image). On top of this, I have included 5 questions where students sort data into the frequency tables and find the mean (very structured and you can explain why they are multiplying across, adding and dividing). I have a section for just finding the mean from numbers in case some students need to work on finding mean from numbers. I also have a section for calculating mean from a plain frequency tables when your students really get the idea (so there is differentiation). I did this lesson with a weak year 8 class and they got a lot out of it. I highly recommend this, you won't be disappointed. One of my best resources. Answers are all included. Attached is an activInspire flipchart and worksheets.

10 questions to keep your students busy. Students are to sort data into frequency tables, then draw a bar chart from the table. They are then to use the bar chart to find the mode and the range. These worksheets progress from ungrouped data to grouped data. The tables use tally charts to keep track of sorting. Excellent resource to use with any class.

A very student friendly resource solving simultaneous equations graphically (8 questions). I made this because I was struggling to find any resource that just allow the students to practice the skill without having to get them to draw a graph or having the issue with the equations not crossing. I taught this by setting x = 0 and finding the y value. The equations are nice to work with when set to zero. This resource will save you a lot of time and effort.

Friendly and constructive worksheets Lesson 1 - Starter plotting co-ordinates. Main - Plotting quadratics GIVEN x and y values from a table, this gets students use to just recognising the shapes of quadratics. ActivInspire flipchart included with explanations and answers. Lesson 2 - Plotting quadratics where students need to find the y values given the x values from a table. ActivInspire flipchart included with explanations and answers. Lesson 3 - Plotting quadratics by finding x values from a table and solving given y values. I focused on x^2 equations to help students access quadratics. These lessons will set you up nicely for quadratics in the form x^2 + bx + c

A constructive worksheet for calculating the surface area of a cylinder. This can be used as a handout that students do whilst your explaining the steps. What do you think? Please leave feedback.

Venn diagrams is new on the 1 - 9 GCSE spec this year and I have thought about a good solid constructive lesson that will win students understanding with this. Firstly, I have based each question around two visual events (i.e. even numbers and prime numbers). The idea here is that students say which numbers are which and then place them into the Venn diagram. Then they are asked to calculate one probability question from it, they will struggle with this but that's where you step in to make sense of them with the example ready at the board. See the cover image as an example, I have made up 8 questions, each with a different probability. The lesson is an ActivInspire flipchart, explanations and answers. Students can work from a friendly worksheet. I have put in a suitable starter (listing multiple, factors, primes, cube numbers etc). I have also included in this lesson blank diagrams with the probabilities they need to be able to shade (answers included).
