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.

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!

Here are 3 lessons on place value. The worksheets are differentiated and student friendly. They follow on from each other. I have taught this several times and students have responded well to it.

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).

Here is a very constructive differentiated student resource that contains visual representations for how we divide fractions. Suitable for KS3 and KS4 Starter - Prior knowledge for multiplying fractions and converting mixed fractions to top heavy Assessment opportunities to measure the progress at the start of the lesson to the end. ActivInspire slides demonstrating the visual representations, explanations and answers (fractional parts can be visually moved to show one fitting into another) Paired activity - they get the chance to work on questions that contain dividing fractions with pictures. It offers a great opportunity for coming up with their own rule, they come so close working in pairs but sharing with the class, they figure it out which is what you and your observer wants, not you telling them the rule. Differentiated worksheet task - Suitable for all learners. Contains mixed fractions division and written questions higher ability as well as basic questions for weaker students. The Plenary is used to measure the progress from the start of the lesson - mini white board. This activity is also done at the start to show your observer what the students have learnt from the lesson. A descriptive lesson plan explaining everything you need to do. I have used this several times and hasn't disappointed me.

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.

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.

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.

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)

A constructive worksheet that clearly demonstrates positive (Q1), negative (Q2) and no correlation (Q3). The questions also include interpreting after plotting. Suitable for KS3 and KS4 Starter - plotting co-ordinates flipchart - consists of worksheet solutions

Constructive lesson that is student friendly. Starter - This is asking the students to write down what whole numbered co-ordinates are passing through an equation of a line. Prior knowledge to help. Section A - Simple with no axes and just focuses on positive gradient to build students confidence Section B - progresses with axes but still focuses on positive gradient Section C - This section focuses on negative gradient with axes Section D - This is a mixture for positive and negative gradient with axes Section E - This section is about finding gradient when the scales change, students need to think more about what they are doing. ActivInspire flipchart consisting of examples, explanations and answers to all worksheet questions. Suitable for KS3 and KS4

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

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.
