This lesson is suitable for lower and upper ability students. The work is differentiated and I have taught this to a mixed ability class. I have put bar model into the questions (its a fantastic method of teaching ratio). Suitable for both KS3 and KS4 The lesson focus's on the following skills and the worksheet is structured this way: First section - Sharing out amounts - boxes are used for visual representation (bar model) Section section - Given the ratio and the quantity, students are to find the other quantity (bar model) Third section - Students are to find the totals given the ratio and a quantity (bar model) Fourth section - This is a mixture of questions and students are to construct bar models There is assessment opportunities to measure the progress at the start and at the end of the lesson. The starter Is basic division which I find works very well to settle students down quickly at the start of a lesson. A lesson plan is attached explaining how I have gone about it.

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 very constructed first lesson on surds. I had a lesson observation and needed to teach surds, due to its nature, it can be difficult to think about differentiation, progress, teamwork and at the same time, keeping it constructive. I thought about all of this and the lesson was a success ensuring every student achieved something from my set learning outcomes. I recently taught it again for another lesson observation and it didn't disappoint me. Starter - Square roots and factors (prior knowledge) Pair activity - Identifying surds Main worksheet activity - Fully differentiated Lesson plan - I have put lots of thought and detail into this lesson. Assessment - Progress is checked at the start of the lesson and at the end (use mini whiteboards) ppt - activInspire. All answers to worksheet are included. This lesson will focus on rewriting surds, simplifying surds and progressing to add/subtract them.

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.

Everything you need for a lesson observation is here. This is a very constructive lesson that you will not be disappointed with. This is an active inspire flipchart with worksheets. Starter - Basic Scale Factor for enlargement of squares, rectangles and triangles with answers provided. Discussion 1 - The starter links for discussing what similarity is from the shapes they enlarged. Students are shown two shapes and are asked if they are similar and why. This being that the lengths have been multiplied by the same number (SF) meaning they are similar. Identifying similarity, congruency and none is discussed here. Activity 1 - Pair activity identifying similarity, congruency and none + answers Discussion 2 - Identifying Scale factor from two shapes given they are similar. Working out SF and finding missing lengths. Challenging similar triangle shapes included for discussion. Activity 2 - Differentiated worksheet task covering all of the above. - Calculating SF - Finding missing lengths using SF - Finding missing lengths for complex triangle similar shapes Answers included Plenary - Provides a link to the real world or to test them against the GCSE question at the start to demonstrate good progress

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.

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

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)

Interpreting line graphs can be a tricky skill for students when the scale isn't straight forward. I have firstly focused the lesson on reading scales and working out divisions (what it's increasing by). The second half is to apply this skill to interpret and access the sorts of questions they will come across. Both worksheets are student friendly and are aimed at KS3 and KS4 The flipchart contains a starter, explanations and worksheet answers. Please see my other lesson on plotting and interpreting line graphs.
