A selection of problems around interior angles for students to solve. Follows on from the investigation into how side lengths link to angle sums. Leads into exterior angles and other problems. EDIT: The first 4 slides for part of an Always, sometimes, never questioning session that I haven't obviously highlighted. I am fully aware that trapezium's don't have right angles. The task is designed to illicit misconceptions! Apologies for forgetting to signpost!

Relay for volume and surface area. Students apply the formulae provided on the exam paper to the full range of 3D shapes. They also have an opportunity to consider surface area.

These hexagons promote the discussion over length, area and volume for B to A* candidates. The idea comes from a English observation mentioned on the website linked and has been put into a mathematical context. Place like dominos explaining the decision for the tiles placement in its given location thus revealing the deeper understanding of the student.

Students run a school canteen. 1. They select 2 recipes to produce in their canteen. 2. They survey the class for demand for each dish using a tally chart. 3. They calculate the quantities required for each it recipe item in grams. 4. They round and convert into whole kg units to then cst each item. 5. They calculate profit by calculating total revenue and total cost. This activity worked well just before Easter as a competitive challeneg completed in pairs with a middle attaining year 7 group.

In this word document worksheet find the two mistakes hidden in 3 questions regarding angles around a point, a line and a triangle.

A quick and simply way to implement Isabella Wallace and Leah Kirman's idea of landing and boarding passes from their book Talk Less Teaching. The activity provide simple feedback to the teachers about prior knowledge, self assessment and where additional support is required.

Differentiated circumference questions.

From angles on a straight line through to isosceles triangles with a straight line. Answers at the bottom. They can be chopped of or used to self assess with a focus on correctly justifying your answer as opposed to simply correctly answering.

Another interpretation of 'Great Maths Ideas' work on knowledge organisers as a way of sharing learning intentions/objectives with students. Please leave a comment.

A thinking skills exercise. Placing different hat for different thinking types.

'I Think of A Number Cards' Designed to be 4 distinct sets of questions cards this resource is developed as an introduction to solving equations. It original design is to go alongside a lesson developing the idea of inverse to then be taken on to the solution of formal algebra. Set 1-Addition and Subtraction (1 Stage) Set 2 -Multiplication and Division (1 Stage) Set 3 - Multiplication then Addition/Subtraction (2 Stage) Set 4 - All 4 in any order (2 Stage) Second version doesn't provide answers.

Two differentiated worksheets on finding the missing lengths of similar shapes. Both worksheets conclude with a challenge question taken from GCSE exam papers.

A worksheet with problems on angles at a point, on a line and in a triangle. Differentiated worksheets designed for a middle year 7 group.
