Tessellation Lesson
ChristopheGutierrezChristopheGutierrez

Tessellation Lesson

(3)
This Interactive Whiteboard resource allows students to discuss where they see tessellation in real life, practise some tessellations with regular and irregular shapes (including Escher's Reptiles, and attempting pentagons - which won&'t work), and design their own simple tessellation pattern. It includes a possible plenary inviting students to attempt to re-create the tessellation of pentagons and hexagons (as on a football) in 2D, prompting discussion on why this won&';t work.
A Thousand Origami Cranes

A Thousand Origami Cranes

(2)
This is quite a sad assembly about the symbolism of the origami paper crane, telling the true story of Sadako Sasaki and how she suffered from the effects of the dropping of the atomic bomb on Hiroshima. \n\nWe had just been doing an origami interform competition in my school, so it was nice to be able to tell them about the why the origami crane came to symbolise peace.
Area of Compound Shapes

Area of Compound Shapes

(27)
This is an introduction to the area of rectlinear compound shapes by way of a story. A rough idea of the story is that the teacher has bought a lovely new apartment, but the interior decor is horrible, requiring new carpets and floors. The teacher needs to measure the area of each room (starting with rectangles) and buy the right amount of flooring. The task can be extended to two more levels of difficulty.

Forming and Solving Equations using perimeters

(1)
This is a notebook file and worksheet containing about 8 questions in which pupils must form equations based on the perimeter of the shape and solve them to find the unknown, or find the area of the shape.\n\nThis is particularly useful at students targeting C grades at foundation.

Simple Enlargement Starter

(5)
A quick worksheet on enlarging shapes by a scale factor. Useful as a starter for a class to reinforce understanding of integer scale factor before moving onto enlarging from a point.
Describing Enlargements (integer, fractional and negative)
ChristopheGutierrezChristopheGutierrez

Describing Enlargements (integer, fractional and negative)

(1)
A worksheet for students to practise describing enlargements. Students should find the scale factor and the centre of enlargement for each image (the object is the shaded trapezium. Most are integer SF, but there are a few fractional and a couple of negative SFs (I prefer not to tell the students about this before, but get them to try to work it out themselves). Created because there doesn't seem to be much out there for this topic.
GCSE Foundation - Sometimes Isosceles Triangles are upside down

GCSE Foundation - Sometimes Isosceles Triangles are upside down

(1)
I can't remember how many times I've come across angles questions involving alternate angles and isosceles triangles in which my students haven't recognised that the isosceles triangles may not be in the orientation they first assume it to be in. This is a very basic resource to use as a starter / short main activity to help with this misconception. Not very flashy, but I hope it's helpful for some.

Global Village Assembly

This is an assembly along the theme of 'if the whole world was condensed down to this room, what would we look like?' Some of the numbers are estimates, but shouldn't be too far off.

Bearings Lesson - Lost at Sea!

(0)
This is a lesson to introduce bearings through a story (notes for which are attached). \n\nIt requires a bit of pre-planning, especially if the maps are wanted on A3, in colour and laminated (which is desirable, really)\n\nThe final task is self-differentiating, or can be omitted for lower ability groups
Spreadsheet and Mail Merge Certificates

Spreadsheet and Mail Merge Certificates

(0)
At the end of every half term, I send this spreadsheet to all Heads of Department for them to nominate students in each year group who have worked particularly well and deserve recognition. The mail merge automatically creates personalised certificates with a different picture for each subject.\n\nInstructions are included in the word document.
