In this video Paul Andersen shows you how to engage in argumentation in a mini-lesson on evaluating arguments. Two examples are included in the video and two additional examples are included in the linked thinking slides. <br/>

What happens when you divide things that aren't numbers?

Pupil outcome: I know that a regular polygon has sides that are the same length and angles that are the same size. Key learning points: - In a regular polygon, the sides are all the same length and the angles are all the same size - In...

Pupil outcome: You can identify and describe the relationship between two regular polygons using scale factors Key learning points: - Two similar shapes can be described as being 'x' times greater or smaller than each other. - If one...

Pupil outcome: I can find lines of symmetry in 2D shapes and explain the link between lines of symmetry and number of sides in regular polygons. Key learning points: - A line of symmetry splits the shape into two equal parts which are...

Pupil outcome: I can find the interior and exterior angles of regular polygons. Key learning points: - Exterior angles of a regular polygon are equal. - The size of the exterior angle of a regular polygon can be determined. - Interior...

This video explains lines of symmetry of 2D shapes including triangles, quadrilaterals and regular polygons. Practice questions and answers are at the end of the video.

This video provides a range of practice questions and answers on the topic of rotational symmetry.

Test your knowledge of interior and exterior angles in maths! This video provides a range of practice questions and answers on the topic!

This video explains interior and exterior angles of a polygon. In particular: how to calculate interior and exterior angle, how to find the sum of interior or exterior angles, and how to find the number of sides of a polygon with just an...

This video covers the names of polygons and 2D shape properties. Learn the difference between regular & irregular polygons and the names of these polygons such as pentagon and hexagon.

This video explains what tessellations are, and how to calculate if a shape will tessellate to form a pattern.

This video covers what we mean by 'regular polygons' and the different types you need to know. We also cover how many lines of symmetry and rotational symmetry they each have.



This video is suitable for maths courses...

Mr. Addit introduces tessellations. He talks about how tessellations are made, identifies tessellations, and names them.

Attributes of Shapes identifies shapes by reviewing their characteristics.

This video explores five fun facts about polygons.

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which...

In this video we are going to look at exterior angles of polygons. Exterior angles are a little strange. They make a straight line with the interior angle, rather than being the whole outside angle. There are a few different ways...

👉 Learn how to determine the number of sides of a regular polygon. A polygon is a plane shape bounded by a finite chain of straight lines. A regular polygon is a polygon whose sides are congruent (equal). The interior angle of a polygon...

👉 Learn how to find the volume and the surface area of a pyramid. A pyramid is a 3-dimensional object having a polygon as its base and triangular surfaces converging at a single point called its apex. A pyramid derives its name from the...

👉 Learn how to determine the measure of the interior angles of a regular polygon. A polygon is a plane shape bounded by a finite chain of straight lines. A regular polygon is a polygon whose sides are congruent (equal). The interior...
