A kaleidoscope is an optical instrument in which bits of glass, held loosely at the end of a rotating tube, are shown in continually changing symmetrical forms by reflection in two or more mirrors set at angles to each other.

A kaleidoscope operates on the principle of multiple reflection, where several...

A short, healthy outburst of anger will often solve problems. Unhealthy anger, by contrast, is damaging. Teachers are required to manage increasing numbers of students who struggle to control their anger and who court conflict. This pocketbook equips teachers with strategies for succeeding at that task.

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of angle, from identifying right angles to working with bearings.

Angle pack one contains eight work cards with a wide variety of activities covering...

Connect 4: this activity requires students to choose a diagram and use their knowledge of angle facts to find the size of the desired angle. Player one answers their question then finds, and shades in with one colour, the answer on the answer grid. Player two then takes their turn, shading their answer using a...

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of angle properties, from investigating the sum of the angles in a triangle to calculating the size of angles in a circle, and a separate booklet of geometric facts.

...

This investigation covers two circles theorems through one demonstration. The theorems are:

• That the angles on the same arc forming a chord are equal

• That the angle at the centre is twice the angle at the arc when drawn from the same chord

The initial...

This item is one of over 25,000 physical resources available from the Resources Collection. The Archive Collection covers over 50 years of curriculum development in the STEM subjects. The Contemporary Collection includes all the latest publications from UK educational publishers.

This resource consists of 22 instant maths ideas, ideal for use as starter questions, extension question or probing questions to assess understanding, requiring students to: * know the names of different kinds of angles * demonstrate the use of angles using physical activities * explore the angles associated with...

This resource contains a collection of dynamic and interactive spreadsheets designed to illustrate teaching points on the topic of angles.

The first sheet provides screens on the following:

This MEP resource from CIMT is taken from text book 7A which covers the mathematics scheme of work for the first half of year 7. This resouce covers; angles: a measure of turn, points of the compass, measuring angles, classifying angles, angles on a line, angles at a point, constructing triangles and finding angles...

This resource consists of two interactive excel programs. The first deals with basic angle facts and recognition of types of triangle. Depending on how it is used, the second could require the use of Pythagoras' Theorem and trigonometry. The second excel file could also be used to provides problems relating to the...
