This interactive workbook begins with a sheet which illustrate properties of odd, even and consecutive numbers. These properties are illustrated numerically and algebraically. The next two sheets deal with properties of the sum, difference and product of these numbers...

In this STEM club activity, students design and build an earthquake-resistant two-storey structure, considering principles of earthquake engineering and design such as the importance of a solid foundation, wide base, symmetrical design and trusses.

This resource consists of two interactive excel files dealing with some aspects of construction and geometric proof.

Perpendicular Bisectors...

This resource provides a practical context to explore the uses of everyday materials, based on their properties. Children are introduced to a problem of building a flood- proof home, which is faced by families in local communities in Bangladesh, looking at solutions that have been developed to solve this problem....

This resource from Defence Dynamics asks students to create and interpret a variety of graphs. The types of graph covered are time series, moving average, stem and leaf, cumulative frequency and scattergraphs.

...

The objectives of this activity are to develop a chain of reasoning and to understand the application of mathematical induction to proving divisibility. Students are given a set of cards. The cards have to be arranged in such a manner that they form the solution to a problem together with justification for their...

Two Repeats covers the revision of algebraic topics including changing the subject of a formula, graphical solution of equations, solving simultaneous and quadratic equations and manipulating surds.

...

This RISP activity is ideal for introducing, consolidating or revising the idea of proof using a mathematical argument and appropriate use of logiocal deduction.

Students are asked to choose two triangular numbers and...

This task is designed to assess how well students understand geometrical proofs.

The task presents three attempts to prove Pythagoras’ theorem. Students must look carefully at each attempt and determine which is the best ‘proof’. They must explain their reasoning as fully as possible.

This task is...

This resource provides a cross-curricular design and technology and science project aimed at primary children. Using the context of the school class going to Greenland and forgetting all their shoes, children are asked to construct shoe soles that will insulate them as they take part in a dog-sled trip. Children...

This resource from Inquiry Maths is designed to stimulate exploration of the nature of simultaneous equations.

Simultaneous equations...

This Science upd8 resource examines what proof there is that mobile telephones are harmful. Policy makers usually follow the precautionary principle. They issue warnings at the first hint of danger. Should we take their advice? In this discussion activity, students judge the risks and the strength of the evidence...

In this resource, students consider whether two Poisson distributions can be added together to form a third Poisson distribution. The initial, discussion generating proposition is backed up by a proof. The resource also contains an accompanying spreadsheet on which students can run simulations to test the result....

The equations of two intersecting lines are given. The challenge is to use Pythagoras’ theorem to show that the triangle formed by the lines and the y-axis is a right-angle. The point of intersection is determined by solving simultaneous equations.

Each example is derived from a pair of perpendicular lines....

This resource consists of 23 instant maths ideas, ideal for use as starter questions, extension question or probing questions to assess understanding, asking students to: * investigate the area of tilted squares * explore whether Pythagoras’ theorem works for all triangles * find a proof for Pythagoras’ theorem *...
