## Scaling Our School

• Units of Work
• Number and Algebra
• Level Four

In this unit we look at estimating the length and height of buildings at your school. We then compare these estimates with the actual heights or lengths. Students will then build scale models selecting appropriate scales using ratio to translate the "real" dimensions into the dimensions for the scale model.

• Units of Work
• Geometry and Measurement
• Level One

In this unit we compare the weight of the students’ favourite soft toys directly and then indirectly using beads. Although the technically correct term to use is mass rather than weight we believe that at Level One it is confusing to be "particular" about the difference. As the students will be most familiar with the term weight we believe it is reasonable to use it to describe this week's activities.

## Tennis Ball Tubes

• Problem Solving Activities
• Geometry and Measurement
• Level Five

Use the formula for the circumference and diameter of a sphere to solve a problem

Devise and use problem solving strategies to explore situations mathematically (be systematic, make a model)

## Giant Mystery

• Units of Work
• Statistics
• Level Three

We have the hand print of a Giant…That’s all!! Can we find out how big this giant visitor was? By measuring other people, can we determine the relationship between hand size and body size, to help reconstruct the giant? The unit explores relationships between the hand length, width, span of a person and their height and other body measurements.

## Make a Measurement Maths Trail

• Units of Work
• Geometry and Measurement
• Level Two

In this unit students first go round a maths trail devised by the teacher. They then work in groups to devise and complete a maths trail of their own.  They then go round this new maths trail or, if another class can work in parallel, each class goes round the other’s trail.

## Taller/Wider/longer

• Units of Work
• Geometry and Measurement
• Level One

This unit encourages students to use measurement language and counting to compare the attributes of length, width or height of objects in a variety of game situations. The transition from counting all to advanced counting is also supported.

## Teddy Bears and Friends

• Units of Work
• Geometry and Measurement
• Level One

In this unit we compare the lengths of the students’ favourite soft toys directly and then indirectly using multi-link cubes.

• Units of Work
• Geometry and Measurement
• Level One

In this unit students use the traditional tale of the gingerbread man as a context for ordering and comparing lengths. A “Sessions” approach is used, with five related but not sequential activities.

## Time Capsule

• Units of Work
• Geometry and Measurement
• Level One

In this unit we take measurements of ourselves which we store in a time capsule to open and use later in the year.

## Dizzy Heights

• Units of Work
• Geometry and Measurement
• Level Five

In this unit we look at various ways of measuring the height of an inaccessible object. The fundamental piece of mathematics used here is the ratio of corresponding sides of similar right angled triangles. The actual measurements needed relate to (i) an intermediately placed stick and (ii) the tangent of an angle.
