Working scientifically


Human and physical geography

Pupils should be taught to describe and understand key aspects of:

  • human geography, including: types of settlement and land use, economic activity including trade links, and the distribution of natural resources including energy, food, minerals and water



Number, money and measure

Number and number processes

  • I can use addition, subtraction, multiplication and division when solving problems, making best use of the mental strategies and written skills I have developed. (MNU 1-03a)
  • Having determined which calculations are needed, I can solve problems involving whole numbers using a range of methods, sharing my approaches and solutions with others. (MNU 2-03a)


  • I can use the common units of measure, convert between related units of the metric system and carry out calculations when solving problems. (MNU 2-11b)


Planet Earth

Energy sources and sustainability

  • I am aware of different types of energy around me and can show their importance to everyday life and my survival. (SCN 1-04a)
  • By considering examples where energy is conserved, I can identify the energy source, how it is transferred and ways of reducing wasted energy. (SCN 2-04a)

Social Studies

People, place and environment

  • I can discuss the environmental impact of human activity and suggest ways in which we can live in a more environmentally-responsible way. (SOC 2-08a)


Mathematics: Skills

Solve mathematical problems

Pupils should be given opportunities to:

  • select and use the appropriate mathematics, materials, units of measure and resources to solve problems in a variety of contexts
  • identify, obtain and process information needed to carry out the work
  • estimate solutions to calculations; use alternative strategies to check the accuracy of answers

Mathematics: Range


Pupils should be given opportunities to:

  • use a variety of mental methods of computation; extend informal written methods to non calculator methods
  • round answers to calculations to an appropriate degree of accuracy

Handling data

Pupils should be given opportunities to:

collect data for a variety of defined purposes, including those that arise from their own questions, and from a variety of sources

Science: Skills


Pupils should be given opportunities to carry out different types of enquiry by:


  • where and how to find relevant information and ideas


  • form considered opinions and make informed decisions


  • describing how their have learned and identifying the ways that worked best
  • linking the learning to similar situations, within and outside school

Science: Range

The Sustainable Earth

Pupils should be given opportunities to study the properties of materials relating to their uses.

How things work

Pupils should be given opportunities to study the uses of electricity and its control in simple circuits.

Geography: Skills

Understanding places, environments and processes

Pupils should be given opportunities to describe the causes and consequences of how places and environments change, e.g. by season; from past to
present; the need for sustainability.


Pupils should be given opportunities to express their own opinions and be aware that people have different points of view about places,
environments and geographical issues.

Geography: Range

Pupils should be given opportunities to study living in my world: caring for places and environments and the importance of being a global citizen.

Pupils should be given opportunities to ask and answer the questions:

  • How have people affected this place/ environment?
  • How can I and other people look after this environment?

Mathematics and Numeracy


Operations and their Applications

Pupils should be enabled to:

  • develop strategies to add and subtract mentally
  • know the multiplication facts up to 10
  • engage in a range of activities to develop understanding of the four operations of a number
  • appreciate the use of brackets
  • add and subtract with up to two decimal places
  • multiply and divide decimals by whole numbers
  • use the operations to solve problems

The World Around Us


Pupils should be enabled to explore:

  • the effect of people on the natural and built environment over time


Pupils should be enabled to explore:

  • positive and negative effects of natural and human events upon place over time

Movement and Energy

Pupils should be enabled to explore:

  • the causes and effect of energy, forces and movement
  • causes that affect the movement of people and animals

Change over Time

Pupils should be enabled to explore:

  • the effects of positive and negative changes globally and how we contribute to some of these changes.
