Place knowledge

Geographical skills and fieldwork

Pupils should be taught to:

  • use simple fieldwork and observational skills to study the geography of their school and its grounds and the key human and physical features of its surrounding environment



Pupils should be taught to:

  • interpret and construct simple pictograms, tally charts, block diagrams and tables 
  • ask and answer simple questions by counting the number of objects in each category and sorting the categories by quantity

 Pupils should be taught to:

• count, read and write numbers to 100 in numerals; count in multiples of twos, fives and tens

• read, write and interpret mathematical statements involving addition (+), subtraction (–) and equals (=) signs

• add and subtract one-digit and two-digit numbers to 20, including zero

• solve one-step problems that involve addition and subtraction, using missing number problems

• count in steps of 2, 3, and 5 from 0, and in tens from any number

• compare and order numbers from 0 up to 100; use <, > and = signs

• add and subtract numbers including: a two-digit number and ones; a two-digit number and tens; two two-digit numbers; adding three one-digit numbers

• recall and use multiplication and division facts for the 2, 5 and 10 multiplication tables

• recognise, find, name and write fractions , ,  and  of a length, shape, set of objects or quantity. 


 Social Studies

People, place & environment

I explore and appreciate the wonder of nature within different environments and have played a part in caring for the environment. (SOC 0-08a)

I can consider ways of looking after my school or community and can encourage others to care for their environment.
(SOC 1-08a)


Information handling

I can collect objects and ask questions to gather information, organising and displaying my findings in different ways. (MNU 0-20a)

I have explored a variety of ways in which data is presented and can ask and answer questions about the information it contains. (MNU 1-20a)


Pupils should be enabled to:

• use addition, subtraction, multiplication and division when solving problems, making best use of the mental strategies and written skills they have developed

• show an understanding of how a single item can be shared equally, and the notation and vocabulary associated with fractions

• find a fraction of an amount by applying their knowledge of division

• compare, describe and show number relationships, using the symbols for equals, not equal to, less than and greater than.

 Health and wellbeing

Mental, emotional, social and physical wellbeing Through contributing my views, time and talents, I play a part in bringing about positive change in my school and wider community. (HWB 0-13a / HWB 1-13a)


Technological developments in society

Within and beyond my place of learning, I can reduce, re-use and recycle resources I use, to help care for the environment.
(TCH 0-02a)

Throughout all my learning, I take appropriate action to ensure conservation of materials and resources, considering the impact  of my actions on the environment.
(TCH 1-02a)



1. Geographical Enquiry and Skills

When studying places, pupils should be given opportunities to:

2. Collect and record information

3. Communicate ideas, information and their opinions, e.g. in pictures, speaking, writing.


Number 4. Classifying, Representing and Interpreting Data

 Pupils should be taught to:

2. Collect, record and interpret data arising from an area of interest for identified purposes, using an increasing range of charts, diagrams, tables and graphs


 Mathematical Development

 Pupils are able to:

• read and write numbers to at least 100

• compare and order 2-digit numbers

• use mental recall of number facts to 10 to derive other facts, e.g derive 60 + 40 from knowing 6 + 4

• count in 2s, 10s and 5s to 100

• find halves and quarters in practical situations

• mentally add 10 or 20 to a given number up to 100

• mentally subtract 10 or 20 from a given number up to 100

• solve one- and two-step problems that involve addition and subtraction, multiplication and simple division including missing number problems

• understand and use the different mathematical terms for addition, subtraction, multiplication, division and equals, e.g. find the total, share, goes into

• understand and use mathematical symbols for addition, subtraction, multiplication, division and equals.



The World Around Us


Pupils should be enabled to explore:

interdependence of people and the environment

the effect of people on the natural environment over time

interdependence of people, plants, animals and place



Pupils should be enabled to explore:

positive and negative effects of people on places


Change over Time

Pupils should be enabled to explore:

positive change and how we have a responsibility to make an active contribution


Personal Development and Mutual Understanding - PDMU

Mutual understanding in the local and wider community

Teachers should enable pupils to develop knowledge, understanding and skills in:

developing themselves as members
of a community


Mathematics and Numeracy

Handling data

Collecting, Representing and Interpreting Data

Pupils should be enabled to:

collect data, record and present it using real objects, drawings, tables, mapping diagrams,simple graphs and ICT software

discuss and interpret the data

extract information from a range of charts, diagrams and tables


Pupils should be enabled to:

• count, read, write and order whole numbers, initially to 10, progressing to at least 1000

• recognise and use simple everyday fractions

• understand the operations of addition, subtraction, multiplication and division (without remainders) and use them to solve problems

• know addition and subtraction facts to 20

• develop strategies for adding and subtracting mentally up to the addition of two two-digit numbers within 100.
