KS2 Data

Data: use search technologies effectively, appreciate how results are selected and ranked, and be discerning in evaluating digital content. Understand computer networks, including the internet; how they can provide multiple services, such as the World Wide Web, and the opportunities they offer for communication and collaboration.

Databases Unplugged

This series of activities is aimed at upper-primary school students and above, and is intended as an introduction to organising and storing data. Kinaesthetic activities, paper-based and online tasks are used to support teaching of:

  • Branching databases
  • Fields and records
  • Searching including the use of wildcards
  • ​Structured queries including Boolean operators and Venn diagrams are used to aid understanding
  • Range searches using comparison operators
  • Sorting Key vocabulary is reinforced in each lesson.

The lessons progress from first principles of databases, moving to the use of online ‘cloud database’ tools, after the fundamentals have been firmly established.

Computer networks

A very comprehensive article from Quickstart Computing that explains how computers communicate, what the internet is and what services run on it. On the third page (labelled page 34) there is a very good unplugged classroom activity that can be used to model how packets of data are passed by the internet. The document also contains classroom activities that explore (amongst others) the following:

  • A role play relating to emails and their security.
  • Uniform Resource Locators (URLs) are the precise location on the Web where web pages or their components are stored. It’s what you type in to your browser’s address bar to request a page.
  • World Wide Web (WWW) usage across a week for different family members.
  • HyperText Mark-up Language (HTML) – which is the computer language in which the content and structure of web pages are described.
  • Search engines and how to filter searches.

Explaining data packets

An unplugged activity that simulates how data travels around the internet in packets. It involves cutting up pictures into ‘packets of data’ and then sending them to other students for them to reassemble the picture.

Network Hunt

Using the school network as a learning resource, this Barefoot Computing resource for primary schools introduces networked devices and the hardware infrastructure used to connect them.

Students carry out a ‘treasure hunt’, searching for common networked devices such as switches, servers and printers. After mapping these onto a sketch of the school, they are asked to match the devices to a description of their function.

Modelling the Internet Activity

Suitable for upper-primary teachers of computing, this Barefoot Computing activity focuses on the technical aspects of the internet explaining how it differs from the World Wide Web (WWW).

Students gain an understanding of the hardware that makes up computer networks and how IP addresses allow communication between computers. They consider the range of internet-connected devices, and how they use web browsers to display the pages of information stored on web servers.

Selecting Search Results

This Barefoot Computing primary school resource helps students to Understand how search engines work.

By acting as a ‘web crawler’ and collecting information across a small selection of web pages, they learn what in data is indexed by search engines and how this is used when a search query is received. As well as indexing using keyword counts, the students are asked to discuss ways to rank the results.

Binary bracelets

This resource introduces binary data to students via the creation of bracelets which display their name in binary. This lesson helps to demonstrate how it is possible to take something that we know and translate it into a series of ons and offs (ones or zeroes). The resource contains a lesson plan and related worksheets.
