Key Stage 1 – Algorithms and Programming

The Aims

By the end of this session, you will:

• Explore some activities to teach Algorithms • Look at how to use Programmable Toys • Know what Apps could support KS1 • Become familiar with Scratch • Know about other programs which could help

support the Computing Curriculum at KS1

What do we need?

We need children to become digitally literate , to develop the knowledge, skills and understanding necessary to participate in todays modern society. This means we need to: • have access to a range of digital technologies • experience using devices in a variety of contexts • embed Information Technology into other subjects • give children access to a range of software, technologies

and online tools

Aims of Computing

The National Curriculum for Computing aims to ensure that all pupils:

• can understand and apply the fundamental principles and concepts of computer science, including abstraction, logic, algorithms and data representation

• can analyse problems in computational terms, and have repeated practical experience of writing computer programs in order to solve such problems

• can evaluate and apply information technology, including new or unfamiliar technologies, analytically to solve problems

• are responsible, competent, confident and creative users of information and communication technology.

Key Stage 1

Use technology purposefully to create, organise, store, manipulate and retrieve digital content

Information Technology

Key Stage 1

Understand what algorithms are; how they are implemented as programs on digital devices; and that programs execute by following precise and unambiguous instructions Create and debug simple programs Use logical reasoning to predict the behaviour of simple programs

Computer Science

Key Stage 1

Recognise common uses of information technology beyond school Use technology safely and respectfully, keeping personal information private; identify where to go for help and support when they have concerns about content or contact on the internet or other online technologies

Digital Literacy – E-Safety

Programmes of Study

3 Areas of Computing

Information Technology

Digital Literacy – E-Safety

Computer Science Over half of the curriculum now focuses on computer science:

• Computational Thinking - Algorithms • Programming and Controlling • Networks, The Internet

• Modelling, Creating & Designing • Photographs, Art, Animations • Data Handling

KS1 Computer Science

Computational Thinking

Algorithms

An algorithm is the step by step instructions needed to achieve a specific outcome. It is a sequence of commands

Everyday we use algorithms to complete tasks.

Getting Dressed Algorithm Brushing Teeth Algorithm

Making Tea Algorithm Making a jam sandwich Algorithm

Algorithms - Reception

• Display around the room pictures of everyday algorithms alongside the word 'Algorithm‘ to sequence.

• Use a kitchen role play area to make cups of tea, sandwiches for a teddy picnic (talk through separate steps)

• Blindfold a child robot for others to give instructions to walk through a maze

• Use Bee Bots and Mats

• Computer Programs - Children to explain 'what happens when' so they understand that the computer is following their instructions.

Vocabulary

Repetition

Statements that perform a repeat (or loops)

Forever, Repeat

Selection

Allows the program to make choices according to a condition:

if … then…..else

Sequence

All of the ‘steps’ that are followed in order

Debugging

Find and fix mistakes in a program

Variables

Something your program might need that changes score … speed ……time

Programming in Pairs

“… a software development technique in which two programmers work together at one workstation. One, the driver, types in code while the other, the navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently.

The Driver Types the code Thinks completing task using observer as a guide

The Navigator Thinks direction of outcomes Suggests improvements Looks for problems in the code
