A great introduction to understanding sorting and searching algorithms including bubble sort, insertion sort, merge sort, linear search and binary search. These ready to use sorting and searching algorithms lessons will save you hours of preparation and can easily be adapted to meet your own requirements.
WHAT IS INCLUDED?
In this unit you have 3 ready-to-use lessons:
Bubble sort
Insertion and merge sort
Linear and binary search
.
These lessons include everything you need such as:
a very high-quality accessible PowerPoint presentation for every lesson that effortlessly leads the teacher through the lesson and includes all the answers to the many questions and tasks the students need to complete
an editable worksheet for every lesson
an easy-to-follow editable lesson plan for every lesson
.
Not only have you got the complete lessons above but if you wanted to extend the unit I have made it extra easy by also including the Python programs (both with and without comments) for each of these algorithms. I have even created handouts for each algorithm written in pseudocode code using the specifics of OCR, AQA and Edexcel.
You could use these Python programs to show the code to the pupils and ask them how it works and talk through the code with them comparing it to the algorithm, you could challenge them to add comments themselves to explain the code or use it to demo a working program.
If you feel your pupils are able, you could set them the challenge of programming it themselves and use the completed programs as exemplar material to aid pupils who get stuck or even remove some of the code and ask them to complete key areas to make it work.
PRIOR LEARNING
This unit does expect pupils know what an algorithm is and be familiar with understanding written algorithms and flowcharts.
EASY TO USE
These ready to use resources are so straightforward that although I have included a lesson plan, most teachers can teach straight from the PowerPoint presentation without any further assistance. And best of all, the answers are included saving you time and energy.
This makes these lessons suitable for experienced computing specialist teachers along with non-specialists and early career teachers.
EDITABLE RESOURCES
I understand that teachers want to adapt their resources, so I’ve made the bold decision to make these resources editable.
Therefore, if you need to use a particular template style for your school or pupils with special educational needs, you can change the PowerPoint presentations, worksheets and lesson plans to suit your needs.
These lessons are highly interactive and engage students straight from the start.
Start reaping the benefits today of incredibly high-quality, professionally designed teaching resources that you can use with virtually no preparation.

HOW CAN I USE THESE FLASH CARDS IN MY CLASSROOM?
Your students pick a card and create the programming challenge described on the front of the flash card. Once they have created their Scratch program, students test their completed program and turn over to see the suggested Scratch code answer on the reverse of the card. If they get stuck, they can always turn the card over to see the suggested solution they can copy.
When they have their program working correctly, students swap their flash card for another and repeat the process.
Students can work individually or in pairs for this activity and love the competitive nature of using these flash cards as they see how many they can complete.
These flash cards are great when used as:
a starter,
a plenary,
