1 Unit Using Logo Year Group: 4 Number of Lessons: 4

2 Introduction The aim of the lessons is for the children to use Logo to follow and create simple algorithms. For the lessons, the children will need access to Logo on Purple Mash. If your pupils do not have individual logins for Purple Mash, we can help you with this. Contact your school Purple Mash administrator or us at To force links within this document to open in a new tab, right-click on the link and then select Open link in new tab. Year 4 - Medium-term Plan Lesson Aims Success Criteria To learn the language of Logo. To input simple instructions on Logo. For the children to use Logo to create letters. To use the Repeat function in Logo to create shapes. To use the Build feature in Logo. Children know what the different instructions are in Logo and how to type them. Children can follow simple Logo instructions to create shapes on paper. Children can follow simple instructions to create shapes in Logo. Children can create Logo instructions to draw letters of increasing complexity. Children can write Logo instructions for a word of four letters. Children can predict what shapes will be made from Logo instructions. Children can create shapes using the Repeat function. Children can find the most efficient way to draw shapes. Children can use the Build feature. Children can create flowers using Logo.

3 Lesson 1 Aims To learn the language of Logo. To input simple instructions on Logo. Success criteria Children know what the different instructions are in Logo and how to type them. Children can follow simple Logo instructions to create shapes on paper. Children can follow simple instructions to create shapes in Logo. Resources Lesson 1 Worksheet 1 and Worksheet 2 Pencils You may also want the children to use a protractor. Activities 1. Share the learning objectives and success criteria with the children. 2. Introduce the children to Logo. Explain that Logo is a way of writing simple algorithms which can then be displayed on screen. 3. Show the children Lesson 1 Worksheet 1. Alone or in pairs, look at the instructions and draw what shape the instructions will make. 4. Ask for children to read out their own instructions and see if the class can work together to draw these shapes. 5. Show the children the different instructions for Logo. A printable version of this is in Lesson 1 Worksheet At the computer, the children input the instructions from their worksheet. 7. EXTENSION 1 Input their own shapes. 8. EXTENSION 2 Can the children use the Pen Up and Pen Down instructions to draw all of the shapes on one screen?

4 Lesson 2 Aims For the children to use Logo to create letters. Success criteria Children can create Logo instructions to draw letters of increasing complexity. Children can write Logo instructions for a word of four letters. Resources Squared paper Lesson 2 Worksheet 1. Activities 1. Share the learning objectives and success criteria with the children. Then, recap the learning from the last lesson. 2. Show the children the letter E. 3. Explain that one square on the squared paper is the equivalent of one square in Logo. 4. Draw the letter E on the squared paper. 5. Explain they can use the Pen Up and Pen Down instructions. 6. With the class, draw the letter E in Logo. The instructions below are for guidance. You will need to change the numbers used to match the letter drawn on the squared paper. FD 10, RT 90, FD 5, RT 90, PU, FD 5, RT 90, PD, FD 5, LT 90, FD 5, LT 90, FD 5 7. The children log in to Logo and complete Lesson 2 Worksheet 1. They may need whiteboards or paper to draft their instructions. 8. EXTENSION Can the children write their initials in Logo?

5 Lesson 3 Aims To use the Repeat function in Logo to create shapes. Success criteria Children can predict what shapes will be made from Logo instructions. Children can create shapes using the Repeat function. Children can find the most efficient way to draw shapes. Resources Lesson 3 Worksheet 1 Squared paper. Activities 1. Share the learning objectives and success criteria with the children. Recap the learning from the last lesson. 2. Recap the work from Lesson 1 about how to draw a square. Show the children the instructions about how to draw a square FD 5, RT 90, FD 5, RT 90, FD 5, RT 90, FD 5, RT Look at the instructions. What do the children notice? (the same instruction is repeated four times.) 4. Introduce the Repeat function. This is written as REPEAT and then the number of times it is to be repeated. The instruction to be repeated is then placed in square brackets. So, to draw a square, the instructions can be shortened to REPEAT 4 [FD 5, RT 90]. 5. Hand out Lesson 3 Worksheet 1. What shapes do the instructions make? Can the children predict what shape will be made and then test it out to see if they were correct? 6. EXTENSION Can the children use the Repeat function to find the most efficient way to write letters?

6 Lesson 4 Aims To use the Build feature in Logo. Success criteria Children can use the Build feature. Children can create flowers using Logo. Resources Logo Lesson 4 Worksheet 1. Activities 1. Share the learning objectives and success criteria with the children. Recap the learning from the last lesson. 2. Explain to the children we want to draw four squares on the screen. Recap the learning from the last lesson about using the Repeat function. 3. Draw a square on the screen. Introduce the Pen Up and Pen Down rules. Draw two squares on the screen in different parts. Sample instructions could be: REPEAT 4 [FD 5, RT 90] LT 90 PU FD 4 PD REPEAT 4 [FD 5, RT 90]. 4. If I want to draw four squares, how long will this take me? 5. Introduce the Build instruction. This allows us to define a shape and write instructions.

For this activity, the children will use all that they have learnt to create some flowers.

7 6. To build a square, we would do the following: Type BUILD SQUARE Then, to draw a square in Logo, we just type SQUARE. 7. Ask the children to go to the computers and define some shapes, e.g. rectangle, triangle etc. 8. For this activity, the children will use all that they have learnt to create some flowers. This could be done by using the Build feature or typing in repeating instructions, e.g. BUILD SQUARE REPEAT 50 [SQUARE] REPEAT 100 [FD 3, RT 90, FD 3, RT 90, FD 3, RT 90, FD 3, RT 90, RT 5] 9. For further examples, please see Lesson 4 Worksheet 1.
