Year 4 Logo (Roamer World) Updated 09 November 2006
Learning Objective Lesson 1	Lesson Plan
· Learn how to program a set of simple instructions · Revise or introduce 90 degrees · Revise left, right, forward and back	· Find a large space with not too many distractions (Hall or playground) · Explain that you are going to test pupils’ ability to follow instructions. · Choose one child and demonstrate giving them instructions (one = step, right or left 90) o Start with one thing (forward 1, back one, right 90 or left 90) o Move on to two instructions · Now encourage all the pupils to find a space and start with one then two then a series of three instructions. · Now introduce go at the end. Pupils mustn’t move unless the go signal is given and they execute the instructions. · After a while make a game out of it and eliminate players who move before the go or get the instructions wrong. · If they are good at this give commands to separate groups such as girls, boys, trainers, jumpers etc. · Stop pupils and ask them if this series of movement reminds them of anything (many pupils may have used roamers in infants schools or logo toys such as programmable cars etc) · Explain that we have a program in school that allows us to give instructions similar to those we would have given to a roamer except the Roamer is on the screen. · Move onto the computers, load Roamer World · Demonstrate basic moves and how to reset the Roamer position. · Demonstrate clearing the screen by double clicking ce and clearing a line of code by clicking c · Let pupils experiment with a series of moves. · Save as logo1 · Explain that next week we are going to use the roamer to draw shapes.

· Simple logo series of instructions	If pupils don’t know their left from right either teach the thumbs out left & right or give pupils something to hold in their right hand.	When you move from physical to digital it makes more sense to pupils. Don’t be afraid to spend most of the lesson in the hall or playground adapting the physical aspects of this.	Large space hall or playground
Learning Objective Lesson 2	Lesson Plan
· Investigating Angles in 10 degree increments	· Stand at the front and ask pupils what angles we used last week (90° and 180°) Explain that we could count in small 1° increments until we have completed 360 of these and made one complete turn. Demonstrate this physically by moving round. · Or we could use larger segments like 10° at a time (go to 90° moving in 10° increments or get a pupil to do it) Do this both right and left so that pupils realise that we can count both ways. · Explain that we are going to investigate angles by doing a series or turns of the same amount followed by forward movement. · Load Roamer World and demonstrate how to change the roamer screen to 20 by 20 so they have more room to draw. · Move the roamer to the left hand side · Type in fd 1 rt 10 fd 1 rt 10 fd 1 rt 10 fd 1 rt 10 etc · Ask pupils what pattern/shape it makes · Now set them of to explore 20°, 30°, 40° etc · Some time in this activity stop the pupils briefly and show them how to save the Roamer command set. · Go round and ask them what shapes it makes? (In my experience pupils can get quite exited about this)
ICT Skills	Able & SEN Support	Notes	Resources
· Saving the command set for each set of commands	Able pupils who finish can record elsewhere what number of forward instructions and turns produce what shapes (Publisher table or excel spreadsheet) Able pupils can also move on to investigate increasing or decreasing angles in a series.	Pupils can discover angles and regular shapes themselves though this activity. Printing a selection of these for display or further maths work in this area can reinforce ideas across subjects.
Learning Objective Lesson 3	Lesson Plan
· Creating a human Roamer route · Following a human Roamer route. · Using a protractor sheet to measure an angle less than 90° in 10° segments	· Firstly explain how to use the protractor sheets to make turns · Play a simple game of directions where pupils must call out what direction change they are making using logo calls such as right 20 or left 45 etc · Demonstrate how to create a simple path with 90° turns. (50cm being one pace, if you include more than one pace mark it on the line. Mark the angles on the turns) Remember it is an angle from straight ahead not the angle between the two lines however if you use the protractor sheets this will be obvious · Now get the class to write a series of instructions in their notebooks to give to their human roamer robots to follow the line. · Pair up and try their instructions on a human roamer robot. · Now demonstrate how to create another route but introduce angles less than 90° (in 10° increments so it builds on last weeks activity) Mark on the angles what they are in degrees. · Again get pupils to write in their notebooks a human roamer robot route in their notebooks. · Get some pupils up to test their routes. · Now challenge pupils in pairs to create a route using the same 50cm distance for one step and 10° increments for turns. Get them to start simple with only 4 straights and 4 turns. (give out the chalk rulers and protractor sheets) · Get other pairs to test routes by writing instructions and putting a human roamer robot through the route. · Finally ask pupils to explain how they got on and if they had to adjust their instructions. Draw out how important trial and error is to this activity and reinforce the fact that it is ok to change a set of instructions in the light of a direction that went the wrong way.

· Trial and error is ok to adjust a set of directional instructions.	Print protractor sheets for all your pupils. Most able may be able to use a real protractor. You may wish to adapt the sheet for less able so it only includes 90 and 45 degree angles.	You can also explain that next week you are going to follow trails for each other on the Roamer World Program.	Metre sticks and board protractors Sheets Chalk Notebooks A dry day
Learning Objective Lesson 4	Lesson Plan
· Negotiating a set route · Writing Simple instruction strings that get increasingly more complex.	· Load from Roamer World Project Launcher in the routes section the subway route. This is good at this stage as it involves using 90, 180 degree turns only · Demonstrate how to move the roamer from one station to the next, point out the distances involved (13 & 16) marked along the top and sides of the subway map. Pupils can then estimate distances based on these overall distances. · Direct pupils to work in pairs each one giving instructions to move just one station to begin with and then swap over. Once they have completed this 3 times then they can move on to longer distances of two stations and then 3 & 4 etc.

· Writing a set of instructional commands to follow a direct route	You can move pupils onto other routes where they will need to use other more complex angles. (Cave under routes)		Roamer World Project Launcher
Learning Objective Lesson 5	Lesson Plan
· Creating a human roamer route around the school · Using a trundle wheel	· Group pupils into pairs give them a trundle wheel and a copy of the protractor sheet. They will also need a notebook or clipboard. · Remind pupils how to map a simple route across the classroom fd 1 = fd 1 metre on the trundle wheel. Get a pupil to record what you are doing on the board. · Now ask them to write directional instruction routes around the school. All schools will be different so make up your own before the lesson. I recommend asking pupils to show you what they have done after each route is completed. Try and vary your routes so pupils are spread out around the school.

· Using ICT roamer language 1. fd 2. Rt 3. Lt etc	Give SEN pupils shorter more simple routes Give ABLE pupils routes that have to go via somewhere		Protractor Sheet Trundle Wheels
