Sequencing Roamer 1

This is a group activity for children who have difficulty getting the right sequence when pressing keys to make Roamer move.

You will need:

1 Roamer different coloured Roamer "jackets" 2 Clear Memory cards 2 Forwards cards 2 Backwards cards 1 of each number cards up to 5 2 Go cards

Write correct sequence on a board and discuss it to help children before starting this game.

Or


Sequencing Roamer 1

1. Five children sit in a circle on the floor. 2. Cards are placed face up in the middle of

the circle. 3. Choose a child to pick up the first card

needed to program Roamer (Clear Memory) which they keep hold of.

4. Work your way around the circle asking each child to pick up the next card needed until collectively they have made a program. This would be:

1st child Clear Memory card2nd child either Forwards or Backwards card3rd child number card (how many steps)4th child Go card


Sequencing Roamer 1

5. Ask the child who has not got a card to choose a coloured Roamer jacket, place it on Roamer and stand ready to program. (The jacket makes the game more interesting.)

6. Children with cards should now line up facing Roamer and child No. 5

7. They then hold their cards up to help the 5th child program Roamer.


Sequencing Roamer 1

8. The child chosen to program reads cards to help them press keys in the correct sequence to make Roamer move.

9. Roamer is programmed and moves. 10. Children return to the circle to repeat the

activity starting with a different child.

Notes: It is important when choosing cards that a workable card has been picked up. That is, cards must be sequenced correctly. Help may be needed at this stage.

Children will need the order of the cards written on the board in the early stages of this activity.It can be extended to 7 children by Roamer making 2 moves instead of 1 e.g. Clear memory, forwards 5, backwards 5, go. However, it takes much longer and there is not usually enough time in one session for everyone to have a turn at programming.


Sequencing Roamer 2

This activity assists children in programming Roamer using the Roamer cards to help with sequencing.

You will need:

1 RoamerAll Clear Memory cardsAll Forwards cardsAll Backwards cardsAll Go cards

Sit around a table with enough floor space nearby for operating Roamer.

Place cards face up in the middle of the table.


Sequencing Roamer 2

Each child in turn takes cards to make their own program for Roamer:

1st round

2nd round

3rd round

4th round

Clear Memory card

direction - either Forwards or Backwards card

distance - how many steps? - a number card

Go card


Sequencing Roamer 2

Children should be encouraged to place their chosen cards in the correct sequence and be able to say what they are.

When this task is complete, move on to programming Roamer by each child in turn placing their chosen cards to one side of Roamer. (If placed in front they will be in the way when programming a backwards move.)

The child then uses the cards to help them program.

Note: This activity works best with no more than four children at any one time, as they have to wait for their turn to program Roamer.


Number line game

This game will help children who need to become familiar with "forwards" and "backwards" and can also help with number recognition.

You will need to convert "six" on die to "zero".

Contents:

1 die6 number line boards6 coloured counters25 "stars"


Number line game

How to play the game:

Each player should have one number line card and a coloured counter placed on zero.

Highest number thrown goes first.

1. Throw die 2. Count spots 3. Match number on line 4. Move counter to that number 5. Say whether you moved forwards or

backwards 6. If you are correct you may take a star card.

The player with the most star cards at the end of the game is the winner.


Moving forwards 0 - 5

Use the Roamer mats or the equivalent

Make a number line 0 to 5. The space between the lines should be equal to Roamer's body length - 30cm which is the forward and back unit of distance.

Place Roamer on 0.

A child chooses a number from 0 to 5. Another child is chosen to try and program Roamer to stop on that number.



To begin with, write program on the board to help children:

Fill in the number when chosen. changing it as the game progresses. Place Roamer on zero before another child chooses a number.Children should be encouraged to say the program. After a while, some of the children should be able to program a simple move from memory.


Moving forwards and backwards (0 - 5)

You will need

Place Roamer on 0 to start.

Write:


Moving forwards and backwards (0 - 5)

A child chooses a number from 0 to 5, write that number in the program.

e.g. 3 is chosen:

Choose another child to read this and then program Roamer.

Remember to change the numbers on the board each time a new number is chosen.

In time the children will be able to program these two moves without reading them from the board.





Place Roamer on 0 to start .

Child 1 chooses a number

Child 2 programs to reach that number

Child 3 chooses another number

Child 4 counts steps either forwards or backwards to reach that number then programs Roamer to stop at that number


Moving to chosen numbers (0-9)



Place Roamer on 0 to start

Child 1 chooses a number

Child 2 programs to reach that number

Child 3 chooses another number

Child 4 counts steps either forwards or backwards to reach that number then programs Roamer to stop at that number


Sums game

When the children can program Roamer forwards and backwards to chosen numbers, without having to read the program, they wlll enjoy these sums games.

Children usually do not take long to remember that:

forwards is the same as +

backwards is the same as -


Sums game

It can be played exactly as Moving to Chosen Numbers (0-9) except that you write the program in sum form.

For example if:

Roamer is placed on 0 . . . . . 0 + =

A child chooses, say, number 2 . . . . . 0 + 2 =

All children are then asked for answer. Roamer is programmed to see if they are right.

Answer is filled in . . . . . 0 + 2 = 2

Next child might choose number 5, write . . . . . 2 + 5 =

This activity can be adding only, take away or finding the missing number.


Estimating distances 1

You will need:

1 Roamer0-9 number lineA start lineRemovable stickers

Place 0-9 number line on floor with start line adjacent to the beginning of the number line:

Place Roamer on 0 on number line. Program Roamer to move forwards 5 steps. Place Roamer on start line. Program Roamer to move forwards 5 steps. - Mark floor where Roamer stops.

(By moving Roamer in this way, the children can see that Roamer's steps are always the same.)Give each child a sticker to write their name on. (These will be used throughout the activity.)



Tallest child now stands on the start line and walks 5 steps. Mark floor where they stop with their sticker. Shortest child now stands on the start line and walks 5 steps also marking the floor where they stop.

Ask both children to repeat this task to prove that their steps are not always the same. They should stop in a different place to where their markers are.



Take the number line away.

Place Roamer on the start line and program to move forwards 5 steps. Mark floor where Roamer stops. (This wlll help the children estimate as hopefully the children wlll place their stickers before this sticker for numbers less than 5 and after for numbers greater than 5.)

Children, in turn now choose a number from 0-9 and all children, mark the floor where they think Roamer will stop. Roamer is then programmed to move to the chosen number of steps.



You will need:

1 RoamerA start line2 paper cups Secure the start line to the floor with tape or blu-tack.

Place Roamer on start line.

A child places paper cups (upside down) where they would like Roamer to stop.

Another child

a. estimates the distance in Roamer steps to the cups.

b. tries to program Roamer to stop between the cups.



You will need:

1 Roamer (the train) 2 chairs 1 long piece of string chalk removable stickers 3 pieces of card approx. A4 size.

Preparation:

Tie string to chair legs.

Write names of three stations on card e.g. Maidenhead, Twyford, Reading, - complete Roamer units apart.

Chalk a platform line (see diagram).

This is a safety measure to keep the children away from the string when it is not their turn.



1. Children put their names on their stickers. 2. Place Roamer (the train) on first station e.g.

Maidenhead. 3. Children, in turn, estimate the distance in

Roamer steps to the next station (Twyford) and then program to go forward to stop at the station.

4. Mark floor where "train" stops with their named sticker.

5. Place "train" back at first station until everyone has had a turn.

6. The winner is the child whose sticker is nearest to the target station.

7. Repeat game starting at the middle station (Twyford).


Estimating distances 3It is a good idea to remove all stickers before programming from the middle station to the last one. Otherwise it can be quite confusing - some children will already have their stickers at the end station when estimating from the first to the middle one.Remember to keep the children behind the chalk line when it is not their turn.
