### Prompt Cards

These two group activities use mathematical reasoning - one is numerical, one geometric.

### Consecutive Numbers

An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.

### Exploring Wild & Wonderful Number Patterns

EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.

# Train Carriages

##### Stage: 2 Challenge Level:

I was on a train the other day and I was looking out of the window as we went through a station and I saw lots and lots of carriages waiting in another line. They were going to be linked together to make a new train going on a long journey - so I thought !!

It was then that my train went round a curve in the track and I looked out of the window and saw the front of my train and quickly turned my head and saw the back of the train.

After a few more miles I had seen that my train had ten carriages to make up the whole train.

I thought back about the carriages I had seen at the station and wondered about making them into several trains.

I thought my train was rather special having ten carriages so I want to put this challenge to you all.

1. Suppose there are $24$ carriages.
2. They're going to be put together to make up some trains.
3. The smallest train you are allowed is one with two carriages.
4. You must include at least one "ten-carriage train".

That's all really.

Here are some to start you off.

You could draw these.
You could use cubes/ beads/ boxes or whatever to stand for the carriages. So it might also look like:-

Next:-

and if you used squares or cubes it might look like:-

So now it's your turn. See what different train arrangements you can make.

Remember the four "Rules" above.

It would be good to think if you have been using some kind of special way of getting new ones. Maybe you've found a pattern that helps you get lots of answers?
