### 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.

# Street Sequences

##### Stage: 1 and 2 Challenge Level:

Let's look at a street!

Most of the streets around here have their numbers going in order from one side of the street to the other - so that odds end up on one side and evens on the other.
So here's what is could be like:

Looking from above the numbers could appear as:

Well you can imagine walking down this street and adding the house numbers in various ways.

and carry on as far as you can.
Explore the answers you get for these additions. What do you notice?
Can you explain why?

If you want to go a bit further with this you could change the grouping of houses in different ways. How about:

A.

Or:

B.

But maybe the houses are already grouped in some way - like all semi-detached:

Then one side of the street the totals are: 4, 12, 20, etc
and the other side are: 6, 14, 22 etc.

You could continue this and explore it further.

Some streets have terraces of three houses together:

and some have fours:

You can explore the addition of these groups too!
