# Where’s the party? Number Patterns for Grade 3

Hello to the Whitehorse gang!

As promised, I have uploaded the line masters for the task we did today.  It is intended to tie together experiences of skip counting by a number (4, 8, 12, 16, etc), describing a pattern rule (we started at 9 and counted by threes) and using a hundreds chart as a tool for establishing and visualizing patterns.

So the job was to help me find the party at 35 “something” street – the name of the street was erased by the dog prints made by my puppy Porkchop who walked on the invitation.

Of course you are free to change the numbers in any of these scenarios to make the problem more or less difficult.  Remember that we are to use number patterns to 1000 in the new curriculum, so you might even consider a street in which the house numbers start at 200 and grow by 10 or 50 or even 100 each time as a more complex problem for later in the year…

To start, you’ll need houses.  Print (or draw) at least 6 for each street.  Number 4 of them (use sticky notes so you can change the “house numbers” for subsequent lessons) and leave 2 numberless to suggest that the numbers continue – just like the counting patterns we know…

If you want to do the introductory tasks I modeled this morning, print off some trees.  Remember to leave 3 repeats of the pattern so that kids can predict the pattern rule for the street numbers before you cover a house-front or 2 with trees…

The invitation to the party is easily edited too, if you want to cover up the 35 and try another number instead.

Recall that the numbers I chose for the streets were:

A STREET – 4, 8, 12, 16…

B STREET – 9, 12, 15, 18…

C STREET – 2, 5, 8, 11, …

and we were looking for the street that had the house number “35” on it.

Would make an interesting challenge to change the party house number to 48… then there’d be 2 possible streets where the party might be held! (ooo – I smell common multiples!!)

Enjoy!
