INVESTIGATING ODD AND EVEN NUMBERS

Today we were investigating odd and even numbers.

We discovered that if you can sort a collection into groups of 2,
then it is an EVEN number....

and if you can't and there's one left over,
then it's an ODD number.

We discovered that EVEN numbers end in a 2, 4, 6, 8, or 0.

ODD numbers end in a 1, 3, 5, 7, or 9.

So 36, 852 and 2,657, 126 are EVEN numbers and

47, 671 and 3,999 are ODD numbers.

So give us some numbers and we'll tell you whether they are ODD or EVEN.

Just leave them in a comment and we'll post about them!

GROWING WITH GROWING PATTERNS

Today our room was a 'patterning paradise'.
We had so much fun patterning, that we patterned for hours!
Mrs M couldn't stop us. We didn't even want to go out for Snack!

We were investigating GROWING patterns and we amazed Mrs M and even ourselves with what we discovered!
Can you work out the rule for each of these patterns?
Can you represent each pattern with a number pattern?
Can you apply the rule to tell what comes next?

Pattern 1:

Pattern 2:
Pattern 3:

Pattern 4: this one's tricky but if you apply the rule, you should be able to work out the starting number, even though you can't see all the blocks.

Pattern 5:

Pattern 6:

We kept this number pattern going all the way to 99 and we didn't have to keep applying the rule because we found a shortcut - a pattern in the pattern.

1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 _ _ _ ....

Can you keep it going? Can you see what we saw?

MORE GRAPHING FUN

1M,

Here are links to some great sites I found that

will help you display your data in a bar graph.

Here's the graph I created on this site after I entered in Tierney's data.
To save your graph just take a picture of your screen - press the 'Alt' key (beside spacebar)and the 'Print Screen' key ( top right of keyboard).
Then open up PowerPoint and paste it into a slide and save as a jpeg. Then you can upload it to your blog.

I created this graph with BJ's data at CREATE A GRAPH.

This site allows you to print or save. It also shows you some other types of graphs you can use to display your data.

HAVE A GO AT GATHERING SOME DATA AMONGST YOUR FAMILY AND FRIENDS AND USE ONE OF THESE SITES TO CREATE YOUR GRAPH.

And if you're feeling like a challenge, play this DATA PICKING game.

In this game you click on each person to gather data and add tally marks into a table. The word 'frequency' just means 'how many'.Then you choose the graph that represents your data. The tricky part is that it's not a BAR GRAPH, it's a PIE GRAPH. Want to find out what that is?.....Play the game!

'SURVEY SAYS'...OUR MATHS INVESTIGATIONS

Remember our post about A POLL NEEDS A...

Since then we have been

finding out about ourselves

as a class. We have been
ACTIVE

INVESTIGATORS.

After deciding on a question, we first had to GATHER the DATA.

We RECORDED the data using ticks or tally marks.

We discovered it was a good idea to write down names as well, so that we knew who we had asked.

But at this stage, it wasn't easy to see the RESULTS of our questioning. So.....

we had to be EFFECTIVE COMMUNICATORS and DISPLAY the DATA.

Some of us chose to DRAW a BAR GRAPH by hand and others chose to produce a BAR GRAPH on the computer by inserting a 'table' into a 'Word' document.

Now it was easy for us to see and INTERPRET the results of our surveys.

Our next step is to post about our learning on our own blogs.
You can access the results of Courtney's, Johanna's and Tierney's investigations by going to the sidebar, finding LABELS and then NUMERACY BLOCK.
All of our results will be posted by early next term, so don't forget to come back and check out the results!

GROWING PATTERNS

Today we explored GROWING patterns.

GROWING patterns do not repeat.

They GROW!

First we created our patterns. Some were GROWING, some looked like they were SHRINKING and some looked like they did both!

Then we took one part of our pattern away.

Others had to look closely at our pattern and work out the rule we had used to make our pattern.

Then they put back the missing part.

No-one was tricked.

WE WERE JUST ALL TOO CLEVER!

What ideas do you have for a GROWING pattern?

Make one at home. Draw it or now you can take a photo of it and email it to 1mgems@gmail.com

ALL ABOUT '8'

Where do we see '8'?
What things have '8' about them?
We went on a search.

A stop sign has '8' sides.

This shape is an OCTAGON.

'8' notes on a piano is an OCTAVE.

A spider has '8' legs.

So does an OCTOPUS.

Here is a rowing

'eight'.

And in our room we found...




'8' masks,

'8' pictures so far in our 'Dan The Flying Man' story,

'8' words under 't' on the Word Wall,

August - the '8th' month of the year,

'Alistair',

'Harrison' and 'Courtney' - all names with '8' letters




and '8' kites flapping in the breeze.

Here is a pattern Laura whipped up. It's also about '8'.
(You can read Laura's poem about '8' in the next post)

Where else do you see '8' ?
Go searching and leave a comment telling us what you found. Take a picture and bring it in or do the same as Laura and write a poem about '8'.

MRS M'S BACK AND WE DID 'GO MATHS'!

COOL!! That's what we said when Mrs M said we were working in our 'GO MATHS' books today.
It was our first time working in this book.

We felt very grown up!

We did some activities on patterning. We had to continue a pattern or draw in the missing part. It was REALLY easy because we do patterning ALL the time!

Are you a 'PATTERNING PERFECTO', 1M? Can you continue these patterns?

1.Let's start with an easy one.

Continue it on two places - they are........, .............
What type of pattern is this?

2.Now try this one - it's trickier.

What comes next?
This pattern is a _ _ _ _ pattern.

3. This one seems a little harder, but it's not.

Where will the stars on the next two wreaths be? Top? Bottom? Left? Right?

They will be ........, ...........

What type of pattern is this one?

4.You're a real PATTERNING PERFECTO if you can get this one!

Continue this pattern on for 5 places-........, ........, ........, ........, ........

Can you name this pattern in two ways?

It's an _ _ pattern or if you look closely, it's an _ _ _ _ _ pattern.

LET'S SEE HOW MANY OF YOU ARE A PATTERNING PERFECTO!

POST A COMMENT WITH YOUR ANSWERS!!

ALL ABOUT 5

What do we have '5' of? We went on a search.

5 fingers



5 very pink toes

5 oranges eaten by the very hungry caterpillar

5 dots on a dice

our school bag has 5 compartments

and every flower on this bush has 5 petals

Where else do you see '5'? Hear '5'? Here are some clues to get you going.

How many points on a star? Who's someone in 1M with 5 syllables in their name?
Post a comment with your discoveries about 5.
