Partitioning Made Easy!

Check out these cool cats.  See if you can work out how they used this strategy to solve addition problems...

Ready, Set, Go!!!!  How can you add 8 + 6 using partitioning?  Show me!

How did they solve 8 + 6 using partitioning?

A new challenge:

Ready to solve 9 + 5...

How did they solve 9 + 5 using partitioning?

We're ready Mrs C!

There's no stopping us now!

See!

Slytherin - making maths easy!

Mrs C's Slytherin ALiM group have been learning about perimeter and area.  In fact, they are so clever with this that they are now experts and have been helping the rest of Room 2 with their learning of this.  Here are some photos of the Slytherin group in action...

This is the problem we started with - finding the area of a 4cm by 4cm square - (rectangle adapted for the purpose).

Making the  square with cm cubes 

Mrs C set us a challenge - of creating our own shapes then working out the perimeter and area of them.  Check out how we did:

Try and stop this clever crew!  Check out their solving below:

Partitioning like a Pro

Mrs C's stage 3 group are just getting way too clever at this partitioning business!

Here are some photos of them partitioning to make a tidy 10.

If your child is in this group please ask them to explain to you how they do it.

Enjoy the photos:

Krue went to the lolly shop and brought....

7 green gummy bears and 6 orange gummy bears...now...how to solve this problem with partitioning?

Why of course!  7 add 3 more makes ten, then you add the three left over.  Ta dah!  That's partitioning to 10 by splitting our second number up into parts.

Persia went to the dairy and brought 8 orange gummy bears and 5 green gummy bears...now to get partitioning!

Yup, you guessed it!  These whizz kids knew to add 2 to 8 which makes ten then add the rest on.

Cooper went to the dairy and brought 7 green gummy bears and 4 orange gummy bears...

That's easy Mrs C!  7 add 3 makes 10 with one left over = 11!

Can you work out what the word problem would be for this photo?

Were you right?

Stage 3 - learning to partition to 10, then add the rest on.

Mrs C's stage 3 group have been learning the number bonds that make 10:

0 + 10
1 + 9
2 + 8
3 + 7
4 + 6
5 + 5
6 + 4
7 + 3
8 + 2
9 + 1
10 + 0

Now, they are learning to partition the second number when adding to make a ten first ( this is a much easier number to add with!). Check out some photos of them working with this new strategy...

Slytherin Flying High

Today Mrs C's Slytherin group made paper planes and used our feet to measure how far they had flown.  Here are some snippets of our time together today:

Persia and Aniyah concentrating on making their paper planes.

Isaia and Jadyn enjoyed folding and bending the paper to try different designs.

Nearly done!

Here we go...up...up...and away!

Finished, here we are with our designer paper planes

Measurers with Skills

Mrs C's Slytherin group have been learning about measuring.  They have looked at 1cm on a ruler and explored how mm can convert to decimals, fractions and 0.5 is the same as 1/2!  Here are some photos of these measurement experts finding out the exact measurement between two lines.  They are so super clever and could explain how 9.3 is the same as 9 and 0.3 of a cm OR 93mm OR 9cm and 3/10.

These clever kids deserve a special mention for all of their super learning about measurement.

Check them out while they work:

Hmmm, is this shorter than 10cm?  What's this, it's not exactly on a number...oh no!  What do I do now?

Hmmm something makes me think those scissors are bigger than 10cm Aniyah!

I just love Jadyn's enthusiasm, he looks pretty relaxed about this measuring business...

Isaia, I think you're right.   It's come up a tad short.  What are you going to do now?

Check out this clever mathematician...if at first you don't succeed...fold the paper smaller!

Let's get measuring!

Persia measured the distance between her marks and wrote the measurement herself.  Well done!

Wahoo Jadyn, you clever thing.  Look at that accurate measuring.

This cool customer was fairly confident of her measuring and could explain how she got the measurement 21.7cm.

Mr accurate, 24.5cm and he remembered he could say 24.5 or 24 and 1/2 cm

Matthias you are loving learning through measurement and you are getting pretty good at it too.

The rest of Room 2 had to find out what our secret Slytherin group had been up too...
