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!

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...

Krue can count in 10s up to 100!

Mrs C has been challenging us again!  Here is a video of Krue blasting counting in tens out of the water!  Good on you Krue.
