Odd and Even numbers

What do we know about odd numbers? What do we know about even numbers? Over the last week we have made a few discoveries! Check them out and see if our discoveries are correct!

 Discovery #1 = odd + odd = even

 Discovery #2 = even + even = even

 Discovery #3 = odd + odd + odd = odd

What do we do in MST?

What happens during MST time?  It is a bit of a mystery if you are not involved in one of the groups.  The following videos are of each MST group.  The videos are clips of a normal, everyday session :) The videos were taken on an ipad, so the sound is a bit hard to hear sometimes.

MST group 1:  Olivia, Harlem, Xzaviyah, Zeplyn and Zyprus.

MST group 2: Renee, Manaia, Miracle, Te Winika and Fonua.

Part-whole strategies

Over the last week both MST groups have been learning a new addition strategy.  The groups are learning to split numbers to make 10 (or another tidy number).

Here are some fotobabbles from the MST 2 group, showing how they can use different strategies to add numbers together.

Te Winika's strategy to add lots of numbers

Today Miss Bolton gave the MST 2 group a problem to solve. Everyone shared their solutions. Miss Bolton recorded Te Winika's explanation because it was a good way of using adding to 10 to help solve a problem and it was an example of an early Stage 5 addition strategy. Listen to the Fotobabble to hear Te Winika's strategy.

Multiplication Strategy - Repeated addition

We have been learning to use addition as a way to solve multiplication equations.  Here is a recording of MST group 2 explaining how to use repeated addition.

Fonua is using groups to solve the equation 6x6.

Te Winika was using his memory of a times table poster in his class to help solve the equation 4x8.

Xzaviyah and Zyprus have used groups of counters to help solve their equations.
