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.

Learning strategies

One way that we are learning during MST time is to repeat other student's strategies and ideas. We do this to make sure we are actively listening to each other and we understand what they are saying. This audioboo recording is of MST group 1 listening to each other and repeating a multiplication strategy. Remember to leave a comment if you think we've done a good job!

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.

Photos of MST people using multiplication strategies

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.

Reflections on our learning - end of week 4

At the end of week 4 (Friday 31 May) we completed a reflection sheet about using part-whole strategies to solve addition problems.
First we went through the different strategies, ticking the ones we know that we can use.  We put 1/2 next to the strategies we think we can use but are not confident with yet.
In the first box we wrote the strategy that is our favourite to use, the one we are most confident using.  In the second box we wrote the strategy (or strategies) that we think we need more practise using.
