Strong Mathematicians show their thinking in different ways

We worked out the answer to 40 + 45.  Look at the different ways we showed our thinking. We all got the same answer!
Jack added all the 10's together and then the ones.  Great skip counting in 10's Jack!

Te Atawhai used her doubles and added 40 + 40 together.  That made 80.  Then she added on the 5.  80 + 5 = 85!
George used the equipment.  He made 45 and 40 with the place value blocks.  He added the 10's together and then the ones.
Strong mathematicians use equipment to help them explain their thinking.
