Mental computation comes alive


Ann was recently working with two Year 1-2 classes in South Australia, where she was presented with some student artwork. 
 

 “Hold on, “: she thought, “this is more than just artwork. It’s really helping the mental computation strategies come alive for these students.” When she went into the classroom of Lynn and Sue at Torrensville Primary School, she found that the ceiling was a celebration of mental computation strategies.

“We’ve been working with the Secret Codes,” said Lynn, “we wanted the strategies to come alive for the students. We had a week when we were working on doubles so the students made doubles glasses. They started to look for doubles with their doubles glasses and soon we heard comments such as ‘I see double see everywhere’. Students were doubling any number that they liked so they could extend the ideas themselves”.


The next strategy that Lynn and Sue introduced was the rainbow facts. “We used The Rainbow Fish to bring this one to life” they said. Number splitting naturally followed and as you can see below the students made characters doing the splits and chose their own numbers to split.



Congratulations to Lynn and Sue for your creativity and many thanks for allowing us to share this work.
