This week, Rhino class have been learning about calculating perimeter.

When adding together a series of numbers together, please encourage your children to list, pair, reduce and then add. This is when the children list all measurements as an addition and then match pairs to add together to create a second but reduced list of numbers to add. The second, reduced list should be much easier and quicker to add together.

E.g.

list:              6 + 4  + 7 + 3 + 8 + 4 =

Pair:          (6 + 4)  + (7 + 3) + (8 + 4) =

Reduce and add:     10  + 10  +  12  = 36
