This is what we have been doing in room three
and for me it has made maths a lot easier. We have been practising the strategy reversibility – don’t subtract add.
(The Math Problem)
Teone saves $536 to buy a new dvd player . The dvd player is $899.
How much does Teone need to save up to buy a dvd player.
$536 + $363 =$899 $899 – $363 = $536.
