This week, dolphins have been working really hard to develop their place value skills. We have been using diennes, counters and other tens and ones equipment, to make 2 digit numbers – then we talked about the numbers we write and what they mean. We used arrow cards to show the values of the digits when we pull them apart (partitioning). 

We have used our knowledge learnt so far to solve addition sums. Finally, we have discovered that we can write adding sums in a different way, we can put the ones on top of each other and the tens on top of each other, then we go down the sum to add together the ones, then the tens. What a lot of tricky learning we’ve done. Here are some games we’ve enjoyed which will help with your understanding.
