Maths National Standars Totu

25.05.11

Students to be tested: L, K, A, T.


L and K first example:
37 - 9 = ?
Both kids had huge gaps when counting backwards. They both got confused around 31, 30 , 29. Their first strategy was to count on their fingers. I tried to do a bit of ‘just in time’ teaching and tried to connect 35 - 10 = 25 and so on.

24 marbles shared between 4 people.
K shared them out evenly from one.
L went 5+5+5+5 = 20 then added one more each.


T and A

37 - 9 = ?
Took away 7 and knew there were 2 left over and knows 30 - 2 = 28.

24 marbles shared between 4 people.
A knew that 5+5+5+5 = 20 and that there were 4 left.
T thought it could be 6 and then tested his theory by taking 6 away from 24 4 times.

In conclusion, it was very easy to see who was below, at or exceeding the standard for add/sub and mult/div. Now what? I would like to talk with most kids and give them these 2 questions to see how they work them out. The bottom 2 groups need to be working up in the year 4 standard for numeracy so this will be a focus for me.
