My dd is sitting the St Michaels test and type 'K' are slowing her times down. I understand that at least 1 Barnet school use all 21 types, but St Michael's give no information out about the tests at all. Are there any tutors/parents out there who could help, as I don't want to waste time on them if ther are irrelevant!

Hi 2Girlsmum

I can't help you on St. Michael's, but I think the papers are GL Assessment, so they may well include Type K, and indeed all the HIKNOS types.

The reason kids find these particularly hard is because they are taught to do sums from left to right, and suddenly they are presented with "left, right, middle". Their brains are just not trained for it. When my son got stuck on these he found it helped to think of them - or even write them out in "normal sum order", so instead of e.g. ( 22 [ 12 ] 10 ), 22 ... 10 ... 12.

Someone (I can't remember who) once sent me the following helpful list of the variations in these questions on GL papers. Make up a few examples of each one, encourage her to think of them in the usual linear fashion (always remembering that there can be a hidden operation such as "add another number not shown") and she should speed up. She might even like to write a few examples herself - that can do wonders for kids' understanding of how a particular question type works.
Add
( 14 [ 26 ] 12 ) ( 11 [ 29 ] 18 ) ( 7 [ 21 ] 14 )

Subtract
( 22 [ 12 ] 10 ) ( 19 [ 8 ] 11 ) ( 27 [ 15 ] 12 )

Multiply
( 7 [ 42 ] 6 ) ( 9 [ 54 ] 6 ) ( 7 [ 49 ] 7 )

Divide
( 36 [ 6 ] 6 ) ( 42 [ 7 ] 6 ) ( 66 [ 6 ] 11 )

Double first number add second number
( 8 [ 27 ] 11 ) ( 4 [ 26 ] 18 ) ( 13 [ 33 ] 7 )

Add both numbers then double
( 7 [ 26 ] 6 ) ( 4 [ 14 ] 3 ) ( 9 [ 26 ] 4 )

Subtract then double
( 18 [ 26 ] 5 ) ( 11 [ 8 ] 7 ) ( 26 [ 14 ] 19 )

Multiply then double
( 4 [ 56 ] 7 ) ( 5 [ 70 ] 5 ) ( 6 [ 48 ] 4 )

Divide then double
( 32 [ 16 ] 4 ) ( 48 [ 16 ] 6 ) ( 84 [ 24 ] 7 )

Add both numbers then add another number
( 4 [ 14 ] 7 ) ( 9 [ 17 ] 5 ) ( 11 [ 19 ] 5 )

Multiply then subtract another number
( 5 [ 25 ] 6 ) ( 6 [ 49 ] 9 ) ( 4 [ 39 ] 11 )

Divide then add another number
( 24 [ 11 ] 6 ) ( 18 [ 13 ] 3 ) ( 28 [ 11 ] 7 )

Add then halve
( 14 [ 12 ] 10 ) ( 8 [ 11 ] 14 ) ( 26 [ 18 ] 10 )

Subtract then halve
( 18 [ 4 ] 10 ) ( 22 [ 7 ] 6 ) ( 32 [ 12 ] 8 )

Multiply then halve
( 6 [ 15 ] 5 ) ( 3 [ 12 ] 8 ) ( 5 [ 15 ] 6 )

Multiply then multiply by another number
( 3 [ 48 ] 4 ) ( 2 [ 40 ] 5) ( 4 [ 32 ] 2 )
Hope that helps.

I have just printed these brackets out for my child and have noticed a mistake. The second bracket I think should be
5 x 7= 35 x 2 = 70

Multiply then double
( 4 [ 56 ] 7 ) ( 5 [ 70 ] 5 ) ( 6 [ 48 ] 4 )

Am I correct?
