Maths

In my learning log the recent thing I have learnt was my maths.  For maths we have been learning some strategies.  But the one strategy the group is learning is adding in groups of tens. e.g.
34+ __   = 81
44, 54, 64, 74, 84-3=81
 So I have 5 tens to to get to 84 and then -3 to get back to 81 and it =47
Here is a photo of my maths in my learning log.
