In Maths we have been learning about making maths questions from a picture.First we looked at

the pictures and some made strategy about the tyres. Then we did asking maths questions and writing
maths questions about the picture of the tyres after finishing that we did blog commenting on the picture.
I found it is hard because I can't find how many tyres are there.I found it is easy because my teacher told
it is easy to do this ,do time tables it will be easy to do that.
