This is my thinkboard for maths in Wk 10. This week, there was a question about adding big decimal numbers, the question was 23.345 + 3.953 = ?? I found this question easy and quick to complete but the challenge for me was making up a word problem. The thinkboard shows my working out, a diagram of my working out, a word problem that I made up and 10 other similar questions to the main question.
