Homework complete a maths 10x10 in 2 mins

I have chosen this challenge because maths is my favourite subject I love to work with numbers and I enjoyed completing this 10x10 graph in 1:45 seconds. I had to practice about 5 times before I new I could complete it the graph in time. I had to remember my 7 and 8 times because they were the last numbers I did.

I will now tell you how I completed this graph
1.complete the 2s 10s 5s and 1s
2.complete the 3s 9s and 4s
3.complete the 6s
                                                                          4. finally complete the 7s and 8s
