Time Estamation

Today for Strand Maths we did a time estimation sheet. We had to estimate how long it would take us to writ 1-100, Read a picture book and 30 star jumps. It took me a while to write 1-100 and it was a bit hard. I thought it would take me 3 minutes to write 1-100 but it took me 2.42. I thought it would take me 1.00 to read a picture book but it took me 41 seconds. I thought it would take me 50 seconds to do 30 star jumps but it took me 20 seconds.  Most of my estimates were under 20 seconds away. I could improve my writing from 1-100 by practicing. my closest estimate was 18 seconds away. Here is my estimates.
