Number of the Day

Today at maths our number was 73.   We have to:

1. half it, 
2. tally mark it, 
3. write how many 10s and 1s in it, 
4. write what number comes before and after,
5. round it to the nearest 10 and 100,
6. double it,
7. write what number is 10 before and after it,
8. write a family of facts,
9. write a word problem whose answer is today's number
10. and write if it is an odd or an even. 

Our number was odd because 3 is an odd number.
