Figure it out-Maths

Yesterday and today, my class were focusing on word problems from the Figure it out books. The page I work ed on was the page about Listing factors.

I listed all the factors from 1-20. I found that there were numerous patterns in the factors I listed. I also found that there were eight numbers that only had two factors. All those numbers are prime numbers, (235711131719). Fun fact if you don't already know, Prime numbers is a natural number greater than 1 with no positive divisor. Prime numbers has exactly two factors, 1 and itself. I now know the factors of all the numbers from 1-20. Here are the factors for each number.
1-1,
2-1,2
3-1,3
4-1,2,4
5-1,5
6-1,3,6
7~1,7
8-1,2,4,8
9-1,9
10-1,2,5,10
11-1,11
12-1,2,3,4,6,12
13~1,13
14-1,2,14
15-1,5,15
16-1,2,4,8,16
17-1,17
18-1,2,3,6,9,18
19-1,19
20-1,2,4,5,10,20

I also completed the next page which contained decimal problems. I found the decimal problems challenging and I think I rose to the occasion when I was given the questions. I really enjoyed working with the figure it out book, it really got me thinking hard!.

Great learning there Luisa and I knew you would have enjoyed the activities in that book because one of your goals is to work on Algebraic problems.
