Today I used 'Place Value' and 'Written Algorithm' to solve math problems.
Firstly, I read the question - 'Leilani has already practiced for 24 minutes, 26 minutes and 17 minutes. She needs to practice 90 minutes. How many more minutes does Leilani have to practice?
Next I did 'Place Value'. First I did the addition of the ones which are 4+7+6=17. Then I did the addition of tens which is 20+20+10=50. Then I added the answer 50+17=67. Finally I subtracted 90-67=23.
Then I did 'Written Algorithm'. First I did the addition of the ones which are 4+7+6=17. I put 7 in the ones column and put 10 in the tens column. Then I added the tens which is 20+20+10=50 and I added 50+10=60, and I added the answer 60+7=67. Then I did 90-67=23.
Lastly, I checked If the answer was 23 and the answer was 23.
I like problem solving because it helps me to develop my math skills, but it was hard to understand.
