My Solution for the Ti Kouka Maths Problem EPS
I am learning to use my maths knowledge and strategies to solve maths problems from the real world
Our school has a beautiful cabbage tree but it is constantly dropping leaves. Lots of children help at lunchtime and pick up these tough leaves that can’t be composted.
1. One lunchtime some students organised the leaves into bundles of 10. Why might they have done this?
I think they organised the leaves into bundles of 10 because its much faster to count and it wont take for ever.
2. One lunchtime some students made a tally- each stroke was one group of 10. Can you work out how many leaves were picked up?
How I worked how how many leaves were picked up:
I did 50+50+50+50+50+50+50+50+50+50+50+50+50+50+50+50+50+50+50+50=1008
3. The previous highest score was 466 leaves. How many bundles of 10 was that?
How I worked the number of bundles of 10 in 466:
100 is 10 tens, so 400 tens is 40 tens and 60 tens. The extras is 6 ones.
4. How many more leaves were picked up today than the last highest score of 466?
How I worked this out:
I did 460+500=960+40=1000+6=1006+2=1008. Then I did 500+40+2=542.
