Ballast 2 - maths!

Yesterday, we tried doing the maths puzzle ballast. That time, we could choose any numbers that we wanted. Today we did the same puzzle, except the numbers were already chosen. we had to find the part of the boat that would sink. Here are the numbers.

 

I tried doing the first one by writing all the possibilities down in my book, like 2x3, 2x4, 4x5 etc. Then i added the other numbers: if I was trying 2x3, i'd add 1, 4 and 5 together. The answers to both of those weren't the same, so I tried the rest. none of those worked either so that meant that one is the part that would sink.

Now i did the same with the second and third parts, and there were answers.

I think this puzzle was really fun and it took me while to actually understand what I was supposed to do. It took me ages to find the answers to the problem, and I was really confused when the first one didn't have a possibility because I forgot there was one that didn't work. 

Ballast 1 - maths

Today we tried a maths puzzle called ballast. I chose five numbers: 3, 5, 0, 2 and 4. The problem is all about balance. on side of the boat its multiplication and the other side is addition, and in the end the total numbers have to be the same.

2 x 4 = 8, and on the other side 0+3+5= 8 as well! and yeah that's how I did the puzzle!

Heres a template if you want to do it by yourself:

maths pickle: blotch!

This week we have been trying out different ways to solve a maths pickle activity blotch. I found it very confusing and difficult to do in the beginning, but near the end I think i finally understood it. 

The first puzzle had 25 blocks. I tried solving it by using 5 and 20, but of course that didn't work. When you colour the number in (in this case 5), you had to surround it. then, if the number of squares that were surrounding it weren't the same as the number (5), colour some other ones. Then I did the same with 20, that didn't work so I used 18 instead and YAY it works!

It was really difficult because sometimes both numbers had to use the same blocks to surround them and that wouldn't work. 

The finished page wasn't very attractive because I kept choosing different numbers after I already started coloring in the blocks.

week five term 2!

writing!

this week for writing, Mr. Wood told us to try and write a 50 word story. I found this really fun because I already had an idea of what I was going to write in my head. my first try had 79 words which is very far from 50 :") because it was so long, I had to try and shorten it. it was very hard to get rid of words and make it 50 words long and I only managed to get rid of 10. Here are my first and second tries!

numeracy

this week we also did a lot of maths work. I learnt how to subtract and add fractions. here is a slide with how to do subtraction with fractions!!
