A look back at Science in 2015 in 3rd Class

   

Third class were also very lucky to have a visit from a group of Abbvie staff during science week. We were shown how to work as scientists. We carried out tests to identify materials. One lucky pupil got to dress up as a scientist. We learned a lot about the work of scientists.        

Maths Puzzle

 Chocolate Maths

chocolate

We tried this in our class and it worked. See if it works for you!

First of all, pick the number of times a week that you eat chocolate. This number must be more than one but less than ten.

  1. Multiply this number by 2 (just to be bold).
  2. Add 5 (for Sunday).
  3. Multiply it by 50.
  4. Add 1750.
  5. Add the last two digits from the year you last had a birthday. So if your last birthday was in 2009, add 9, if the your last birthday was in 2011 then add 11.
  6. Now subtract the four digit year that you were born.

You should now have a three digit number. The first digit will be your original number i.e. how many times you eat chocolate each week. The next two digits give your age.

February Maths Puzzle

 

 

Tilly’s Transport Teaser

Tilly has a big problem. She needs to row her pet cat, Casper, her pet mouse, Marcy, and a year’s supply of cheese to the island where she lives.

However, she can only transport one thing at a time with her in the boat.

If she leaves Casper with Marcy, Casper will eat Marcy. If she leaves Marcy with the cheese, Marcy will eat the cheese. It doesn’t     matter which side of the water she leaves them—the result will be the same.

 

How can Tilly bring Casper, Marcy and the cheese to the island without any trouble?

A Puzzle to Ponder

A woman went to a hardware store to buy something for her house.

She asked about the price.

The shop assistant was very helpful and told her that

1 cost 12 cent

48 cost 24 cent

I wonder what did she want to buy.

Think about it. Ask your parents to think about it and maybe you will solve the puzzle before the end of September.

If you figure it out, write your answer on a piece of paper and give it to Mrs Mc Gowan or Ms Coyne before the 30th of September. Remember to include your name with your answer.
