As part of Engineers Week pupils from the junior classes made cool structures using spaghetti and marshmallows. As part of this work they discussed the 2d shapes and 3 d shapes that they were forming. The older classes discussed which shapes made a stronger structure.

  
  
  



Maths meets hurling!

Our challenge was to line out the pitch for the boys hurling match. We were trying to make the lines as straight as Mr Phelan can. We used maths to figure it out.

The two goal posts are normally left on the 21 metre line. Using a trundle wheel we measured the distance from one 21 m line to the other one. We wanted to put 5 flags between each corner flag, so we divided the length by 6. This gave us the distance between each flag. Then we used a tape to measure 8 m from the sideline. Each flag would be 8m from the sideline. So two teams worked on each side of the pitch and laid out their flags.

Trouble!
We measured to the wrong line and our overall length was wrong. We had measured 72m, but the actual length was 96m. Therefore we ended up using 2 extra flags on each side.

Result
We ended up with a beautiful, symmetrical pitch. 



    










Measuring Weight - Ms Moriaritys class

The boys and girls of 2nd and 3rd investigated ways of designing bridges as part of Engineers Week 2018. As part of their investigations they measured the weight that could be supported by each bridge. They learned how to use weighing scales and how to make reasonable predictions.

          
     



Maths Week visit

Aa part of Maths Week 2017, Offaly County Library invited Mr Breslins 5th class to the library in Tullamore for a coding workshop.

Laura from anyone4science.com talked us through reading and writing simple codes using simple keys. We then learned about ASCII code and translated our names into ASCII codes using ones and zeros. Finally the children got to make a keyring using white beads for zeros and black beads for ones. 
We wish to thank the library for their kind invitation to what was an enjoyable and informative event.
