Nollaig Shona ó rang a cúig! We had a blast auditioning for our parts, learning our lines rehearsing and performing our Christmas play for our parents, extended family and friends. Our hard work over the past weeks really paid off. Maith sibh a bhuachaillí!

Congratulations to our two Rang a Ceathair boys who proudly earned the very first pen licenses in the class! Their excellent handwriting, neat work and consistent effort have truly paid off. Well done - keep up the great work!

Rang a ceathair spent the last three weeks bringing history to life by building Motte and Bailey castles using recyclable materials in art. After learning about the Normans, they worked in groups to design and create fantastic mini medieval worlds. It was a huge success!

Rang a ceathair enjoying lots of fun and mesmerising experiments this year for science week!!

Well done to all the boys who made a recycled Christmas decoration for the DLR competition. They look fantastic!

Our Dienes Blocks really help us visualise the numbers when we’re adding two-digit numbers together.

We recently finished our first novel, The Owl who was Afraid of the Dark by Jill Tomlinson. The boys made their own clay owls, which now have their own nest in our classroom.

Amazing artefacts for our school’s timeline & the annual historical fancy dress.

Amazing builds at our school’s weekly LEGO Club!

This test was a very effective way to show the importance of hand washing!

We watched as the gummy bear grew in water over a few days. This process is known as osmosis.

Chemical Reactions, Cocoa Powder Test and Coke & Mentos

Magic Pepper, Microscopic Views & Dancing Raisins

The boys watched the reaction when they dipped a cotton bud with washing up liquid into milk & food dye.

The boys have been learning about light and how different items can be transparent, translucent or opaque. They tested some items in the classroom using torches.

The boys made rainbow spinners to show how the colours of the rainbow can merge together to make white light. Great job boys!

We placed cress seeds in two different cups, marked ‘A’ & ‘B’. Both cups had cotton wool and water. The only difference was light exposure; we put Cup A on the windowsill and Cup B in the cupboard. The results were very interesting!

A great experiment to show how plants drink water.

The boys made terrifying cakes this year for our annual scary cake competition. The judges had a tough decision choosing the winners!

Congratulations to this boy who won this year’s spooky poetry recital in Rang a Dó. The boys learnt a variety of poems - Witch Witch, It’s Halloween, Skeleton Parade & Happy Halloween .

There was a fantastic turn out, on 15th October, at our weekly WOW ( Walk on Wednesday ) from Cuala for National Walk to School Week. Well done boys!

Well done to everyone who took part in this year’s GOAL Jersey Day on Friday, 10th October. We managed to raise €200 for such a great cause!

The boys are enjoying using our schools’ new skipping ropes. Each week they are getting better and better!

We are enjoying rehearsing for our upcoming Christmas Carol Concert.

Rang a 3 really enjoyed history week. Lots of the boys brought in artefacts and joined the whole school history timeline in the yard.

We are so lucky, at Harold Boys’ N.S., to have so many wonderful SNAs. It was nice to show them how much we appreciate their work on 25th September.

The 4th class had a fantastic day visiting the National History Museum, exploring exciting exhibits and discovering fascinating facts about the past. Everyone enjoyed the trip and came home full of stories and new knowledge.

We have started playing hockey this year. Our coach Ben from Avoca hockey club taught us lots of new skills and we really enjoyed playing a new sport.

Every Friday we do Art. The boys have made some great pieces so far this year.

The boys did a great job making friendship bracelets with Rang a Sé, using loom bands.

We recently explored our local area - Dalkey.

We are lucky to have Dalkey Library right on our doorstep. We, in second class, go up every second week to borrow and return books.

We had a great debate with third class. The motion was Homework Should be Banned . Both classes made great arguments. Maith sibh!

Many thanks to the boys in Rang a Sé for creating such a fun obstacle course for all the other classes to try.

Welcome to all of our new boys in second class.

Well done to all the boys who participated in Walk to School Week 2025! The boys ditched their cars this week and opted to walk, cycle, scoot or park-and-stride to make the most of the dry Autumn weather and help the environment while they were at it. Our Green Schools committee kept a record of the boys who walked each day and compiled our data in a colourful bar chart. Maith sibh a bhuachaillí!

Rang a cúig got Science Week 2025 off to a flying start by creating eardrum replicas to explore how sound waves cause the eardrum to vibrate. We have had lots of fun learning about the human ear and sound. Stay tuned to see what exciting experiments we explore next!

Rang a cúig had a blast planning and creating some fabulous bridges using only dry spaghetti and glue. The boys put on their STEM thinking caps and came up with some exciting designs before bringing their bridges to life and testing their durability using a bucket filled with sand! We definitely have some future engineers in our midst!

The boys had lots of fun making their scary cakes and showing off their creativity for our annual Scary Cake competition. Well done to everyone who entered the competition and a special comhghairdeas to our class winner and overall school winner. Maith sibh!

The active committee ran a whole school competition for our new Active Flag slogan for 2025/2026. Each class had 3 winners. The committee then voted on the slogan 'We were made in 1901 to be active, sporty and have lots of fun' as the overall winner. We are very happy with our new Active Flag slogan for the year. Go raibh maith agaibh gach duine.

Rang a 6 had a great time playing in their GAA league. Well done representing your school! We are all very proud of you.

The boys were all encouraged to walk to school every day. A survey was carried out and 2nd class had the most students walking to school. Maith sibh rang a 2!

In September 6th class ran an obstacle course for the whole school. The boys really enjoyed it. Maith sibh rang a 6!

Tús maith leath na hoibre !

We had a great debate about uniforms with second class on Thursday. Maith sibh buachaillí!

Last week we drew our school and this week we made clay models of our school. We will paint them next week.

We have been learning all about animals. We went on a mini beast hunt around the school. We found many invertebrates including spiders, earthworms, snails and wood lice. We examined, identified and drew them back in the classroom.
