Applied Maths

Applied Maths

by brendan / Tuesday, 13 November 2018 / Published in Subjects

Applied Maths.

Background

Leaving Certificate Applied Mathematics is a subject based on mathematical physics.  It is studied and assessed at Ordinary and Higher levels. Applied Mathematics essentially uses mathematics to solve real life scenarios in an applied way. For example, students will examine speed/velocity of incoming trains & likelihood of them colliding or the correct angle to fire a canon in order for it to hit a target.

The subject has a strong overlap with physics and of course mainstream mathematics.

Examples of topics studied are:

  • Projectiles
  • Hydrostatics
  • Collisions
  • Velocity

Student prerequisite knowledge.

Students who choose applied mathematics should have a strong understating of Higher Level Junior Certificate Maths, a good ability to problem solve and of course an interest in physics.

School subject timetable:

Students will have 3 single and 1 double class weekly.

Assessment:

Students will have regular class tests on topics encountered. The Leaving Cert exam consists of 10 questions of which students need only answer 6.

Career Opportunities.

Along with an obvious career path in Mathematics and Physics, students who study the subject can branch into engineering, architecture or any of the other sciences.

If your improvement targets were a playlist…woul If your improvement targets were a playlist…would they actually help you progress?Using your SSE Feedback Tracker is about more than hitting play — it’s about choosing the right tracks.

🎯 Quality feedback deserves quality targets.
The best targets are:
✔ specific
✔ clear
✔ focused on one skill or topic
✔ easy to act on

🎶 Your “Improvement Targets 2026” playlist should sound more like:

✅ “Practise algebraic fractions — 10 questions, twice a week”

not ❌ “Revise maths”

and 
✅ “Use PIE structure in my paragraphs”

not ❌ “Improve English”

📘 Students: use your Feedback Tracker to turn comments into clear next steps.
👨‍👩‍👧 Parents: ask your child what’s on their improvement playlist — not just the subject.

Vague targets don’t move the needle.
Clear targets change the track. 💪

A fantastic day out for our U14s at the Munster Ru A fantastic day out for our U14s at the Munster Rugby Blitz in Fethard 💪🏉
Four games, four wins — a superb team performance. Outstanding tries from several players and valuable game time gained by others, showing great depth across the squad. A lovely bunch of lads who represented themselves and the school brilliantly. Well done to all involved! 👏

On Thursday, January 15th, our TY students attende On Thursday, January 15th, our TY students attended the Revive Conference at the SETU Arena.
The day was filled with prayer, engaging activities, uplifting music and plenty of fun. Now in its second year, the conference once again proved to be a memorable experience, with Fr John Harris delivering an inspiring keynote address.
The students thoroughly enjoyed the day, and for many it was a truly unique and meaningful experience. We are especially proud to have 30 students taking part in the John Paul II Awards this year as they work towards achieving their Gold Award 🙏✨
Well done to all involved!
Unfortunately our U17s bowed out of the Munster Ju Unfortunately our U17s bowed out of the Munster Junior Cup today after a narrow 2–1 defeat to Carrigaline.
The lads were unlucky to come out on the wrong side of a very even contest, producing some excellent passages of intricate play throughout. We conceded five minutes before half-time but responded superbly just 90 seconds later, with Alfie Ryan firing home the equaliser.
Despite creating several good chances in the second half, we couldn’t find the breakthrough and were punished when Carrigaline scored on the break.
Huge credit to the team for battling right to the final whistle, with standout performances from Daniel Doyle, Anderson Dube and Sean Lyons Mullan.
Well done to the entire squad on a tremendous season, and best of luck to those making the step up to U19 schools football next year 👏⚽
We look forward to welcoming our incoming 1st Year We look forward to welcoming our incoming 1st Year students to De La Salle College for their entrance assessments, taking place on Saturday January 24th from 9am–12 noon.

There will be a short Parents presentation in the College Chapel from 9.10-9.50am

These points reflect consistent effort, positive behaviour and the valuable contribution these students make to our school community every day. It’s important that hard work, kindness and commitment don’t go unnoticed, and today was a small way of saying well done and thank you for your efforts.

🔥 FEEDBACK = YOUR GAME PLAN Your SSE Feedback 🔥 FEEDBACK = YOUR GAME PLAN

Your SSE Feedback Tracker is like a game dashboard:

🟥 Weak Spots show where to focus
🟧 Confidence Check shows what’s improving
🟩 Next Moves tell you exactly what to do next

🎯 Quality feedback deserves quality targets.
Not “revise more”…
But what, how, and when.

❌ “Improve English”
✅ “Use examples in every paragraph”

❌ “Work on timing”
✅ “Use a timer for every exam question”

📘 Students: specific targets = faster XP, real gains.

👨‍👩‍👧 Parents: ask your child what their next move is — not just the grade.

No guessing.
No vague goals.
Just a clear plan to level up. 💪
