Uimhreacha príomha – Prime numbers

Eratosthenses was a Greek mathematician who figured out that to find all the prime numbers between two and some large number, you need to remove all the multiples of each number between two and your large number. Start by pressing “2” (skip over “1”), and you’ll see all the multiples of two eliminated: 2,4,6,8, etc. Next, click on “3” and so on. At some point the program will stop, and all the prime numbers between 2 and 400 will be coloured red. Can you guess the biggest number you will need to click?

Maths Trail (Step 4 Maths)

Last week all of the Senior Class did an outdoor/indoor Maths Trail.

We were split into groups of threes and fours. In my group there was myself, Siobhán and Rosaleen. We were Goup 2.

Everyone got a measuring tape and a sheet with pencils on it.

We (my group) started on Question 1, which said to measure the width of the front door.

Some of the questions were quite  easy: measuring from the front door to the gate, for example.

We had to estimate all of  the questions before we answered them for real.

Once we answered all the questions we ran to the teacher for her to correct it but we got one of the questions wrong so we corrected it and brought it back to the teacher.

We came second! Amy’s team cam first!

Tá na páistí ag foghlaim an topaic ‘Am’ trí  cluichí éagsúla, mar shampla ‘Cén t-am é a Mhac Tíre?’, ‘It’s Time For Fun’ agus ‘Don’t be tardy for the party’. Imríonn siad na cluichí I ngrúpaí agus déanann mé fhéin agus Múinteoir Lorraine “team teaching” leo.
