Symbaloo Webmixes are such a great way of keeping a catalogue of useful websites. You can see other ones for Maths, English, Irish, Music and Coding HERE.
This has been a good week for finding resources on the internet
for teaching maths. On Monday the Google Doodle celebrating
the birthday of John Venn featured an interactive animation which
I thought would be very useful to introduce students to
Venn Diagrams and specifically to
illustrate the intersection of two sets.
You can see that here.

Today on the @WeAreTeachers twitter feed I came across
the visually arresting Animated numbers on Datapointed.net
which one could use to help students visualize
prime and composite numbers.
These patterns are quite mesmerizing and demonstrate
the beauty of maths. I would use it to help students learn
about factors and to understand the difference between
prime and composite number.
I might also use it occasionally as a ‘drill’ where the student
would call out ‘prime’ or ‘composite’ so as to become familiar
with these words themselves.
I would also be interested in their hypnotic or soporific effects 😉

We have been using these games to practice our maths in class
1. Great Subtraction Practice
We are really enjoying this one.
2. Another game to practice subtraction.
Key in the correct security code
by completing a number of take away sums
and as a reward the student gets to design a superhero.
This game certainly has its fans in 2nd Class Room 6.
3. Challenge: Football Themed Two Digit Addition
Our football fans enjoy this one.
4. This one is a new addition.
Watch out because it gets quicker
and quicker as you go up the levels.

To know another teacher has found a website useful
is very helpful when sourcing
age appropriate educational websites.

At the moment the children are learning subtraction with ‘renaming’.
This methodology is required for example when you are doing a sum like:
The student starts ‘taking away’ the units and realises that they can’t take 5 from 3.
We are doing subtraction with ‘renaming’ in school.
We have done a lot of practical work using Dienes Blocks.
We are at the early stages of learning how to do these kind of sums.
At the moment, for homework, the majority of the class are getting
a worksheet of subtraction without renaming.
This has caused some confusion as the children attempted to ‘rename’
when it wasn’t necessary.
Identifying when a sum will need ‘renaming’ is a skill in itself
and one which we are working on!
More confusion can arise because some parents may have learned
how to do this kind of subtraction using the
‘borrow and pay back’ method.
Another factor that may confuse you is that ‘renaming’ is also referred to as ‘regrouping’!
You might find this Tips Sheet from the NCCA helpful:
or on the Maths is Fun website below where the methodology is clearly demonstrated:
Strategies we use – Bridging the Ten
I have found that the children who know their tables are completing these sums sooner than the children who don’t.
I am encouraging the children who find tables hard to use strategies to help them.
You might hear them talk, for example about ‘bridging the ten’.
Ask a child to take 7 from 10 and they will say 3 with confidence.
This is because they are very sure of ‘what makes 10’.
However when one asks a child a sum like 17 take away 9, they are less sure of the answer.
One of the solutions is for the child to learn the ‘make up’ of 20
and be as sure of it as they are of ‘what makes’ 10.
Again, we are working on this!
The other solution is that the child learns to ‘bridge the 10’.
Take that sum 17-9 again:
The children are fairly secure in the knowledge that 7 steps will bring them back to 10
‘Nine is one less than ten. So you add 7 and 1 and the answer is eight’.
Just in case you missed it…
I am reposting the link the the post on this blog on the importance of learning tables.
Thank you for your continuing interest and support.
Look what you can do with K’nex. Nice work Senan!
Learning Addition and Subtraction Tables is a very important aspect of learning maths in 2nd Class.
Adding and taking away tens and units is the ‘big deal’ in the second class maths curriculum. This is made so much easier if the children know their tables ‘upside down and inside out’.
It means when I go on to teach adding tens and units the children can focus on ‘the method’ and not on the ‘sum’. It can be disheartening for a child to get ‘the method’ right but the answer wrong because of a mistake in computation.
I realise the early tables can be very easy for children who have an aptitude for maths. Learning tables is like climbing a mountain – and we are in the foothills at the moment! I will be sending home tables for homework from the beginning of October. We have been revising adding and taking away to 5, thoroughly in school during the month of September.
The children can practise tables for homework in a variety of ways; singing the table, using their hands to keep them on track i.e. where they are in the table, lollipop sticks, number line and table book.
We use Joyce O’Hara’s cd: Joyce O’Hara’s Learn Through Song
I am sending home a laminated A4 page of the tables, in case your child does not have a table book. Please keep these carefully.
I will also make a lot of use of the addition square.
We start off gradually but we are working towards the challenge of a ‘Five Minute Maths Frenzy’!
Five Minute Maths Frenzy
The children use concrete materials to help us understand the maths we do in a ‘hands on’ and practical way. Each child has a Number Bag containing a number line and hundred square, a clock, unifix cubes, lollipop sticks, dice, pegs and a peg board. We also keep a dry board marker and a cloth in this bag, for working on individual whiteboards.
Initially I encourages the children to try Free Play with the contents of the bags. This is popular on wet days when we can’t go out to the yard. We can make patterns and constructions. We can also play dice games like ‘Race for 100’. One of the advantages of familiarity with the contents of the bags is that when we go to ‘work’ with them, the children are less inclined to play around with them, as they have had plenty of opportunities to do this already.
Here is some examples of the Free Play the children did today. The results certainly brightened up a rather wet lunch time for me. Can you spot the ‘smiley face’ by Zac and ‘teacher teaching the children’ by Kila? Can you see the imaginative ‘cup cakes’ and robots?
