Changing Number Facts into Problems to be Solved.

PROBLEM SOLVING
These problems were written by 2nd as a whole class activity over a few days. We turned the number facts they were learning in tables into problems to be solved.
Over the next few weeks the children will be doing this for homework. I will collect the best ones and then get the children to turn the problems back into number sentences.
Writing these short problems integrates with literacy also.

2-2=0
Jack and Jill went up the hill to fetch a pail of water. Jack fell down and broke his crown and Jill came tumbling after. How many children were left up the hill?
10-2=8
Emily had a party. She invited 7 girls from Room 6 and John and Edward Grimes.
Jedward had to leave early because they had to spike their hair!
How many people were left at the party?
12-3=9
The Three Billy Goats Gruff,
the Three Blind Mice,
the Three Bears
and the Three Little Pigs
all went ice skating in Storybook Land. The Three Blind Mice found it so tricky, they went home. How many animals were left?
3 + 3 + 3 + 3 = 12 animals were ice skating
-3 went home
12 – 3 = 9
How many legs have these 12 animals altogether?
How many ice skates?
How many ears? How many tails?
8-4=4
Eight children went to the playcentre in Zoom. Half of them bumped their heads and went home. How many children were left?
10-4=6
When Teacher was little she had a packet of ten crayons. She ate four of them. How many crayons were left?

A detail from Ryan’s colourful picture of the Northern Lights.

Multiplication as repeated addition

First and second class provide a window of opportunity to learn addition and subtraction tables. Second class is a fresh opportunity for the children to learn these tables. In the main, I found the children have learned tables to 5 very well. These will be revised and then there will be another chance to learn to later tables to ten . It is important to master these tables by the end of second because
• In third and fourth the focus changes to multiplication and division.
• If a child knows their simple number facts they can more or less their full attention to method when being taught new maths e.g. ‘renaming’ when subtracting two digit numbers.

Ways of learning

In school we practise these tables, in a concrete way, using lollipop sticks and unifix cubes from the Number Bags on our desks. We have been singing the tables along to music. Hopefully the children have shown you how we use our hands to keep us on track while saying the table. We also use the table book.

In school we use Joyce O’Hara’s Addition and Subtraction CD from
SEE THIS LINK FOR THE JOYCE O’HARA CD FROM ASHTON PRODUCTIONS

We say ‘one and zero make one’, one and one make two’
‘one from six leaves five’. In this way we use the same language as this cd.

Children learn in different ways. Many respond to working with concrete objects; lollipop sticks, cubes, smarties. Some children really pick up on singing or chanting the table. For some keeping track of their tables on their fingers (a kinaesthetic approach) helps.

If you feel your child is not getting enough homework
Some of you may find that replacing the written maths the children used do with learning a table makes for less homework. But remember the few days or so it will be a case of adding and subtracting one and two. This will be quite easy. The tables will get harder after that.

If you do want to do extra work with your child you could rewrite some number facts from the tables as problems. We are told that children find problem solving difficult in maths. This may sound difficult, but can take as simple a form as ‘I had two pancakes on my plate. Mum made one more. How many had I then?’

Many of the children are very taken with the idea of learning how to multiply. We are in second class and as I say multiplication is on the curriculum for third.

Between now and Christmas we will be doing a ‘blitz’ on addition and take away tables. For this reason these tables are the only maths homework we are going to do in the next month. Instead we will do the exercises in the Mental Maths workbook in during class.

But time is ticking on and in second class multiplication is taught as repeated addition. In class we will be learning about number patterns and learning to count in 2s,4s,5s,etc. and using the hundred square.

We will also use this Counting Rap to help us:
Counting Cadence

Based on the Counting Cadence song from
the Dr. Jean Feldman Kiss Your Brain CD

We’re the best, we’re number one.
Now let’s have some counting fun.
1 2 3 4 5 6 7 8 9 10 11 12

We are smart, we’re really cool.
Come on and let’s count by twos.
2 4 6 8 10 12 14 16 18 20 22 24

We are rockin’ you can see.
All together count by threes.
3 6 9 12 15 18 21 24 27 30 33 36

We’ve got the beat&we know more.
Everybody count by fours.
4 8 12 16 20 24 28 32 36 40 44 48

We can count and we’re alive.
Now let’s try and count by fives.
5 10 15 20 25 30 35 40 45 50 55 60

Skip counting is a kick.
You can do it-count by six.6 12 18 24 30 36 42 48 54 60 66 72

We’re on a roll-our brains are revvin’. Everybody count by seven.
7 14 21 28 35 42 49 56 63 70 77 84

We’re fantastic-doing great.
Come on now and count by eight.
8 16 24 32 40 48 56 64 72 80 88 96

Lookin’ good and counting fine.
Now it’s time to count by nine.
9 18 27 36 45 54 63 72 81 90 99 108

Skip count, skip count once again.
One more time and count by ten.

We are super, yes we are. Look out world, here comes a star!

You may find the following useful…Answers to questions asked at the P/T meetings

I was asked these questions at parent teacher meetings to date, and thought parents in general would find the answers of interest.

Are the children sight reading when they play the recorder?
I am teaching the children to sight read and read the ‘lines and spaces’
but generally, at the moment, I feel the children are playing ‘by ear’.

Could books be sent home more regularly for parents to see progress?
Certainly.
As you know the ‘Mental Maths’ and ‘Spellbound’ go home almost daily.
Occasionally I have sent exercises in ‘What A Wonderful World’, ‘A Way with Words’ and ‘Modern Handwriting’ home for homework. I have sent Alive-o home too.
The difficulty has been that the next time we go to work in a particular book, a number of children may be without it because it is left at home.
Certainly I will send home textbooks from time to time. Just don’t forget to send them back!

How can you help your child with problem solving in Maths?
Problem Solving:

The following strategies are useful in relation to problem solving
• Discussing the problem
• Rephrasing to make the meaning clearer
• Using concrete materials where possible
• Using smaller numbers
• Setting out problem on paper using diagrams, drawings etc.
• Estimating

Some teachers use the word RUDE to remind the children of problem solving strategies.
So the children are encouraged to Read, Underline key words, Draw, Estimate (Answer).
This is the simplest approach. ‘Drawing’ the problem can be very effective. It gives the child time to think and ptocess the information.

Another approach is
We LUV 2 C word stories!
Look, Underline (the key word), Visualise(draw), Calculate and Check.

In tandem with these approaches you could ask your child:

What do I have? (what info is given?)

What do I want to have at the end? (What am I being asked to do?)

How do I get there? (add or subtract or a combination)
From next year this will include the options to multiply or divide

When I am teaching addition and take away number facts, the children will have opportunities to compose problems based on the number facts. The children choose one number fact and express it as a number problem. These problems can be turn expressed as number facts by their class mates.

1. Number fact 10-7=3
Turn this into a problem
Problem: Ten ducks on a pond. A fox came along and frightened away seven of them. How many were left?

2. Problem: Seven bats hunting for insects.
Three went home to roost. How many were left?
This can be turned into a number sentence.

When children get used to doing these, they find word problems much less daunting.

This is a good website. It teaches a visual strategy for problem solving:

4. How do I help my child with comprehension?

When you read with your child check that they understand what they are reading by asking them questions.
I have noticed that when children aren’t observing the punctuation on a page they lose the meaning of what they are reading.
Sometimes, in the early days when children are doing comprehension exercises in school, they attempt to answer the questions without reading the piece!

1. To start with, I ask the children to read a piece of comprehension.
2. To read the questions underlining what they are being asked.
This means they will be reading the piece with the questions in mind. They will be reading with a purpose.
3. To read the piece again with the questions in mind…underlining what they think would be useful.
4. Then to go through the questions one by one, looking for the answers in the comprehension piece and writing down the answers.
As they get good at this, there is less need for underlining.

Maths – simple computation: addition/subtraction in Second Class

If you feel the need to supplement homework, these are some suggestions.

Learning simple computation (addition/subtraction tables to 10+10) really benefits the student in second class. Because when they go on to learn how to add tens and units with renaming they can concentrate on this new methodology because the addition and subtraction come easy to them.

We will be doing this in class. These websites may help you help your child.

The first  is an addition speed test.

In preparation for adding tens and units with renaming, this game might be useful.

This is a good site for practicing number facts and computation:
