Reversed Hundreds Chart With Missing Numbers

What I also wanted was to be able to have a reversed hundreds chart. I was trying to figure out a way to create using Excel but although I could create the numbers, I couldn’t figure out how how to get the missing numbers.

Then I found this site.  It gives lots of different options.

You can have straightforward missing numbers and there are lots of fonts and colours to choose from. Then you can just click randomise to give you lots of different grids using the same options.

However, it is the “Edit Numbers” bit that really excites me!

Click on that and you get this pop up:

As you can see, you can use negative numbers and decimals and even change the increments. So by starting at 100 and setting the increments at -1, I have what I am after.

Multiplication tables

4x Table

By starting at 4 and choosing an increment of 4, I can take the 4 x table all the way to 100 x 4.

One thing that struck me by looking at it, in this format, was that I realised why the 4 x table has the last digit 4,8,2,6,0, pattern running through it.  4×5=20 and so you are adding 20 to 2 to get to 24, 20 to 8 to get to 28, 20 to 12 to get to 32 and so on.

What else might your children notice?

What questions might you ask?

In the table are the numbers: 12, 112, 212, 312.  Would 412 be there if we carried on? Why or why not?

 

 

11 x table

What do you notice here?

Take a look at any 3-digit answer where the two outside numbers add up to the number in the centre.  In all these cases the two outside numbers will be the number of times 11 goes into the three-digit number.

For example,  594, 5+4=9,   and 54×11=594

If you have a 3-digit number where the two outside numbers do not add up to the number in the centre, then take away 1 from the first digit in order to work out how many times 11 goes into the whole number.

For example, 836,   8+6=14, so take 1 away from the first digit,  76×11=836.

You can use this information to help you you multiply two-digit numbers by 11.

For example 35,   add 3 and 5 together to make 8 and your answer will be 358.  so 35 x 11 equals 358.

For example 38,  add 3 and 8 together to make 11 and your answer will be 418.   What you did here was to put the 11 in between these two numbers, but then to add Decrease the number in the hundreds column by 1. After all, multiplying by 11 is just multiplying by 10 and then multiplying by 1.By doing this as a column addition and you’ll see what I mean.

Take a look at some of the other tables and see what else you might notice.  Let me know what you spot in the comments area below.

 

 

Some other websites which allow you to print off a free hundreds chart.

HomeSchoolMath.net

https://www.homeschoolmath.net/worksheets/number-charts.php

On this page, you can make a variety of pre-prepared charts but towards the bottom of the page there is also a “Number Chart Worksheet Generator”.

This allows you to create hundreds charts which skip numbers and you can also choose to highlight every, for example, 5th square.  In this example, I have chosen to start at 3, make my increments 3, and hight every 2nd square.

The obvious thing it shows is the 6 x table, but what else can you see?

I found myself adding up the digits of the answers.  What do you think I discovered?

 

 

 

 

Other types of hundreds charts

One website I enjoy using is http://www.math-aids.com/ . you can use it for free which I did for many years but then decided that there is so much on here to explore that it was really worth paying the subscription fee. This gets rid of all the adverts and gives the site a much cleaner feel.  I think the downloads are quicker as well.

Here are some of the other hundreds charts you can get.

Create letters of the alphabet.

 

Is this useful?  Let me know any ideas of how you might use it.

The one thought I had would be to get children to add up the coloured numbers and see which were the most or the least.

Online Fractions Games

Online Fractions Games

Fractions are much easier if you have a good visual understanding of what is going on so online fractions games are an excellent way to explore fractions.

Consider bookmarking this page as there are a lot of links on this page. (Ctrl+D).

Topmarks

One site that I have been using for many years is Topmarks. This has grown and been kept up to date. The graphics are simple and straight-forward and the games fill the screen – unlike some older sites when they have not been updating the resolution as time has moved on.

Some of the games are embedded from different websites, for instance, the BBC allows you to embed some of their games into your own website so you can see that the style of these games is quite variable.

Other games are flash-based and many people no longer have flash enabled so they have a helpful guide to show you have to enable flash if it is not working on your computer.
Games for KS2 include:
Fraction Matcher

In this game, you can play the games against the clock if you want to. There are lots of different levels that you can choose from. This starts with very easy – halves, quarters, three-quarters, and by level 8 it is much more challenging as you can see here.

Level 8
There are lots of games on this site but let me just pick out a few.

One is called Fraction Beach in which you get buckets of sand when you get a correct answer.

There is an interactive tutorial called Proper Fractions – it has pictures of ducks on the front of it.  Cartoon characters explain what is happening and ask questions. This activity is aimed at 9 to 10-year-olds.

Another game that looks interesting is called Converting Fractions to Decimals. This is a futuristic mission game where you need to crack open the vault using your knowledge of fractions and decimals.

In Decimals Jeopardy you can play in teams or on your own against the clock.

When playing Treefrog Treasure, you have to collect jewels and in this one there are lots of different levels as well.

For those children who like the BBC characters Dick and Dom, there is an equivalent fractions game which includes some rather rude noises! Here is a video of me having a go at playing it.  Can you bet my score?

Click here to try the game.

There is another game with Dick and Dom in it where you have to find the antidote to the plague. In that one, you’re comparing and ordering fractions.

 

Dolphin Racing

Dolphin Racing from the BBC was one of my favourites. It’s still ok if you have the right Flash player but otherwise it won’t play.

Here are some more videos and activities from the BBC.

NCTM

Fraction Card Game

This is a good game which involves a bit of thinking rather than the speed of the arcade games below.

NRICH

For getting children to think more deeply but in an enjoyable way the NRICH site is fantastic!!

Consider bookmarking this page as there are 58 activities in the Fractions and related topics but you can narrow this down by Key Stage.

As a teacher this has got to be my favourite maths site and is well worth exploring.

Math Playground

In Math Playground the games are more like arcade games and so are popular with the children. This is an American site and has notes for teachers.

I haven’t figured out what happens in Fraction Forest games so let me know in the comments if you have or if you have found any instructions.

These tend to be more challenging, so are more useful for consolidation, speed tests and/or revision.

Education.com

Another American site with quite an arcade feel.

Education.com has 12 games – you need to scroll down to see all of them which isn’t always obvious.

How to teach multiplication tables

How to teach multiplication tables

At some point, every parent is probably considering how to teach multiplication tables.

As both a teacher and a tutor, this was something I gave a considerable amount of thought about it.

There are lots of methods – and you will want to try different methods with different children. I suggest you bookmark this page so you can come back to it (Control +D). Don’t keep pushing a method they hate and don’t try to move too fast, especially if they are under 7. You will, no doubt, come across parents who are delighted that their children know their tables at an early age, but children are all different. The important thing is not to put them off. It really is a case of slow and steady wins the race.

(I have quite a few links on this page, some of them go to Amazon and if you purchase through these links I will receive a small percentage – but it won’t affect the price you pay. I hope you don’t mind. It helps will the costs of running this site.)

I shall divide this into very rough age sections.

6-7 years olds

Here I would concentrate on playing games.

Try creating some cards with your child to use for matching games. They don’t need to be playing card size.

Let your child choose a theme – eg Star Wars, dolphins, whatever they like. Then take one of the tables and create a few cards to match.

e.g. 

 

I have done this on PowerPoint – which makes it really easy to get the pictures from the clipart section and you can reprint anytime you want.

You could start out by just printing two sets of up to 5 x 2 and match them, counting the dolphins, ordering them and telling stories – 2 dolphins were swimming in the sea when they saw two more, so they swam over to see them. Now there were four.

This age group also like to sing songs. You can find some on Youtube for free.

Start with 2s, 5s and 10s and then if/when ready also include 3s and 4s.

Also, don’t feel you have to be doing everything at once. Try picking a few cards, eg 2 x 6, 3 x 3, 4 x 2, 5 x 5, 3 x 10, and use those to put in order, match, and play snap or war.

7-9 year olds

This is when most of the learning of tables should take place so that your children are ready for more complex multiplication and division calculations.

Fortunately, there are lots of things you can do and resources available.

Carry on playing the games suggested above but introducing new sets of cards or buy some multiplication tables games cards.

Choose a game board you have at home and write some cards for it.  For instance, if you have a trivial pursuit board you could say if you land on a yellow you have to answer a 2 times question.  If you have a monopoly board you could replace the chance and community chest question with these cards – use the money to help you answer the questions.  The object of the game could be to collect the most properties, forget about houses and hotels when you start playing.

These cards could be useful to use – SmartyMaths Times Table Flash Cards Set of 144

Here we have an interesting game you can play with an ordinary pack of cards. It’s called Tables Combination.

Try the Maths trainer at https://www.mathsisfun.com/numbers/math-trainer-multiply.html .  Start with tables already know and do a minute at a time.  Change the question cut-off to 1 day otherwise children get really disheartened. Once they know tables well try introducing the 8-second cut-off.  Some children love this – others don’t!!

Multiplication.com http://www.multiplication.com/games/all-games has a great set of arcade type games. For a mixture of tables try Granny Prix, to pick individual tables or any mixture try Pirate Multiplication but those are just my favourites. Let your child choose their own.

 

10-15 year olds

At this age, if children haven’t learnt their tables they are often really fed up of people trying to make them learn them so it is really important to try and do things which engage their interest.

Multiplication.com http://www.multiplication.com/games/all-games is popular.

This Romany method really grabs some older children and adults who have struggled – and a useful step towards learning them. Younger children are much less likely to take to this in my experience.

Learn your times tables fast This video explains which are the hardest few sums to learn and makes it feel easier to accomplish the task by breaking it down.

 

Affirmations

Mindset is so important – try using these affirmations and others you make up.

Everday in every way – I am enjoying maths more.

I am an amazing mathematician!

Each day I learn something new.

I can do anything.

I and my family are good at maths.

I didn’t know I was good at maths but I am!

 

I hope this helps!

Try to help your child enjoy the process, and try to enjoy the time you are spending with your child.
