Not only maths but some fascinating population facts thrown in as well. Why not try to find these South American countries whilst rounding their populations to the nearest million?

When rounding to the nearest whole million it is the hundred thousand digit which is important.

2 345 456 is 2 000 000 (two million) to the nearest million

2 987 654 is 3 000 000 (three million) to the nearest million.

If the hundred thousand digit is 5 or more round up. Otherwise round down.

Now we are getting to the real nitty-gritty of reading and writing large numbers up to millions. These are not easy: there are millions of adults in the UK who can not write

12 120 012 in words!

The first of these free maths worksheets looks at the abacus to help with reading 4-digit numbers. Notice that the question asks for the numbers to be written in figures and in words. Figures should be easy – words might be harder. Continue reading “Free Y4 maths worksheets: Partition into ThHTU”

Two more free maths worksheets on counting along a number track, filling the missing numbers. Some of these questionscross the hundreds boundary which is usually where any problems might develop. Encourage your children to say the numbers out loud as they write the numbers down.

By year 2 children should be more able to count on from larger numbers, up to 100. There is no help with these maths pages but some children might need a number line or number square.

When counting on make sure that they do not include the starting number. For example: count on 5 from 32. Continue reading “Free Y2 maths worksheets: Count on”

To get back to our counting pages for the early years here are two free maths worksheets to help with counting up to 10 . They are really examples of the kinds of pages that you can create or your children could make similar themselves. They go very well with the counting games activities – don’t forget to use these in conjunction with the worksheets.

Now, we all know that the probability of tossing a coin and getting a head is the same as tossing a coin and getting a tail. But this does not mean that if we get a head on the first toss we will get a tail on the second. The chances are equal on each toss of the coin, independent of what happened on the toss before. It is quite possible to have a run of heads up to 4 or 5 or more in a row.

The first worksheet explores this idea. It is important to get your children to write down their predictions before they start, carry out the coin tossing and then to compare the prediction to the results. Ask questions such as “If we carried out the coin tossing again would we get the same results?”

The second worksheet explore the same idea, but this time with even or odd numbers on a die. There predictions may well be biased as a result of what they think has happened to them when playing dice games: “I never get a six….”

Again it is unlikely (but by no means impossible) that after 50 throws of a die that 25 odd and 25 even numbers are actually thrown, but as a prediction this would be excellent.

Probably one of the least understood of maths concepts, especially with young children.

Children should be able to say whether events are impossible , unlikely , likely or certain.

They should also be able to say which events have an even chance of happening (such as tossing a coin and getting a head), but they should be careful not to say that if there are two possibilities, they are equally likely. For example, there are two possibilities – I might buy a new BMW today or I might not. Unfortunately, these two events are not equally likely. Another example of this is I choose a number between 1 and 5. Is the number I choose a prime number? As there are three prime numbers between 1 and 5 (2, 3 and 5) and two numbers that are not, there is not an even chance that I will choose a prime number.

Sometimes further investigations have to be carried out before a probability question can be answered. Take the possibility of a factor of 16 being even. The only way of doing this is to first find all the factors of 16, group them into even or odd and then work out the probability.

Now we are coming on to more familiar territory for most people when we think of graphs: the bar chart or bar graph. Here the vertical bars represent the number of people going out on a boat. Each bar is completely separate from the others.

It is important that children get used to naming the horizontal and vertical axes and that these axes should always be named.

The hardest part of interpreting this bar chart involves the number of people shown on the vertical axis. Continue reading “Free Y4 maths worksheets: Bar charts”
