The post Negative numbers in Year 5 appeared first on URBrainy.

]]>We have just added a further set of worksheets on negative numbers for Year 5 children. Our previous sets concentrate on recognising and ordering negative numbers. This new set takes this on a further stage where numbers are added or subtracted from negative numbers’ including finding the difference between a negative number and a positive number.

]]>We live in a strange world where we teach children about millimetres, centimetres, metres and kilometres but then on road signs we measure distances in miles. If we were deliberately trying to confuse children then we could hardly do better!

This week we bring some consistency to measurement by looking at distances in kilometres to various tourist attractions such as castles, historic houses and towns in the Lake District. These routes also involve adding decimals.

]]>The post Dividing by 10, 100 and 1000 appeared first on URBrainy.

]]>New this week for Year 5 are some quick mental division tips. Dividing by ten can be done quickly and easily by moving each digit one place to the right. A decimal point may need to be put in if moving from ones to tenths. In a similar way, dividing by 100 can be done by moving each digit two places to the right and, of course, moving each digit three places to the right will result in dividing by 1000.

]]>The post Year 5 Addition of decimals appeared first on URBrainy.

]]>The key to adding decimal fractions is to ensure that the decimal point lines up so that the tenths are in line, as well as the ones, tens etc. Using squared paper is also a great help with keeping each column in line. This type of question is very popular in the KS2 SAT papers and we have imitated the kind of layout found in the tests.

]]>Appearances can be deceptive. Our latest Year 5 reasoning worksheets look incredibly simple – just one question on a page and plenty of graphics showing fun days out to the zoo, water park etc. In reality they require a great deal of work; for instance, to decide whether a 3 for 2 offer is better than a family ticket. With three new sets, these form part of a superb collection of reasoning worksheets.

]]>A million no longer seems a large number in the modern world. With footballers being sold for over £50 million and houses in London costing well over £1 million it might be expected that children have a good understanding of large numbers. Indeed, children are expected to deal with numbers up to and beyond a million by the end of Year 5. However, this may not always be as easy as it appears and we have just published a great set of tricky questions involving numbers around one million to help with this understanding. Here is an example:

The new £1 coin has a thickness of 2.8 mm. How tall would a pile of one million £1 coins be?

]]>The post Rounding large numbers appeared first on URBrainy.

]]>We have just added three more sets of worksheets on rounding large numbers, suitable for Year 5. The first two look at rounding numbers with 5 digits (including decimals) to the nearest 10 and 100. The third set looks at rounding the same 6-digit number to the nearest 100, 1 000 and 10 000. This is very similar to the style of question found on the SAT Papers in Year 6.

]]>The post Times Tables appeared first on URBrainy.

]]>Why learning times tables is important.

Knowing times tables is very important for children for many reasons. Perhaps the most obvious is that it saves time when calculating.

If a child has to count up in fives and count on fingers to know how many lots have been counted (i.e. 5, 10, 15, 20, 25, 30) it is going to take them a whole lot longer than knowing the answer ‘off by heart’. Knowing times tables up to at least 10 times 10 is an incredibly powerful tool and really does make maths easier.

Just as important is that the knowledge of times tables is needed to work out any written multiplication or division, whether the long or short method is used. Divide 39 by 7 for example. If we know that 5 times 7 is 35 then it is easy to see that 39 divided by 7 is 5 remainder 4. If we don’t know that 5 x 7 is 35 then the problem gets a whole lot harder. Not knowing these facts is a major reason why many children and indeed adults think that they are no good at maths and why division is one of the main problem areas in teaching maths.

The introduction to algebra also needs a good knowledge of times tables.

C = 6. What is 7C + 3? Easy if you know that 6 x 7 is 42. Just add another 3 to make 45.

What can I do to help?

Times tables will be taught at school, but every child works at a different rate. Some find learning facts by rote very easy, others really struggle. But there is a very limited time in school and much of the real work in learning tables will probably be done at home. Good old Mum and Dad!

How can they be learned? There are many different ways. Some believe that singing them really helps, others recite them, almost like a poem, whilst many children like to time themselves to see how quickly a table can be completed. Another option is a quick fire computer game and there is no reason why our maths games cannot be used. (You do need the Flash Player although we are hoping to bring out some new games in the near future which will not use the Flash Player.) All seem to have one thing in common – repetition. Even now in some classrooms the whole class recite a table; that was the way I first learnt them many, many years ago!

So what is the best thing to do in the short time available? Well, a great start will be to browse through the extensive collection of highly targeted worksheets that we have on the times tables. You will find each table written out in words, plenty of practice on individual tables as well as further work on mixed tables and even plenty of fun activities, all designed to help your child learn the times tables. All these pages can be found in the multiplication category of the year groups that the National Curriculum state that they should be learnt in:

Year 2: 2x, 5x and 10x tables

Year 3: 3x, 4x and 8x tables

Year 4: 6x, 7x, 9x, 11x and 12x tables.

But they can also be found as a complete collection in our category:

]]>The post Year 5 weekly programme appeared first on URBrainy.

]]>The final six weeks of the year 5 weekly programme are now available and there is plenty of tricky work for these last weeks.

Week 31 takes a look at large numbers, percentages, money problems, graphs and angle, as well as formal written methods of multiplication and subtraction.

Week 32 concentrates on place value, fractions and decimals as well as consolidating work on angle and time. Prime number questions are also included.

Week 33 has a wide range of topics including subtracting fractions, finding the mean and mode, the area of shapes and Roman numerals.

Week 34 is very much about number, with pages on mentally adding decimals, solving subtraction puzzles, practice for 4 rules and percentages. As a contrast there is also work on interpreting line graphs.

Week 35 is bringing us close to the end of term and targets some of the harder maths to be covered in year 5, including percentages, area, fractions and problem solving.

Finally, Week 36 finishes the year with pages on percentages, timetables, multistep word problems, fractions and a jolly number investigation.

Of course, all these resources and many, many more can be found within the Year 5 category and we recommend going to these for further practice if any problems arise.

Please note we will shortly be taking down all the weekly programmes apart from this last half term so that we can review them and update if necessary for the next school year.

]]>The post Reasoning worksheets for Year 5 appeared first on URBrainy.

]]>Many of our resources in all categories involve mathematical reasoning, but we also have a special area, called Reasoning/Problem Solving for each year group which really concentrates on this important aspect of Mathematics.

We have just published four new sets of resources for Year 5 Reasoning on:

• Ordering decimals

One way to put decimals in order of size is to set up a table with the decimal point in the same place for each number; this makes it much easier to compare decimals to see which is the larger (e.g. 0.65, 5.6, 0.605 etc).

• Finding half way between two decimals

There are several ways of finding a number half way between two others and this applies equally well to decimals.

One way is to add the two numbers and then divide the answer by 2.

Another way is to find the difference by subtracting the smaller number from the larger number. Halve the difference and add this to the smaller number.

Which method to use would depend on the numbers involved and it is a good idea to ask children why they have chosen a particular method.

• Word problems with decimals

Here is a typical word problem involving decimals:

Liz chooses a number less than 20. She divides it by 2 and then adds 10. She then divides this result by 5. Her answer is 3.7. What was the number she started with?

Questions like this depend on knowing that addition is the opposite of subtraction and multiplication is the opposite of division. The reasoning comes in as the calculation is worked through step by step; if her answer is 3.7 and she had divided by 5 then multiplying by 5 will complete the first step…. and so on.

1. Start at the end with the final answer which was 3.7.

Multiply 3.7 by 5 (because Liz divided by 5). 3.7 x 5 = 18.5

2. Take away 10 from 18.5 (because Liz added 10) 18.5 – 10 = 8.5

3. Multiply 8.5 by 2 (because Liz divided her number by 2) 8.5 x 2 = 17

4. The number Liz started with was 17.

5. Check by dividing 17 by 2, adding 10 and dividing by 5

• Ordering fractions

Ordering fractions with different denominators needs a good understanding of equivalent fractions and the questions are quite hard (e.g. order five ninths, two sixths, two thirds and one twelfth). It is important to change the fractions so that the denominators are all the same. If these prove difficult it would be well worth looking at our Fractions category to get further practice.
