In this worksheet, children explore numbers up to 100,000. They are introduced to the ten-thousands column in a place value chart and begin to understand the multiples of 10,000. This can be reinforced using a number line to 100,000. Both place value counters and plain counters are used in place value charts, allowing for discussion about the values of the columns.

In this worksheet, children deal with larger numbers while consolidating their understanding of the place value columns. They partition numbers in the standard way (for example, into thousands, hundreds, tens and ones) as well as in more flexible ways (for example, 16,875 = 14,875 + 2,000 and 15,875 = 12,475 + 3,400). Watch for: Children may make mistakes with the order of the digits when partitioning/recombining numbers with many digits.

In this worksheet, children extend their knowledge to deal with larger numbers while consolidating their understanding of the place value columns that have been introduced this year. They partition numbers in the standard way (for example, into thousands, hundreds, tens and ones). Watch for: Children may make mistakes with the order of the digits when partitioning/recombining numbers with many digits. You can use these supporting sentences: The value of the first digit is _________. The value of the next digit is ___________. ________ is equal to _______ thousands, ________ tens and _____-ones.

Children build on their learning to round any number within 100,000 to the nearest 10, 100, 1,000 or 10,000. They should be confident with multiples of 10,000 and the process of rounding should also be familiar. Children need to realise that the midpoint of two multiples of 10,000 ends in 5,000, so they need to look at the digit in the thousands column to determine how to round the number. Be careful with the language of “round up” and “round down” in case children mistakenly change the wrong digits when rounding. The previous multiple of 10,000 is ____ The next multiple of 10,000 is ____ Ask, “Which multiples of 10,000 does the number lie between?” “Which place value column should you look at to round the number to the nearest 10, 100, 1,000, 10,000?” “What happens if a number lies exactly halfway between two multiples of 10,000?”

In this worksheet, children recap their learning and extend their understanding to dealing with 4-digit numbers and adding and subtracting multiples of 1,000. The focus is on mental rather than written strategies. It is important to explore the effect of either adding or subtracting a multiple of 1, 10, 100 or 1,000 by discussing which columns always, sometimes and never change. For example, when adding a multiple of 100, the ones and tens never change, the hundreds always change and the thousands sometimes change, depending on the need to make an exchange.

Add and subtract numbers with up to four digits using the formal written methods of columnar addition and subtraction where appropriate Solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and why

Add and subtract numbers mentally with increasingly large numbers. In this worksheet, children recap and build on their learning from previous years to mentally calculate sums and differences using partitioning. They use their knowledge of number bonds and place value to add and subtract multiples of powers of 10. If they know that 3 + 4 = 7, then 3 thousand + 4 thousand = 7 thousand and 3,000 + 4,000 = 7,000. Children need to be fluent in their knowledge of number bonds to support the mental strategies. How does knowing that 6 + 3 = 9 help you to work out 60,000 + 30,000? “How can the numbers be partitioned to help add/subtract them?” "Are any of the numbers multiples of powers of 10? " “How does this help you to add/subtract them?”

Building on from the previous worksheet, children add two 4-digit numbers with one exchange in any column. The numbers can be made using place value counters in a place value chart, alongside the formal written method. When discussing where to start an addition, it is important to use language such as begin from the “smallest value column” rather than the “ones column” to avoid any misconceptions when decimals are introduced later in the year. After each column is added, ask, “Do you have enough ones/ tens/hundreds to make an exchange?" This question will be an important one in this worksheet , as the children do not know which column will be the one where an exchange is needed. Extra reasoning activity sheet.

Children work out subtraction word problems and correct the mistake and explain the exchange and possible misconceptions.

In these worksheets, children subtract up to 4-digit numbers with more than one exchange, using the written method of column subtraction. They perform subtractions involving two separate exchanges (for example, from the thousands and from the tens) To support understanding, solve these subtractions alongside the concrete resources of base 10 and place value counters. With extra reasoning sheet. With answer sheets

Children use a place value chart and place value counters to answer the questions. They exchange the counters when needed. They then solve the calculations already written in the formal method.

Children compare fractions where the denominator or numerators are the same. The examples and bar models support them. They find the equivalent fractions by using bar models. Extra reasoning sheet attached.

In this higher ability worksheets, children subtract up to 4-digit numbers with more than one exchange, using the written method of column subtraction. With extra reasoning sheet with answer sheets They perform subtractions involving two separate exchanges (for example, from the thousands and from the tens) as well as those with two-part exchanges (for example, from the thousands down to the tens if there are no hundreds in the first number). Remember, when completing the written method, it is vital that children are careful with where they put the digits, especially those that have been exchanged. Two-part exchanges can be confusing for children if they are unsure what each digit represents or where to put it. Watch for not lining up the digits in the place value columns correctly. When exchanging a number, they may put the ones in the incorrect place. When exchanging over two columns, children may exchange directly from, for example, hundreds down to ones and miss out the exchange to tens. Some high-level questioning will challenge high achieving students. Does it matter which column you subtract first? How can you subtract two numbers if one of them has fewer digits than the other? If you cannot exchange from the tens/hundreds, what do you need to do? Which column can you exchange from?

Children compare fractions where the denominators are the same or where one denominator is a multiple of the other. They also compare fractions with the same numerator or by comparing it to one half. with answer sheets. Extra reasoning activity sheet

Model making, drawing and writing decimal numbers, showing that the decimal point is used to separate whole numbers from decimals. Children look at a variety of representations of tenths as decimals, up to the value of 1 whole. This leads to adding the tenths column to a place value chart for children to see how tenths fit with the rest of the number system and to understand the need for the decimal point. Children may forget to include the decimal point. If the number of tenths reaches 10, children may call this “zero point ten” and write 0.10 rather than exchanging for 1 one. Children may confuse the words “tens” and “tenths”. Questions to help with understaning the topic: If a whole is divided into 10 equal parts, what is the value of each part? How can you represent the decimal How are decimals like fractions? using a model? How can you convert between tenths as fractions and tenths as decimals? How is 1/10 like 0.1? How is it different?

Children look at a variety of representations of tenths as decimals, up to the value of 1 whole. This leads to adding the tenths column to a place value chart for children to see how tenths fit with the rest of the number system and to understand the need for the decimal point. Useful challenging questioning: How are decimals like fractions? using a model? How can you convert between tenths as fractions and tenths as decimals? How is 2/10 like 0.2? How is it different?

his is a PDF file. These worksheets display numbers with up to 2 decimal places. Using a hundred piece of base 10 as 1 whole, a ten piece as a tenth and a one piece as a hundredth shows children that they can exchange, for example, 10 tenths for 1 whole, or 10 hundredths for 1 tenth. A hundred square where each part represents 1 hundredth, or 0.01, can also help children to see the relationship between a hundredth, a tenth and a whole. Children make decimal numbers using place value counters in a place value chart and read and write the numbers, as well as working out the value of each digit in the number. They also explore partitioning decimal numbers in a variety of ways. When reading or writing a number, children may say “one point twenty-four” instead of “one point two four”. When there are hundredths but no tenths in a number, children may forget to include the zero placeholder in the tenths column. You can use these questions to support your child. How can you represent this number using a place value chart? What is the same and what is different about a tenth and a hundredth? What is the value of the digit

This is reasoning activity targeted at lower ability Year 4. The number line in this question is a visual resource to support the understanding of decimal numbers. Before children attempt this worksheet, they should encounter, practice writing and reading decimal numbers and the decimal point, model making, drawing and showing that the decimal point is used to separate whole numbers from decimals in the main worksheet displayed on the website. Children look at a variety of representations of tenths as decimals on the number line. This leads to representing the tenths in the bar models and finally in the place value charts. The place value chart shows how tenths fit with the rest of the number system and to understand the need for the decimal point. Watch for: Children may forget to include the decimal point. Children may confuse the words “tens” and “tenths”. You might ask them: "If a whole is split into 10 equal parts, then what is each part worth? "If a whole is split into 10 equal parts, then what are the three parts worth?

This is reasoning activity targeted at Year 5. Before children attempt this worksheet, they should attempt to order fractions in the main worksheet displayed on the website. Bar models, fraction walls and number lines will still be useful to help children to see the relative sizes of the fractions, especially when conversions are needed. Children should look at the set of fractions as a whole before deciding their approach, as comparing numerators could still be a better strategy for some sets of fractions.
