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 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

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

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 use their knowledge of comparing fractions and order a set of three or more fractions. If equivalent fractions are needed, then one denominator will be a multiple of the other(s) so that conversions will not be complicated. C Bar models, fraction walls and number lines could be used to help children to see the relative sizes of the fractions, especially when conversions are needed. Children can consider the position of a fraction relative to 0, 1/2 or 1 whole. With extra reasoning sheet. You can support your child with set of questions: If a set of fractions all have the same denominator, how can you tell which is greatest? If a set of fractions all have the same numerator, how can you tell which is greatest? How can you use equivalent fractions to help? What are all the denominators/numerators multiples of? How can this help you find equivalent fractions? Which of the fractions are greater than 1/2? At first, children may need support to decide the best strategy when there are more than two fractions. Children may not look at both parts of the fractions when making their decisions about the order. You might use these support sentences: When fractions have the same denominator, one with the_____ numerator is the greatest fraction. When fractions have the same numerator, the one with the ______ denominator is the greatest fraction.

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?

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?

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.

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 challenge your child. Can you partition the decimal number different ways? How many tens are there in 100? How many ones are there in 10/100? How many 0.1s are there in 1? How many 0.01s are there in 0.1?

In this reasoning worksheet, children explore the tenths and the hundredths columns in a place value chart, extending their previous learning to include numbers greater than 1. They should know that 1 comes after 0.9, and when counting backwards that 0.9 comes after 1. Links can be made to the equivalence of 10 ones and 1 ten to support understanding. Challenge your children with these questions: What is the decimal point? How many wholes/tenths/hundredths are in this number?

In this higher ability worksheet, children use the column method for addition and learn to apply this method to numbers with more than four digits. Ask, “Does it matter if the numbers have different numbers of digits?” “How do you know which digits to “line up” in the calculation?” “How do you know if the calculation is an addition?”

This is reasoning activity where children are using the knowledge of times table and dividing 1 digit number by 10. Ask, “When dividing a number by 10, how many equal parts is the number split into?” They recognise that when using a place value chart, they move all of the digits one place to the right when dividing by 10. Watch for: Children may divide by 10 and put the decimal point in front of the number. Children may move the digits in the wrong direction.

In this worksheet, children find the effect of dividing a 1-digit number by 10, identifying the value of the digits in the answer as tenths. They divide a 1-digit number by 10, resulting in a decimal number with 1 decimal place. The number is shared into 10 equal parts. This can be shown by exchanging each place value counter worth 1 for ten 0.1 counters. They recognise that when using a place value chart, they move all of the digits one place to the right when dividing by 10. Ask, “What number is represented on the place value chart?” " When dividing a number by 10, how many equal parts is the number split into?" “How many tenths are there in 1 whole/2 wholes/3 wholes?”

This is reasoning activity with missing numbers. Ask, “Will you need to make an exchange?” “Which columns will be affected if you need an exchange?” "How do you know? “Does it matter if the numbers have different numbers of digits?” “How do you know if the calculation is an addition?”

In this higher ability worksheet, children practise their rounding skills to estimate the answer before working out the calculation, and then use it as a sense-check for their solution.

In this worksheet, children subtract whole numbers with more than four digits, including using formal written methods (columnar subtraction). Place value chart and place value counters can be used for support. It is useful when performing calculations that require an exchange. Squared paper and labelled columns will support children in placing the digits in the correct columns. Children experience both questions and answers where zero appears in columns as a placeholder.

This is support mat featuring Decimals in Year 4. Significant help for parents, children and teachers. Great for homework and homeschooling. It can be used as a visual display in the classroom or on the desk.

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?” Extra reasoning sheet attached.
