Year 1 Place Value Worksheets with Answers (PDF)

Children learn to compare pairs and sets of numbers from 0 up to 100. Building on the language of more than, less than, equal to, most, and least using pictorial representations and number lines, they evaluate which quantity is larger or smaller and record relationships using the <, >, and = signs.

A common error occurs when children focus on the value of the final digit instead of comparing the tens first. For example, a child might judge 38 to be larger than 51 simply because 8 is greater than 1. Children also frequently reverse the < and > symbols when recording their answers.

Practice tasks provide direct and varied ways to test these comparisons:

• Placing correct symbols in tasks like Insert the sign: <, > or = and Compute, then insert the sign.
• Arranging values through exercises such as Order five numbers or Order the numbers from greatest.
• Reasoning about missing amounts in tasks like Which group collected the least or How much is missing to one hundred.

In Year 1, children learn to count, read, and write numbers up to 100 in numerals and from 1 to 20 in words. Across the curriculum from Year 1 to Year 3, this learning progressively expands until children can read and write numbers up to 1000 in both digits and words. At this stage, the focus is on mastering the link between the spoken name of a number and its digit form.

A common mistake occurs when a number contains a zero in the middle. When asked to write a number like "one hundred and five", children often write the sounds literally as 1005, or skip the zero entirely and write 15 because they do not yet realise the zero must hold the tens place.

Practice tasks reinforce these patterns through direct questions. Children read numbers in words and write the number in digits, review given numbers to decide if the digits are written correctly, and tackle targeted problems such as fixing mistakes where a zero was missed in the middle.

In Year 1, children learn to count to and across 100, forwards and backwards, starting from zero, one, or any other number. Alongside counting in single steps, they practise skip-counting in equal steps of twos, fives, and tens, reading and writing these numbers in numerals.

A common difficulty arises when switching directions or crossing decade boundaries. When counting backwards in steps, children often slip into counting in ones or lose track of the interval—for instance, jumping backwards by five and saying 30, 25, 24 instead of continuing to 20. Reversing the sequence requires holding the step size in mind while moving in the opposite direction.

Worksheet activities reinforce these patterns through varied tasks. Children practice continuing sequences where they keep counting by the same step, choose the next number from options, or count backwards in equal steps. They also develop error-checking skills by finding and correcting the wrong number in a given sequence, or figuring out how many times they must count on to get there.

In Year 1, children learn to find one more and one less than any given number as part of counting up to 100. They build an understanding that moving one step forward gives the next number in sequence (the successor) and moving one step back gives the number immediately before it (the predecessor).

A common mistake happens when crossing a tens boundary, such as finding one less than 40 or one more than 29. Because children are often more confident counting forward than backward, they may mistakenly increase the number when asked for one less, answering 41 instead of 39.

Practice tasks prompt children to identify which number is 1 greater or which number is 1 smaller. Other activities challenge pupils to look at both neighbouring values at once, asking them to find the sum of the successor and the predecessor or decide whether a calculation involving both neighbours is true or false.

In Year 1, children learn to identify and represent quantities using structured pictorial representations. They work with visual sets, such as counters placed inside frames, systematically counting each item to find how many there are and recording the matching written numeral.

A common mistake is losing track during the count, which leads to either skipping an item or counting the same counter twice. Children may also arrive at the correct final count verbally but write down an incorrect numeral, particularly with two-digit numbers where the digits might be transposed.

Worksheet tasks present children with counters arranged inside frames. Children count the filled spaces within the grid and write down the corresponding number.
