A two-part Year 4 rounding sheet over three pages, with the answer key on page 3. Part 1 asks which whole numbers round to 40, 600, 3,000 and 70, with a number line from 30 to 50 above the questions. Part 2 gives four number puzzles that mix rounding with digit clues, such as a 3-digit number that rounds to 400 and to 430 and whose digits add up to 14. It follows England National Curriculum Year 4 number and place value.
Number - number and place value
“round any number to the nearest 10, 100 or 1000”
Questions 1 to 6 ask for the numbers that round to 40, 600, 3,000 and 70, and every puzzle on page 2 starts with a rounding clue.
Number - number and place value
“solve number and practical problems that involve all of the above and with increasingly large positive numbers”
The four puzzles on page 2 combine rounding with even numbers and digit totals.
Six questions. Pupils list every whole number that rounds to 40 to the nearest 10, find the smallest and largest numbers that round to 600 and to 3,000, and count the numbers that round to 70.
A number line marked 30, 35, 40, 45 and 50 sits above question 1 as a picture of the tens.
Four boxes, each a mystery number with a rounding clue and a digit clue, such as a 2-digit even number that rounds to 50 and has digits adding up to 12.
All ten answers with a short reason, for example that the numbers from 65 to 74 round to 70.
Boundary lesson
Use question 1 to show why 35 rounds up. Ask pupils to say which number sits halfway and which way it goes.
Puzzle pairs
In puzzle 3 the tens and ones digits are given, so the rounding clue decides the hundreds digit. Ask pairs why it has to be 1.
Early finishers
Pupils who finish can write a puzzle of their own with exactly one answer and swap it with a partner to check.
