Checking by Estimating: Free Printable Worksheet for Year 5

Checking by Estimating is a free printable worksheet for Year 5 (ages 9 to 10), in Key Stage 2. Spot the wrong answers. It comes from the Mini Minds Hub, a growing library of free printables from Jaques of London, the British games and toy company that has been making games for families since 1795.

It is two A4 pages. Page 1 is the activity for children. Page 2 is for the grown-up: it has notes on how to use the sheet, help for children who find it hard, a stretch idea, and the answers. Print it at home or in the classroom. Black and white printing works well.

What is on the sheet

This worksheet includes numbered questions with space to answer.

A look at what children will meet:

  • 49 + 52 = 201
  • 398 + 205 = 603
  • 81 - 39 = 62
  • 7 × 49 = 343
  • 603 - 198 = 805
  • 19 × 5 = 195
  • 312 + 689 = 1,001
  • 52 × 4 = 208

Who this is for

Year 5 (ages 9 to 10) in Key Stage 2.

Key Stage 2 covers Years 3 to 6, ages 7 to 11. Children are widening what they know and getting better at explaining their thinking, so activities that ask them to reason, not only recall, are especially useful. Use it at home, in class, on a rainy afternoon or at a family gathering.

A screen-free maths activity for Year 5

Children spend a lot of time on screens. This is a screen-free maths activity that needs only paper and a pencil. It works as quiet time after school, a rainy day activity, a holiday boredom buster or a calm moment before bed. Screen-free learning gives eyes a rest and gets children talking, thinking and writing by hand.

Free maths resources for teachers

Teachers can use this worksheet as a starter, a plenary, an early finisher task, a supply teacher resource, a homework task or a table activity. It needs no preparation beyond printing. The learning focus and skills are listed above so you can match it to your planning, and page 2 gives support and stretch ideas for mixed ability groups.

Maths ideas for parents at home

You do not need to be a teacher to use this. Read the sheet through, sit with your child for the first go and let them lead. Short bursts of ten to fifteen minutes work better than long sessions. If you are looking for free maths worksheets for Year 5, or simple home learning for the weekend or school holidays, this is a good place to start.

Home education and tutoring

Home educators and tutors can print this as part of a wider maths plan. It pairs well with books, outdoor play and everyday talk. Because the sheet is free and printable, you can use it again for brothers and sisters or for revision a few weeks later.

Why it helps children learn

Hands-on, paper based activities slow learning down in a good way. Children read carefully, think before they answer and see their own progress on the page. Games and challenges add a reason to keep going. That mix of play and practice is why printable activities like this are popular with parents, teachers and home educators.
