⬛ Area and Perimeter for Kids: Free Games and Worksheets

Area and perimeter for kids becomes easy when children can see it on a grid. In this free module, kids count squares to find area, trace the edges of a shape to find perimeter, and then discover the shortcut rule: length x width. There are four activities, from simple rectangles to L-shapes with two parts. Every activity can be played online on a phone, tablet or computer, and the same page can be printed as a worksheet for classwork or homework practice.

What these area and perimeter activities are

This page brings together four hands-on maths activities that teach two closely linked ideas: area (the space inside a flat shape) and perimeter (the distance all the way around its edge). Children start with squared grids, where one square equals one unit, so they can literally count what they see instead of memorising a formula.

Area: Count the Squares - count the shaded squares inside a shape and write the total in square units.
Perimeter of Rectangles on a Grid - move along each side, add the lengths and find the distance around.
Area of Rectangles: Length x Width - connect counting with multiplying, and see why the shortcut works.
Area and Perimeter of L-Shapes - split a compound shape into two rectangles, solve each part and combine the answers.

All four activities are free, with no sign-up needed to start playing.

Skills children build

Area and perimeter sit right where arithmetic meets geometry, so these activities quietly strengthen several skills at once.

Careful counting - counting squares in rows and columns without skipping or repeating.
Multiplication sense - seeing 4 rows of 6 squares as 4 x 6 makes times tables meaningful.
Units - learning to say "24 square units" for area and "20 units" for perimeter.
Problem solving - breaking an L-shape into friendly rectangles.
Attention to language - noticing whether a question asks for inside space or edge distance.

Children who are still building number confidence often benefit from a short warm-up with addition with pictures before they tackle a perimeter page.

How to play online and how to print

Open any activity and it loads straight in the browser on a phone, tablet, laptop or classroom smartboard. Kids tap or click to choose an answer and get instant feedback, so they can self-correct without waiting for an adult. Nothing needs to be installed.

Prefer paper? Use the print option on the activity to get a clean black-and-white worksheet that saves ink. Printed grids are excellent because children can shade squares with a pencil, mark each side as they count, and leave a visible record of their thinking. Many teachers play one round on screen as a whole-class demonstration, then hand out the printable version for independent work.

Ideas by age

Ages 4-5 (preschool and kindergarten): formal area is not expected yet, but the groundwork is. Let little ones trace around the outside of a rectangle with a finger and count the squares inside like stepping stones. Pair this with shapes for kids so they can name squares, rectangles and triangles confidently.

Ages 6-8: this is the sweet spot for counting squares. Ask for the area first, then the perimeter of the same shape, so the difference becomes obvious. Keep numbers small and let children say the unit out loud every time.

Ages 9-12: move to length x width, missing-side problems ("the area is 36 and the width is 4, what is the length?") and L-shapes. Challenge older children to draw two different rectangles with the same area but different perimeters.

Tips for parents and teachers

Use real rooms and objects. Measure a book cover, a table top or a floor tile. Perimeter is the ribbon around a gift; area is the paper that covers it.
Say the unit every time. Square units for area, plain units for perimeter - this prevents the most common mix-up.
Mark as you go. Teach children to tick each square counted and each side measured.
Keep sessions short. Ten focused minutes beats a long, tiring sheet.
Celebrate the method, not just the answer. Ask "how did you work that out?" and let the child explain.
Build number confidence alongside. Quick practice with bigger or smaller comparisons helps children sense whether their answer is reasonable.

Why grid-based practice works so well

Formulas learnt without pictures are easily forgotten or swapped around. When a child has counted 5 rows of 3 squares many times, the rule length x width stops being a rule to remember and becomes something obvious. The same is true of perimeter: after walking around enough grids, children naturally start adding opposite sides and doubling. These four free activities are designed to be repeated, so keep coming back - a few minutes a week builds lasting understanding and makes later topics like volume and surface area much friendlier.

Frequently asked questions

What is the difference between area and perimeter?

Perimeter is the distance all the way around the edge of a shape, measured in units. Area is the amount of space inside the shape, measured in square units. A simple way to remember: perimeter is the fence, area is the grass inside it.

At what age should children learn area and perimeter?

Most children meet perimeter and area by counting squares around ages 6 to 8, then use length x width around ages 8 to 10. Younger children can still enjoy the grids by colouring squares and tracing edges, which builds useful early measurement sense.

Are these area and perimeter activities really free?

Yes. Every activity on this page is completely free to play online and free to print as a worksheet. There is no sign-up, no payment and no limit on how many times your child can practise at home or in class.

Can I print these as worksheets?

Yes. Each activity has a print option that produces a clean, ink-friendly black-and-white worksheet with grids. Printed pages are great for homework, revision folders and classroom stations, and children can shade squares with a pencil as they count.

How do children find the area of an L-shape?

Split the L-shape into two rectangles with a straight line, find the area of each rectangle using length x width, then add the two answers together. For perimeter, simply add the lengths of all the outside edges, including the short ones.

Do children need to know times tables first?

Not for the counting activities, which only need careful counting and addition. For the length x width activity, knowing tables up to 10 makes work faster, but children can still count squares or add repeated rows while their tables improve.

Which devices do these activities work on?

They work in any modern browser on phones, tablets, laptops, desktops and classroom smartboards. Nothing needs to be downloaded or installed. Larger screens are helpful for L-shapes, as children can see the whole grid without scrolling.

What should my child practise next?

Once area and perimeter feel comfortable, strengthen the supporting skills. Try shapes for naming and properties, number order for sequencing confidence, and multiplication practice to make the length x width rule quick and automatic.
