Choosing and using appropriate standard units

To estimate and measure length/height, mass (kg/g); temperature (°C) and capacity (litres/ml) to the nearest appropriate unit, is the most important part of this goal. Make sure you use desired vocabulary and help your kids to explore the world. Take them to a Science Museum or any Laboratory for kids. There is also lots of things you can do at home.

Capacity (litres/millilitres)

Make it

Make your own 1 litre measuring jug

Tell your child that 1 litre = 1000ml or, if you have a jug that has marking like mine, you can investigate how many ml are in one litre. Have a look around your kitchen first and see what can you find.
Have a think together how to make 1 litre jug? We had a syringe, small container and and old juice bottle.


Use medicine syringe 5 ml (you probably have more than one of those, right?)to make the first small 10ml container. Use it to make 100ml - count in 10s. Finally using 100ml jug/bottle make 1 litre container. Don't forget to count in 100s! We used abacus to help us keep a track of counting.

Investigate the world


How much water do you think this container can hold? Any answer in litres will be great!


Fun in the lab!

Test tubes

This set is amazing to start your little lab. I don't recommend to buy coloured test tubes, because it is better to use food colouring in the water. Your child will have way more fun mixing liquids and colours when they can see them well. I have few coloured (that I thought are very cute) but non of my kids like them...

Mesuring cylinders

I like this set of 4, because it has the numbers written in blue, so it is easier to read them and... it is sooooo cheap!!!

Water colouring

If you are afraid that the food colouring will stain your child's fingers, use water colouring tablets. They are design for bath time so will not colour your child.

Mass (kg/g)

Make it

Go on a trip


If you live in London check the Science Museum, there is amazing Wonder Lab. The above picture has been taken in We The Curious in Bristol. Check what is avaible around you, and please share it with me!

Experiment at home

mass kg

The goal is to know the difference between grams and kilograms.

How many grams are in a kilo? How heavy is one gram? Use a kitchen scale to weigh pasta. How much pasta is 1 gram vs 1 kilogram Let your child discover that kilo means 1000, so 1 kilogram is 1000grams.

Use your knowledge in everyday situations


The challenge


Using balancing scale order 3 objects from lightest to heaviest.

Buy it

Balancing scale

Very often I use this balancing scale because it also holds liquids and has lids. But the set above is a real winner! It comes with compare bears!

Length/height in any direction (m/cm)

Make it

Make your own measuring stick/ meter stick

Explain to your child that 1 meter equals 100cm. and how to get to 100? 10+10+10+10+10+10+10+10+10+10 =100 We use a ruller to measue 10cm parts and marked them with a felt pen. After that my son painted each 10cm different colour. I'm not sure if painting was a good idea... Maybe felt pens would be better... Oh, and we found that bamboo stick in our garden. Eric loves this stick, he measured nearly everything in our house and that includes his baby brother :)

Build towers


Measuring your own build is great allows your child to be more specific when they describe how tall is it.

The challenge

Are you taller lying down or standing up?

Give your child something to measure the world around them

Keep a measuring tape in your bag. Take it out when your are out for a walk and feed your child curiosity by checking how big/or long are things around us.

Give your child something to measure the world around them - 'be careful' option

It is so much fun to use this tape, but mind your fingers!

Temperature (°C)

Make it

Checking outside temperature


Encourage your child to record the temperature outside. Ask alexa what’s the weather like today? Say a fun fact: In 0°C water freezes - take some lovely pics of frost In 100°C water boils - you wouldn't like to be in there!

What is your preferable outside temperature?

Measure your own temperature

temperature kids

Allow your child to measure their body temperature. Use one of your ear thermometers for safer option.

Fun facts: 36.6°C is your normal body temperature.

How high your temperature has to be to skip school and stay in bed?
