Make the biggest nowball possible whilst creating a maze or interesting pattern of grass to follow afterwards.

Does the size of the snowball relate to the length of the path created? How could you work this out?

As well as grass tracks left by rolled up snowballs, animals and birds leave trails and tracks too. Find some tracks and follow them. Do this quietly to avoid frightening any thing or anyone.

Some times I meet people who are surprised when I suggest that all aspects of maths can be taught outdoors. After all, money and playing in a natural space do not obviously go hand-in-hand the way that perhaps it would with a role play area about a train station.

Honesty or Lunaria annua is one of my favourite plants because it's beautiful seed heads are one of winter's wonders. As a child I adored the translucent paper thin head and the seeds tucked in between the thin flat pods. It is the seeds that are the "money". In the right garden, a child could become very rich. I rather like the potential for the seeds to become fairy money or nature's money.

On a cold and frosty day, it is perfect weather for a winter walk. Often the air is still, the sky bright and the colours of the earth simply glow. Take a magnifying glass or fresnel lens and just enjoy looking at the frosty "jewels" decorating the plants.

For older children, working out how this hoarfrost was created is an interesting challenge. Essentially it's frozen water that's taken on a crystal form. Water vapour in the atmosphere has frozen onto the colder plant surface.

Altogether quite remarkable.

Make a snowman without a head. For younger children this can be done simply by trying to make the largest snowball possible. When it's too big too move, it's probably ready...

Then take turns to stand behind the snowman as if your head belongs to it. Have a range of props such as wigs, hats, scarves and sunglasses to wear. Take photos of each other doing different snow man poses.

Playing in Snow is "snow" much fun!

Most children enjoy making snow angels by lying on the ground and moving their head, arms and legs.

You can take this one step further by putting out a variety of seeds, nuts and other bird food into the shape - decorating the angel.

Then find a quiet spot and watch and wait for the birds to come visiting.
