In school numeracy is often taught using practical materials, in particular numicon and ten frames.
Ten frames
A ten frame is a rectangle split into 2 rows and 5 columns.
It is used to show numbers that are less than or equal to 10.
Placing objects on the frames helps children to visualise different ways to represent numbers.
You could download and print the ten frame sheet below from Twinkl

or
make your own.
An empty egg box can be a great 10 frame.
It is a great way to help children organise amounts to count.
Numicon
The links below open free resources from the numicon website that I find helpful, although I do recognise that you might not have access to a printer.

How to make your own numicon – a bit fiddly but a great measuring activity for older children.
