You could make your own 5 speckled frogs using whatever... socks, paper, egg boxes
and your own background - pond, log and grass by either drawing them, or using things you have around your house (be creative)
or you could print out and use the resource below.
This is a set of cards some with numbers and some with dots. You could use these to play a number of games...
This is a sheet with some 5 frames.
Make your own double sided counters using card and colouring one side in red and the other in yellow (or whichever 2 colours you want) and use them alongside the online videos.
Keep these as we will more than likely be using them again... and again... and again
To go alongside watching this episode of Numberblocks you could get 5 lego/ duplo blocks and investigate different ways of making different numbers.
e.g. get 3 blocks
Can they split it any other way? - e.g. 1 1 1
Repeat this idea with breaking other amounts into different parts.
