Have you tried using Popits as a maths manipulative? 

Cat says, 
‘A few weeks ago one of my pupils showed me the ‘Popit’ she got for her birthday!  I was soon talking to her about the ways we could use it for maths! A little bit of investigation after her lesson and I found a 10×10 Popit! I had it in my hands before you could say ‘Popit’ and I’m super excited about using Popit’s in my maths lessons!
My first ideas for using Popits for maths are in the video below- I am sure you can think of many more!  I can’t wait to try them out! 
What a lot of multi-sensory fun we can have with these!’
