Do you have building blocks at home, not necessary to have wooden blocks you can use even foam blocks or even Lego blocks.
So whatever you are using create patterns accordingly. What I did? I cut an A4 sheet into equal 4 equal pieces, the number of A4 sheet depends on the number of pieces you want. First I built a simple structure using the blocks, then using that as a reference I drew the structure on the piece of the paper (to use as cards), continue doing the same by building different structures and making different patterns.
According to the blocks you have and age of the child, make the pattern cards. Ask you child to replicate the patterns using the block. Improves the observation of the child and motor skills.
