I may not be able to come up with the printable but I do love things that can be easily adapted to give such a variety of activities. First here is the link to the printable: http://picklebums.com/2013/02/26/free-printable-hexi-cards/
Activity 1: Baking Tray/Cookie Tray/Magnetic Board Patterns.
For this activity I printed out the hexi card printable on paper, laminated it for durability, cut them out and glued magnetic tape to the back. With this Little Boy Blue will be able to make what ever pattern he wishes in what ever way he wishes on the baking tray or his magnetic board. For the photo I matched colours together for this star/ flower shape but it is really ideal for free play and exploration.
Activity 2: Memory Match Up Game or Snap.
Little Boy Blue may be a little too young at the moment for this one but his big brothers Book Worm & Bug Boy will love it. For this activity I printed, laminated and cut out enough of the hexi card printable to give me six matching pairs of colourful hexagons. Like all other memory match up games the cards will be tuned face (picture) down and the boys will take turns to turn over two cards and if they match (same colour combination) then they get to keep the pair, the winner is the player with the most pairs at the end. Another game could be snap, just print out more cards. This could also be a busy bag activity.
Activity 3: Colour Peg Match Busy Bag.
Find one hexi card with a least one of each of the different colours, colour wooden clip on pegs to correspond (I just used felt tips to colour the pegs), pop the lot into a ziplock bag and you have a busy bag made.
Activity 4: Hexi Card Match Up Board & Pieces.
Here I printed out 2 hexi card sheets, one on card the other on paper, laminated them both but only cut out the laminated paper one. This is more for individual work and could be made into a file folder game by sticking the laminated card play board into a file folder and popping the play pieces in a pouch. The instructions are very simple: match the play pieces on to the corresponding coloured hexagon on the board.
Activity 5: Colour Pompom Match Busy Bag.
Again you print, laminate and cut out the hexi card printable then find some pompoms that match the colours on the cards. I used quiet small pompom but depending on fine motor skill you could use larger pompoms and also to add a twist pop in a set of tweezers or a clip peg for the child to manipulate the pompoms on to the correct colour on the cards, pop it in a ziplock bag and you have another busy bag.
Hope you give these a try and come back to let us know how you get on.
