Really good Early Years Number activity which even the boys love.

Match sets by matching the numbered key to the lock with the correct number of dots on it. GREAT for fine motor skills and very motivational! Or by padlock in the numicon tile.

Number formation display

Number formation display I think this is fabulous for engaging the boys. I would probably introduce one number at a time and slowly build it up.
