This Blackboard wooden Ruler Height Chart has a Blackboard paint strip down the centre so that you can write all your families heights on in chalk pen. Not only is it a great alternative to our plain Ruler in the home but it’s a great addition to a school classroom. Start the school year by marking all the children’s heights on the Ruler and see how they grow. Then at the end of the year wipe your Ruler clean ready to start again with your next years class.
