Give the plus sign something to describe
Look at each group before reading the calculation. The sign + describes joining the quantities. Counting the objects together helps connect the written symbols to a visible action, rather than treating the equation as a shape to memorise.
Return to the objects whenever needed
A child can recognise numerals and still need help with the meaning of addition. Use small real groups first, then come back to the screen. Mistakes receive a gentle invitation to try again; there is no timed score to chase.
