This set work perfectly for kids who struggle with addition.
All digits are visualised with shells or pebbles.
There is also space for self assessment or peer assessment.
All images used are arranged and taken by me :)
Apart from cover sheet and clue sheet there are 5 shells sheets and 5 pebbles sheets with raising difficulty level.
