Addition Examples:
Result Unknown Two bunnies sat on the grass. Three more bunnies hopped there. How many bunnies are on the grass now? 2 + 3 = ?
Change Unknown Two bunnies were sitting on the grass. Some more bunnies hopped there. Then there were five bunnies. How many bunnies hopped over to the first? 2 + ? = 5
Start Unknown Some bunnies were sitting on the grass. Three more bunnies hopped there. Then there were five bunnies. How many bunnies were on the grass before? ? + 3 = 5
Subtraction Examples:
Result Unknown Five apples were on the table. I ate two apples. How many apples are on the table now? 5 – 2 = ?
Change Unknown Five apples were on the table. I ate some apples. Then there were three apples. How many apples did I eat? 5 – ? = 3
Start Unknown Some apples were on the table. I ate two apples. Then there were three apples. How many apples were on the table before? ? – 2 = 3
