We use the number zero to mean there are no items. There are two ladybugs. There are zero butterflies. What number is missing? There are what ants?

We’re shown three different pictures and three different sentences. In the first picture, there are two ladybugs on the leaf. This is what the sentence tells us. There are two ladybugs. The second picture shows us that there are no butterflies on the leaf. The second sentence tells us that there are zero butterflies. In the third sentence, the number is missing. We need to count the ants and write the missing number to complete the sentence: one, two, three. There are three ants. The missing number is number three.

What number is missing? We’re shown a picture of a leaf. There are what caterpillars.
