Is the number of dinosaurs in set A greater than, less than, or equal to the number in set B.

We’re shown two pictures of dinosaurs, set A and set B. We have to compare the two sets. We have to decide if set A is equal to set B, if set A is greater than set B, or if set A is less than set B. Before we choose the missing symbol, we need to compare both sets of dinosaurs.

Let’s count the dinosaurs in set A. We could place a counter on each dinosaur so we can keep track. One, two, three, four, five, six, seven, eight, nine. There are nine dinosaurs in set A. Let’s count the dinosaurs in set B. One, two, three, four, five, six. Set B has six dinosaurs. Which set has the most? It’s set A. Nine is greater than six. So, the missing symbol is greater than. Set A is greater than set B.
