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
