Use this primary lesson to introduce greater than less than or equal to. Using animals, and an alligator to represent the >,<,= symbols, the students count the animals on each side and determines which side the alligator will want to eat. They "erase" the water between to check to see if they were correct and uncover the alligator.
If the number is the same, the alligator gets confused and goes in the water.
It also provides slides for the students to draw the symbols when comparing base-10 blocks or tally marks.
