Step 2: Teach Lesson
Ask the student if they know/remember what the words greater than, less than, and equal to mean. Give the following examples to
check for understanding: (Write each problem and solution on the board).
● Is 50 greater than or less than 75?
● Is 92 less than or greater than 22?
● Is 453 less than, equal to or greater than 453?
● Is 679 less than, equal to, or greater than 758?
Point to the symbols on the board (the answers). Tell the student that the symbol for less than or greater than looks like an alligator
ready to eat the bigger number. Alligators love to eat the biggest thing available. When the numbers are equal the equal sign is used,
meaning the alligator does not want either number or is confused about which to eat.
Have a stack of index cards with three digit numbers ready for the student. Give the student at least 10 cards. Tell the student to lay
out a pair on their desk and place the correct alligator between them (see attached). Check the student before doing the next set. Tell
the student that they are going to try a few more on their own.
The last few problems will be displayed one by one on the board. Choose a random set of three digit numbers and write them on the
board. Have the student hold up the correct alligator to solve the problem. Repeat for as many numbers as necessary to make sure
the student understand.
