Kindergarteners have recently been learning how to compare numbers. In our classroom, we use the “alligator method” to help teach this concept. It’s a fun and visual way for students to understand the idea of “more” and “less.” For this method, we visualize an alligator with its mouth open, eager to eat the larger number. The alligator’s mouth always faces the larger number, reinforcing the idea that “greater than” is represented by the open side of the alligator’s mouth. This approach not only helps students grasp the greater than (>) and less than (<) symbols, but it also makes learning more engaging by adding a playful element to math. By associating numbers with the visual of the alligator, kindergarteners can easily understand comparison, which reinforces their number sense in a fun and memorable way.

One activity that aligns with the unit that the students completed was an interactive activity where they used their bodies to create the comparison symbols. The students demonstrated great understanding and enthusiasm during the activity! To further develop this concept, the students were rolled two huge dice to pick two numbers to compare and demonstrate their understanding by drawing an alligator that “eats” the greater number. They were tasked with representing both numbers in a different way to showcase their comprehension. Their creations turned out so good that they are hung outside our classroom! Some station activities the students have completed include weighing manipulative bears to compare quantities, examining pictures of flowers with varying numbers of petals, building number representations, and using whiteboards to draw the amounts and symbols. As the week goes on, students will learn to compare more double digit numbers AND take a look at triple digit numbers!
