These crocodiles are hungry for the biggest numbers they can find! This is a fun way to illustrate number comparison; use crocodile mouths as the greater than and less than symbols. There are two examples (with teeth and eyes included) to show learners how the jaws always open towards the larger number, and learners compare 10 more sets. Consider displaying a number line as they complete this, asking them to locate numbers. How do they know which number is larger? The values here don't exceed 20.
