This math unit begins by teaching students the basics of numerical comparison using fun alligator visuals to explain less than and greater than concepts. Initially, students learn to associate the alligator mouth direction with comparing single-digit numbers. Progressively, they apply this understanding to the base 10 blocks system, starting with simple ones and advancing to comparing tens and ones. The unit continues to build complexity by introducing comparisons using hundreds and tens, and eventually thousands and hundreds. Through these steps, the unit develops foundational skills in understanding and visualizing numerical magnitudes using visual aids such as alligator symbols and base 10 blocks. This method enhances their capacity to understand the base ten numeration system, preparing them for more complex mathematical concepts related to counting, grouping, and place value understanding in comparative scenarios.
