Ten Groups - Less Than, Greater Than

This math unit guides students through progressively complex skills in comparing numerical quantities using engaging visuals and practical symbols. Initially, children learn to compare quantities using a playful "alligator" metaphor to visually grasp "less than" and "greater than" concepts. They start with simple object comparisons and advance to using the alligator metaphor with numerical values, learning to associate the direction the alligator faces with the larger number. Next, the unit transitions from comparing individual numbers to using groups of tens and base ten blocks. This shift amplifies their understanding of number magnitude by embedding place value concepts in the comparison activities. The progression includes interpreting singular and compound numbers within ten and tens groups, using blocks to visually support their learning. Ending the unit, students are proficient in visually analyzing quantities using base ten blocks, discerning greater, lesser, or equal values using both the alligator metaphor and symbolic representations (<, >, =), crucial for foundational mathematics education.
