Understanding Base Ten and Number Order

This first-grade math lesson focuses on ordering whole numbers up to 120 using place value and open number lines. The lesson introduces key vocabulary such as 'order', 'open number line', 'least', and 'greatest'. Students learn to represent numbers using base ten blocks and a place value chart. The lesson demonstrates how to compare numbers by examining the largest place value first and then using a 120 chart to verify the order. The lesson concludes with an exit ticket activity involving plotting numbers on an open number line.
