Long Division (Two-Digit Dividend) (Part 1)

This lesson teaches how to divide a two-digit number by a one-digit number using long division. The method is demonstrated by modeling the division of 84 by 3 with base 10 blocks. The process involves dividing the tens and units into groups and calculating the total units in each group to find the result. The lesson emphasizes understanding the division process through visual representation and step-by-step calculation.
