Exploring Division

Mr. Added introduces backward skip counting as a method to understand division as repeated subtraction. The lesson begins with practicing backward skip counting by 10 and 5, then transitions to solving division problems using this method. Examples include dividing bricks and seashells into equal groups, demonstrating how backward skip counting helps solve division problems. The video concludes with a final example and encourages students to continue exploring division in future lessons.
