Understanding Word Problems: Roly Polies and Box Mass

The video tutorial covers two word problems. The first problem involves determining how many roly polies Dingan has if Leah has one more than him. The solution involves understanding the concept of 'one more' and 'one less' through subtraction. The second problem involves calculating the mass of a large box given that a small box is 7 grams less than the large box. This problem is solved by adding the difference to the small box's mass to find the large box's mass.

If Leah has 9 roly polies and she has one more than Dingan, how many does Dingan have?

• 9

• 8

• 10

• 7
